How to Water Sweet wormwood?

Seedlings and young plants of sweet wormwood need regular watering. But once it matures, the plant becomes drought-tolerant, and no additional watering is required then. However, if the plant is cultivated in areas that are rainy or humid, you should pay attention to the drainage of the soil, as it may die back when the soil is soggy.

What is the best way to water my Sweet wormwood?
To water Sweet wormwood, you can use a garden hose with a spray nozzle, a watering can, or just about any other common watering tool. Generally, Sweet wormwood is not too picky about how they receive their water, as they can live off of rainwater, tap water, or filtered water. Often, you should try not to water this plant from overhead, as doing so can damage the leaves and flowers and may lead to disease as well. At times, the best method for watering this plant is to set up a drip irrigation system. These systems work well for Sweet wormwood as they apply water evenly and directly to the soil. For one Sweet wormwood that grows in a container, you can use a similar watering approach while changing the tools you use. To water a container-grown Sweet wormwood, use a cup, watering can, or your tap to apply water directly to the soil.

What should I do if I water my Sweet wormwood too much or too little?
The remedy for underwatering Sweet wormwood is somewhat obvious. When you notice that your plant lacks moisture, simply begin watering it on a more regular basis. The issue of overwatering can be a much more dire situation, especially if you fail to notice it early. When your Sweet wormwood is overwatered, it may contract diseases that lead to its decline and death. The best way to prevent this outcome is to choose a proper growing location, one that receives plenty of sunlight to help dry the soil and has good enough drainage to allow excess water to drain rather than pooling and causing waterlogged soils. If you overwater your Sweet wormwood that lives in a pot, you may need to consider changing it to a new pot. Your previous container may not have contained soil with good drainage or may not have had sufficient drainage holes. As you repot your overwatered Sweet wormwood, make sure to add loose soils and to use a pot that drains efficiently.

How often should I water my Sweet wormwood?
Sweet wormwood needs water regularly throughout the growing season. Beginning in spring, you should plan to water this plant about once per week. As the season presses on and grows warmer, you may need to increase your watering rate to about two to three times per week. Exceeding at this rate can be detrimental to your Sweet wormwood. With that said, you should also ensure that the soil in which your Sweet wormwood grows remains relatively moist but not wet, regardless of how often you must water to make that the case. Watering Sweet wormwood that lives in a pot is a bit different. Generally, you'll need to increase your watering frequency, as the soil in a pot can heat up and dry out a bit faster than ground soil. As such, you should plan to water a container-grown Sweet wormwood a few times per week in most cases, versus just once per week for an in-ground plant.

How much water does my Sweet wormwood need?
There are a few different ways you can go about determining how much water to give to your Sweet wormwood. Some gardeners choose to pick their water volume based on feeling the soil for moisture. That method suggests that you should water until you feel that the first six inches of soil have become moist. Alternatively, you can use a set measurement to determine how much to water your Sweet wormwood. Typically, you should give your Sweet wormwood about two gallons of water per week, depending on how hot it is and how quickly the soil becomes dry. However, following strict guidelines like that can lead to overwatering if your plant requires less than two gallons per week for whatever reason. When growing Sweet wormwood in a container, you will need to use a different method to determine how much water to supply. Typically, you should give enough water to moisten all of the layers of soil that have become dry. To test if that is the case, you can simply stick your finger in the soil to feel for moisture. You can also water the soil until you notice a slight trickle of excess water exiting the drainage holes of your pot.

How can I tell if i'm watering my Sweet wormwood enough?
It can be somewhat difficult to avoid overwatering your Sweet wormwood. On the one hand, these plants have relatively deep roots that require you to moisten the soil weekly. On the other hand, Sweet wormwood are plants that are incredibly susceptible to root rot. Along with root rot, your Sweet wormwood may also experience browning as a result of overwatering. Underwatering is far less likely for your Sweet wormwood as these plants can survive for a while in the absence of supplemental watering. However, if you go too long without giving this plant water, it will likely begin to wilt. You may also notice dry leaves.

How should I water my Sweet wormwood through the seasons?
You can expect your Sweet wormwood’s water needs to increase as the season moves on. During spring, you should water about once per week. Then, as the summer heat arrives, you will likely need to give a bit more water to your Sweet wormwood, at times increasing to about three times per week. This is especially true of Sweet wormwood that grow in containers, as the soil in a container is far more likely to dry out faster than ground soil when the weather is warm. In autumn, while your Sweet wormwood is still in bloom, it may need a bit less water as the temperature has likely declined, and the sun is no longer as strong as it was in summer.
Read More more
How should I water my Sweet wormwood at different growth stages?
Sweet wormwood will move through several different growth stages throughout the year, some of which may require more water than others. For example, you will probably start your Sweet wormwood as a seed. While the seed germinates, you should plant to give more water than your Sweet wormwood will need later in life, watering often enough to maintain consistent soil moisture. After a few weeks, your Sweet wormwood will grow above the soil and may need slightly less water than at the seedling phase. Then, once this plant is mature, you can begin to use the regular watering frequency of about once per week. As flower development takes place, you may need to give slightly more water to aid the process.

What's the difference between watering Sweet wormwood indoors and outdoors?
There are several reasons why most Sweet wormwood grow outdoors rather than indoors. The first is that these plants typically grow to tall. The second reason is that Sweet wormwood needs more daily sunlight than most indoor growing locations can provide. If you are able to provide a suitable indoor growing location, you may find that you need to give your Sweet wormwood water a bit more often than you would in an outdoor growing location. Part of the reason for this is that indoor growing locations tend to be a lot drier than outdoor ones due to HVAC units. The other reason for this is that soil in containers can dry out relatively quickly as well compared to soil in the ground.

How to Fertilize Sweet wormwood?

Sweet wormwood does not like rich soils, so it does not require any additional fertilizers. Over-fertilization may lead to leggy growth and look badly. Just use a little compost, manure or other organic fertilizers in spring or fall, then it will provide all the necessary nutrients for the plant.

Fertilizer

Sweet wormwood is grown for its attractive foliage. It does best when it is grown in a rich potting mix with a neutral pH level. If the soil is rich enough, it may not be necessary to provide any extra nutrients in the form of fertilizer. However, this plant can benefit from frequent, weak doses of fertilizer to keep leaves growing well. And, if you want your Sweet wormwood to produce move leaves, you will need to provide both sufficient fertilizer and a lot of moisture.
All plants need nutrients to grow, but some types are able to take what they need and don’t need any supplementation with fertilizers. Sweet wormwood, like other plants, use nutrients to support growth and all internal processes. Each of the main nutrients that plants use (nitrogen, phosphorus, and potassium) contribute to one or more of a plant’s essential functions, and in the case of foliage it is nitrogen that provides the most support. It can be difficult for a Sweet wormwood to get enough nitrogen from the soil , which is why many gardeners prefer to supplement by feeding Sweet wormwood with a source of nitrogen.
Sweet wormwood generally grows well, but a fertilizer can be applied about once a month to give the plant a boost when it is actively growing. You should fertilize Sweet wormwood about once a month only during the spring and summer months, but not during fall and winter when it becomes less active and does not use as many nutrients.You’ll know when to start fertilizing Sweet wormwood if you see signs of new growth. The fertilization schedule remains the same whether the plant is grown outside or indoors in a container. However, if your Sweet wormwood is in a container, you probably will not need to fertilize for the first one to two months. Potting soil made for container plants already contains plenty of nutrients, so you should only start to fertilize after your plant has been in the same soil for a while.
A balanced fertilizer works well for Sweet wormwood, for example an all-purpose fertilizer with a 10-10-10 NPK number. For natural fertilizers, blood meal or worm castings work well. You may also choose a fertilizer that is higher in nitrogen than other nutrients, such as fish fertilizer. Nitrogen provides support to leaves, which are the main feature that people want from Sweet wormwood. There is no point in providing a lot of supplements for flowers or seeds if that is not your purpose in growing the plant. Apply fertilizer based on the instructions on the particular type you have purchased. It is generally a good idea to start with half-strength fertilizer to avoid accidentally over-fertilizing your Sweet wormwood. Since this plant requires frequent fertilization, it is common to accidentally fertilize too much. Remember that it’s always easier to add more fertilizer than it is to try to save an over-fertilized plant. Don’t apply fertilizer to dry soil - it should already be at least somewhat moist before fertilizing. This helps the fertilizer absorb more easily and helps avoid fertilizer burn. You should also water after applying dry fertilizers to your soil.
Some fertilizers are meant to be mixed into the soil when planting, while others are applied on top of the soil and then watered in. For most types of Sweet wormwood, a water soluble fertilizer is an easy choice. Simply mix the fertilizer solution into your watering can at the recommended dosage for Sweet wormwood and then water the plant as usual. Slow-release granules or fertilizer spikes can also work well if you prefer not to remember to fertilize monthly.
Over-fertilization leads to a build-up of salts in the soil which leads to a lack of vitality overall and pale coloration in the leaves. Leaves may also wilt or develop brown tips as the excess salt from the fertilizer tries to make its way out of the leaves. Too much fertilizer makes it impossible for the plant to take up water and nutrients, which will eventually kill it if you don’t take steps to save your Sweet wormwood. If the Sweet wormwood is in a container, you could either remove it from the pot and repot it in fresh potting mix, or flush out the soil by running a lot of water through and letting it drain out thoroughly. If your Sweet wormwood is outdoors, the same theory applies, although it can be more difficult to flush outdoor soil. Water thoroughly and hold off on fertilizing again for a while. You may want to perform a soil test before you add any more fertilizer to make sure you don’t provide too much of any one nutrient.
Never fertilize your Sweet wormwood if it is not healthy, for example if it has developed a disease or has insect pests on it. Also do not fertilize a dehydrated plant, since the fertilizer will make this problem even worse. Only fertilize healthy plants. Do not splash fertilizer onto the leaves or stem of this plant when watering, since it can cause burned spots. Be careful not to allow the fertilizer to make direct contact with the plant, unless you are usually a special fertilizer designed to be applied to the foliage.

How much sunlight should Sweet wormwood get per day to grow healthily?
You must expose the plants to at least 6 to 8 hours of sunlight daily. They prefer more exposure to the morning light, especially in the summer. The Sweet wormwood needs full sun and more sunlight that it can get. The more light these species get, the more they can manufacture food, produce beautiful blooms, and survive.
Read More more
What type of sunlight does Sweet wormwood need?
The Sweet wormwood grows best under full sunlight. It's best not to crowd them together so they can get exposure to the sun evenly. The leaves shouldn't be starved with sunlight. If planted in pots, try to expose the herbaceous flowers in windows with direct sun and ensure they receive full sunlight regardless of the months.
They don't tend to do well in partial or filtered light as this will not produce strong stems and healthy flowers. It's best if the Sweet wormwood is always exposed to the sun.
Read More more
Can sunlight hurt plants? How to protect Sweet wormwood from sun and heat damage?
When the temperature rises above 90℉(32℃), the Sweet wormwood can get damaged by extreme temperatures, especially if they are exposed to many hours of sun. It's always ideal for providing some shade from the light in the afternoon in the summer. It's always important to keep in mind that the sunlight in the summer is stronger than the one in the winter. Sunlight exposure is also 50% longer in the summer than in the winter.
If the Sweet wormwood is too stressed with sunlight, you might want to keep them fully hydrated. Water them when the top of the soil is about 2 inches dry, and move the plants indoors if it's too hot outside. This is the case if they are planted in containers.
It can be normal for the plant leaves to wilt during the day. Generally, they can recover at night. However, when you notice that the Sweet wormwood is still drooping, this means that the plant is losing water fast, and you need to water them.
Read More more
Should I protect Sweet wormwood from sun exposure?
The Sweet wormwood does not need any protection from the sun. In fact, they love the sun, and some species are heliotropic. Plant them in south-facing gardens whenever possible so they can be exposed from morning to afternoon. While the sun can benefit them, some may experience a sunburn. You might offer protection from the afternoon and midday sun through a shade of a tree or a wall.
Growing the Sweet wormwood in shady areas is impossible because the larger flowers would require a lot of energy to grow and produce. Always provide the lighting conditions and set them in an area with full sun for best results.
Read More more
What will happen if Sweet wormwood gets inadequate sunlight?
When the Sweet wormwood does not get adequate sunlight, or they are not placed in full sun locations, it's worth noting that the photosynthetic process will slow down. A lack of sunlight will cause the stems to become more leggy since they become thin and long since they tend to seek too much sunlight. They will not bloom and produce seeds in the shade.
Inadequate sunlight will also mean that the older leaves can die, the color of the new ones is lighter than the old foliage, and the new growth is smaller than the last ones.
The Sweet wormwood indeed loves the sun so much. However, they can wilt when exposed to excessive heat and ultraviolet light during the extreme summer months, so be careful. You might want to cover them with a net that has a green shade, especially in the summer, to prevent the leaves and the flowers from scorching. When they are indoors, reduce the heat with the help of a fan.
Read More more
Does Sweet wormwood need special care about sunlight during its different growth stages?
When the Sweet wormwood is growing, they need more light than their mature counterparts. The younger ones should receive adequate light, but they might not be prepared for sudden full sunlight, especially if they are grown in a nursery. They can be more sensitive to the summer sun, so the lighting should be gradual and slow.
Read More more
How much light does Sweet wormwood need for photosynthesis?
During summer or late spring, the Sweet wormwood needs 6 to 8 hours of direct light every single day. This is whether they are planted outdoors. If the Sweet wormwood is planted in pots or you're growing them in the winter, they need direct fluorescent lights that help them grow better. Make sure to place them in an indoor area where they are facing south or east so they can have enough sunlight for photosynthesis.
Read More more
Are there any cautions or tips for sunlight and Sweet wormwood?
When transplanting the plants, they should not be exposed to sudden sunlight. Give the Sweet wormwood to grow and mature before transplanting outside. Some species of herbaceous plants can grow taller and might cast a shade on other young plants. Allow between 80 to 100 days of growing season before planting another batch to ensure that every plant receives more than enough sunlight for at least 6 hours a day.
Make sure that the Sweet wormwood receives the best light possible, especially if it's planted in a nursery. These are sun-loving plants, but too much sunlight with a very hot temperature is also detrimental to their growth. Indoor lights should be replaced with natural sunlight as much as possible since these species crave this every day.

Cultivation:PruningDetail

How to Prune Sweet wormwood?

Pruning method is quite different for different species and cultivars. Generally, you can cut your Artemisia plants back to the base in fall or spring to encourage growth in the following year. While with evergreen or late-flowering species such as tree wormwood (Artemisia arborescens) and sweet wormwood (A. vallesiaca), pruning should be performed in early spring, when there is no danger of frost, but before the new growth starts. Remove wilt flowers as well as dead branches, and leave only new shoots.
If the plant is not pruned, it can get really tall (1.5 to 1.8 m). Trimming some terminal leaves and branches in summer, can return the plants that grow wild into a more favorable shape. If the plants get very bushy and thick, the air between the leaves will become more humid – favorable for powdery and downy mildew to develop. Thinning out the plants a little bit to improve the airflow and prevent these diseases. More intensive thinning is necessary if the plants are grown in very humid climates.
Besides, it is very important to wear gloves while pruning sweet wormwood because its repelling chemicals can also irritate the skin.

Is pruning necessary for my Sweet wormwood?
Sweet wormwood is a kind of annual plant so it doesn't need much pruning. You only need to cut off and clean the diseased, yellow or dropped leaves and stems during its growing period. This will help your Sweet wormwood to stay away from pathogens infection.
Read More more
How do I prune my Sweet wormwood?
During the growth of the plant, yellowing, drying and spotted leaves are produced, and these spotted and discolored leaves need to be trimmed off. If the whole piece of leave is discolored or infected, you will need to cut it off completely. In other situations, you will only need to cut off the discolored or infected part on certain leaves. Sweet wormwood above the ground will die and dry up in the winter, and the dead plants need to be cleaned up.
Read More more
Are there any cautions I should be careful with when pruning my Sweet wormwood?
Sweet wormwood leaves are delicate, so take care not to score or bruise them. Unless the leaves are withered or heavily discolored, do not prune the leaves from the lowermost branches unless they’re damaged. They typically grow the largest, so they supply the plant with critical energy to keep it growing right. Please prevent the wounds from water after pruning until they are fully recovered. Remember always sterilize the tools before pruning. When the pruning is finished, please throw all the waste leaves and stems into the trashbins to avoid diseases and bugs.

Are there any tips for pruning my Sweet wormwood?
  1. Sterilize all the tools before pruning; unclean tools will pass pathogens to the plant through wounds;
  2. Prune on sunny days because the new cuts will be infected by pathogens if they're distained by rain or water.
  3. Throw all the waste leaves and stems into trashbins, they will easily rot and attract diseases and bugs

When should/shouldn't I prune my Sweet wormwood?
Expect to prune your Sweet wormwood every week if it’s growing well or every two weeks if it grows slowly. It is always good to prune it on sunny days because if you prune it on rainy days, the rainwater will distain the cuts and cause the whole plant to be infected.
Read More more
What should I look for when pruning my Sweet wormwood in different seasons?
Because Sweet wormwood is an annual plant, the pruning should take place basically during the seasons that the plant grows rapidly. During the growth of the plant, yellowing, drying and spotted leaves are produced, and these spotted and discolored leaves need to be trimmed off.

What is the Ideal Temperature Range for Sweet wormwood?

As part of Artemisia genus, sweet wormwood is hardy due to the wide distribution of this genus – they can be found from temperate to tropical climate zones on both hemispheres, most commonly in semiarid and arid habitats.
Sweet wormwood is drought-tolerant, just like most perennials with silver-gray leaves (i.e. foliage is covered by silver hairs that can suppress evaporation), and do not have any specific water requirements.
Cultivation:WaterAndHardinessDetail
What is the optimal temperature for Sweet wormwood?
The best temperature for Sweet wormwood depends on the time of year. There are two primary seasons to discuss for temperature: the growing season, and the dormancy season. During the growing season, once Sweet wormwood has begun to sprout, the ideal temperature range should be anywhere from 65~80℉(18~27℃). Any colder than 15℉(-10℃), and the plant will suffer; its leaves may brown and wilt, but if this is a short cold snap, then Sweet wormwood may be able to survive with some help.
During the warmer parts of the year, Sweet wormwood will need to be similarly protected from temperatures that are too high. 95-105℉ (35-40℃) is the top of this plant’s temperature range, and anything above that will compromise the integrity of the foliage and blooms of Sweet wormwood. Hotter temperatures can cause wilting, drooping, and even sunburn on the leaves, which can be difficult for Sweet wormwood to recover from. There are quite a few ways to combat this issue that are quick and easy!

Temperature requirements for first year or seedling Sweet wormwood
If this is the first year of your Sweet wormwood outside as a new plant, then it may need a little extra tending during the coldest months of the year. Not only can frost more severely damage a first-year Sweet wormwood, but it can also prevent it from growing back as a healthy plant come spring. This plant needs to be kept at 40℉(5℃) or above when they’re not yet established, which can be done either by bringing your Sweet wormwood inside for a month or two, or putting up mulch or fabric barriers that protect from frost damage.
It’s also a good idea to plant Sweet wormwood in a shadier spot during the first year or two, as smaller and weaker plants have a more difficult time maintaining their own temperatures in the heat. First-year Sweet wormwood should receive no more than five hours of direct sunlight per day, particularly if the ambient daytime temperature gets above 80℉(27℃). Shadecloth and frequent watering or misting are the keys to summer heat control.

How can I protect Sweet wormwood from extreme temperatures?
If cold temperatures (below 15℉(-10℃)) do occur during the growing season, there are a few measures you can take to help protect Sweet wormwood from frost or cold damage. If you’re growing Sweet wormwood in a container, then the container can simply be brought inside in bright, indirect light until the temperatures rise up over the lower threshold again. Another option that’s better suited for ground-planted Sweet wormwood is to use mulch or horticultural fabric to create an insulated barrier around the plant, which will protect the plant from frost and cold wind.
For temperatures that are hotter than 80℉(27℃) in the shade during the day, be careful to only expose Sweet wormwood to six hours or less of sunlight per day, preferably in the morning hours. Putting up shade cloth, or a fine plastic mesh, can help reduce the amount of direct sunlight that hits the plant during the hottest parts of the day. You can also install a misting system that allows for a slow release of cooling mist around the base of the plant during the day to lower ground temperatures.

Dormant season temperature recommendations for Sweet wormwood
During the cold winter months, Sweet wormwood needs a certain measure of cold in order to stay in dormancy until it’s time to sprout. Sprouting too early, that is before the danger of the last frost has passed, can be fatal to Sweet wormwood, especially if it’s already had a head start when the frost hits. Winter temperatures should ideally stay below 32℉(0℃), but if they get up to 40℉(5℃), everything will be just fine.
An unexpected warm spell during the cold months, which can happen in more temperate climates like woodland rainforests, can trigger a premature sprout from Sweet wormwood. In this case, if there’s still imminent danger of frost, you may want to try covering it with clear plastic on stakes so that the cold has less of a chance of damaging the new sprout. This setup can be removed when the danger of frost has passed. Occasionally, Sweet wormwood will be able to resprout at the correct time without any help, but this method increases the chances of a successful second sprouting.

What Soil is Best for Sweet wormwood?

Sweet wormwood does not have any specific requirements when it comes to soil structure and pH, but they will not develop well in very rich and heavy soils. It is best if the soil is poor to moderately fertile and well-drained with a small to moderate amount of moisture.
Cultivation:SoilDetail
Cultivation:PropagationDetail

How to Propagate Sweet wormwood?

Sweet wormwood can be propagated by seeds (some annual Artemisia species are self-sown) or cuttings. Propagation by cuttings includes taking 8 to 10 cm cuttings in late summer and rooting them in a loose, sandy compost or perlite. It is best if the rooting powder is applied before putting the cutting into the medium. Spray water every couple of days to keep it moist.
After a week or two, the cuttings will root. When the roots start protruding from the medium, it is time for a transplant. Rooted cuttings can be put into a separate container or planted directly into the soil in the garden. The distance between the cuttings should be at least 38 cm.

Propagation

Only sow Sweet wormwood seeds in warm weather, preferably during the later weeks of spring after any danger of frost or dropping temperatures has passed. Even in warm climates, ensure the soil is sufficiently warm, as cooler soil can hinder germination and growth. If you want to sow the seeds earlier, you need to do it indoors for successful germination.
To sow Sweet wormwood in your growing medium, you don't need many extra tools. Simply put on your gardening gloves and get started!
What you will need:
  • Healthy and full seeds, as the germination rate of such seeds will be higher.
  • Growing medium with potting mix soil, divided into rows.
  • Fertilizer or compost.
  • (Optional) A dibbler or stake.
  • A spray bottle to hydrate the soil.
  • (Optional) A piece of plastic film.
Steps:
  1. Prepare the soil: Mix the soil with organic fertilizer. Fully rotted fertilizer is recommended, and its volume should not exceed one quarter of the soil volume when mixing.
  2. Sow the seeds: Sprinkle the seeds onto the soil and cover them afterwards. Alternatively, use a dibbler or stake to pre-dig holes for the seeds, placing about 3 seeds in each mound. The depth of the soil covering the seeds should be about five times the thickness of the seed.
  3. Space the seeds: Leave a 4-6-inch gap between each seed mound.
  4. Water the soil: After planting, water the soil in the container well to provide enough moisture for the seeds to germinate.
  5. Mulch and maintain: Mulch the surface of the container soil to retain moisture and promote seed germination. Use a spray bottle to moisten the soil when it becomes relatively dry. Continue this until the seeds germinate.
Note: Before seeds germinate, they can be kept in a low-light location. However, after germination, it's important to provide adequate light to the plant to prevent excessive growth.

How to Plant Sweet wormwood?

You can easily purchase the seeds or seedlings of sweet wormwood from a nearby gardening store. Choose a sunny location with soil that is poor to moderately fertile and well-drained. Simply sow the seeds or plant the seedlings where optimum for them in spring or fall. If you grow sweet wormwood in containers, place the pot onto a sunny windowsill.
As contains compounds that provide a good defense against insects and herbivores, sweet wormwood can inhibit the growth of edible plants nearby when these chemicals leach into the soil. It is advised to plant sweet wormwood amongst other species in your garden to protect them. If sweet wormwood is used as a natural pest repellent, it is necessary to properly isolate it from other plants by planting it into a separate container or at a safe distance (the stem should be at least 1.2 to 1.5 m away from the nearest plants).

Seasonal Precautions

Covering the soil beneath sweet wormwood with mulch can protect it from soil frost. If the winter is dry, the plant may need some additional water, especially the evergreen species. If the plant is grown in colder climates, it is advised to grow it in containers and put it inside during the winter.
During the blooming season, sweet wormwood produces a lot of pollen, which can cause very negative effects on people with allergies. So cutting the flower buds before blooming can save you from sneezing and running nose. However, you then will miss the enjoyment of the blooms of sweet wormwood.

Common Pests & Diseases

Common issues for Sweet wormwood based on 10 million real cases
Leaf rot
Leaf rot Leaf rot
Leaf rot
This pathogen can cause the leaves to rot.
Solutions: Bacterial infections need to be treated quickly to prevent the spread to neighboring, healthy plants, potentially wiping out large sections of your indoor or outdoor garden. In mild cases: Use sterilized (10% bleach solution) pruning shears or scissors to remove any infected plant parts, making sure to dispose of them off site. Use a copper-based bactericide to treat the unaffected foliage, as well as the soil, and neighboring plants. Follow the manufacturer’s rate and timing directions found on the product label. In severe cases, where more than half the leaves are affected: Remove all of the infected plants from the garden, disposing of them off site. Treat the soil and neighboring plants using a copper-based bactericide. Follow the manufacturer’s rate and timing directions found on the product label.
Thrips
Thrips Thrips
Thrips
Thrips are 1 to 2 mm bugs with slender black or translucent-yellow bodies. They move quickly and feed on the plant's sap.
Solutions: Thrips can be controlled in several ways. Spray plants with Pyrethrin, which is an organic pesticide derived from marigolds (follow label instructions) or Permethrin, the synthetic version of Pyrethrin. Introduce beneficial insects to the garden that eat thrips, such as minute pirate bugs and green lacewings. Remove heavily infested plants from the area and discard. Address viral diseases that may have been transmitted by the pests. For less serious cases -use a hose to spray the thrips off of the plants.
Nutrient deficiencies
Nutrient deficiencies Nutrient deficiencies
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Solutions: There are several easy ways to remedy the nutrient deficiencies in soils. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.
Leaf beetles
Leaf beetles Leaf beetles
Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.

Leaf rot
plant poor
Leaf rot
This pathogen can cause the leaves to rot.
Overview
Overview
Leaf rot is very common among both house plants and garden plants. It affects foliage and occurs mainly when the leaves become wet due to rain or misting by the gardener. The cause is fungal disease and this is facilitated by the fungal spores adhering to wet leaves then penetrating the leaf and expanding rapidly. Damp conditions and poor air circulation will increase chances of infection taking place. Another factor are leaves that are damaged or have been penetrated by sap sucking insects that facilitate plant penetration.
Symptom Analysis
Symptom Analysis
  1. Spores are able to cling to a damp leaf and penetrate, often through an existing wound.
  2. A small dark brown mark appears which expands rapidly as sporulation starts to take place.
  3. Quite quickly these bull's eye like circles can link together and the whole leaf turns dark and loses texture.
  4. Leaf drop occurs.
Disease Cause
Disease Cause
These symptoms are caused by a bacterial infection invading the plant. Bacteria from many sources in the environment (air, water, soil, diseased plants) enter a plant through wounds, or in some cases the stomata when they are open. Once inside the leaf tissue, the bacteria feed and reproduce quickly, breaking down healthy leaves.
Bacterial infections threaten most plant species, and are more prominent in wet weather that more easily transfers the bacteria from plant to plant, or from soil to plant.

Thrips
plant poor
Thrips
Thrips are 1 to 2 mm bugs with slender black or translucent-yellow bodies. They move quickly and feed on the plant's sap.
Overview
Overview
Thrips are tiny, flying, sap-sucking insects that attack the tender parts of plants, causing scarring and weakening of the plant and sometimes, if the infestation is severe enough, plant death. They have undersized double wings with a fringe on them, resembling tiny, misshapen damselflies. Thrips have a taste for many houseplants and crops, making them a serious nuisance.
They appear in early spring after the last frost has occurred. If not controlled in early spring, they will persist for most of the season. They are often attracted to weakened plants, such as those struck by drought/underwatering or malnutrition. Excessive use of nitrogen fertilizer also seems to attract them to a plant. Thrips can spread various viruses between plants, leading to more serious damage.
Symptom Analysis
Symptom Analysis
Thrips are so small that they may not be noticed (1 to 2 mm long), but infested plants present several key signs. Tiny pale spots appear on leaves, which may start to deform, show white or silver discoloration, or become papery in texture.
Flower petals may be damaged as well, and might display color break, which is dark or pale discoloring of petal tissue damaged before the buds had a chance to open. Fruits may show scabby or silvery scarring. Tiny black spots of the insects' excrement may be visible.
As the infestation progresses, infested terminals roll and become discolored, and leaves may drop prematurely. The plant's growth may be stunted. Secondary viral and bacterial infections, which thrips can transmit, may become evident.
The good news? Thrips rarely kill or seriously weaken shrubs and trees. Smaller plants, such as vegetable crops and herbaceous ornamentals, tend to be more severely affected.
Solutions
Solutions
Thrips can be controlled in several ways.
  • Spray plants with Pyrethrin, which is an organic pesticide derived from marigolds (follow label instructions) or Permethrin, the synthetic version of Pyrethrin.
  • Introduce beneficial insects to the garden that eat thrips, such as minute pirate bugs and green lacewings.
  • Remove heavily infested plants from the area and discard.
  • Address viral diseases that may have been transmitted by the pests.
  • For less serious cases -use a hose to spray the thrips off of the plants.

Nutrient deficiencies
plant poor
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Overview
Overview
Nutrient deficiencies can be seen in many different ways on plants. Basically, the lack of nutrients will inhibit plant growth, produce weak stems and leaves, and leave plants open to infection from pests and diseases. Plants use the nutrients from the soil to help them with photosynthesis. This, in turn, produces healthy plant growth. Plants that lack adequate amounts of nutrients will look lackluster and unhealthy. Eventually, if this is not addressed, it will cause the plants to die. The most important nutrients that plants need are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Additionally, plants require small amounts of micronutrients such as iron, boron, manganese, zinc, copper, and molybdenum.
Symptom Analysis
Symptom Analysis
A common sign that plants are experiencing nutrient deficiencies is the yellowing of leaves. This may be an overall yellowing or leaves that are yellow but still have green veins. These leaves will eventually brown off and die.
Another sign is the loss of plant vigor. The plants may not be growing as well as they should or their growth may be stunted.
Below are some common symptoms that appear when plants are lacking in nutrients.
Nitrogen (N): Inner, older leaves yellow first. If the deficiency is severe, yellowing progresses outward to newer growth.
Potassium (K): Leaf edges may turn brown and crinkly, with a yellowing layer forming just inside of the edge. Older leaves tend to be impacted first.
Phosphorus (P): Lack of vigorous growth. Plants will appear stunted.
Zinc (Zn): Yellowing tends to occur first at the base of the leaf.
Copper (Cu): Newer leaves begin to yellow first, with older leaves yellowing only if the deficiency becomes severe.
Boron (B): Newer leaves are impacted first. Foliage may also become particularly brittle in cases of boron deficiency.
Disease Cause
Disease Cause
There are several factors that can lead to nutrient deficiencies, a situation where plants are not receiving the nutrients that they need. This could be because they are planted in nutrient-deficient soils, or that the soil's pH is too high or low. Incorrect soil pH can lock up certain nutrients, thus making them unavailable to plants. Lack of soil moisture can also be a problem, because plants need water to be able to absorb the nutrients from the soil.

Leaf beetles
plant poor
Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Overview
Overview
Leaf beetles range in size from 1.5 mm to 2 cm. Both adult beetles and their larvae eat the leaves of many different types of plants. There are over 35,000 different species of leaf beetles, in a variety of colors including gold, green, yellow-striped, and red striped. Some of these have been mistaken for ladybirds because of their shape and coloring. They can be oval, round, or elongated in shape. These insect pests are most active in spring and summer.
If not controlled, leaf beetles can do a lot of damage to vegetable crops and ornamental plants. They feed on the leaves, flowers, stems, roots, and fruits of different plants. They can fly, which means it's easy for them to move from one plant to another. Some species of leaf beetles only target one specific crop, while others will target many different types of plants. Although a lot of the damage that they cause is cosmetic, an infestation can weaken a plant and leave it prone to other more problematic diseases.
Symptom Analysis
Symptom Analysis
The first signs of a leaf beetles infestation are small visible holes in leaves. Leaves then become discolored and dark beetle droppings can be seen. As the leaves turn yellow and brown, they will drop off the plant onto the ground. Some leaves will appear skeletonized with only the veins still remaining.
Infestation begins in spring, when the adult beetles emerge from the soil and lay their eggs on the leaves of plants. When these eggs hatch, the young nymphs start munching on the leaves as they grow up. Once leaf beetles are large and mature, they'll fall to the ground and pupate in the soil over winter before starting the cycle all over again.
Leaf beetles also eat holes in fruits and vegetables. These can be seen as small round holes that sometimes have a larger brown area surrounding them.
Solutions
Solutions
For less serious cases:
  1. Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread.
To treat more serious infestations:
  1. Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions.
  2. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.

Common Toxic Houseplants
Common Toxic Houseplants
When it comes to decorating a house, there is nothing more refreshing than adding some beautiful houseplants. Some common house plants can also be toxic.

Aloe

aloe
Aloe is famous for its sunburn-soothing properties and its gorgeous desert design. However, many people do not realize that the latex the aloe vera plant produces can be mildly toxic to pets and children.

The latex contains a chemical compound known as saponin. Which when ingested, can cause vomiting, diarrhea, and low blood sugar. This, if left unchecked, can lead to dehydration and electrolyte imbalance. The proper response is to contact poison control or a veterinarian to know what to do in your particular circumstance if either your child or pet consumes aloe.

The latex of the plant is similar to the sap of the tree. It is inside the leaf, but sticks mainly toward the edges. If aloe gel is prepared properly it should be safe for use, but be sure to apply it only topically when treating burns.

Philodendron

Philodendron
Philodendron, also known as sweetheart vine, has become a resident at many houses and even businesses. They are glossy green and the leaves elegantly split, displaying interesting designs. Behind this beauty there is a needle-like toxin called calcium oxalate crystals.

These crystals are held within the plant and only affect you, your pets, or your loved ones if the plant tissue is broken. If ingested, the crystals can cause severe swelling, difficulty breathing, stomach pain, burning and pain. If they are accidentally caught on the skin, they can cause skin irritation.

If anyone accidentally ingests philodendron and they find it difficult to breathe or their tongue starts to swell up, it is important to seek medical attention immediately to avoid suffocation. If you have very young children or pets who have a tendency to tear at plants, keep them away from any philodendrons.

Peace Lily

Peace Lily
Peace lilies produce stunningly white flowers that bring to mind peace and serenity. This is one reason they are invited into our homes and given a place to stay. However, similar to philodendrons, the peace lily contains oxalate crystals known as raphides.

The raphides, once ingested, will cause swelling and burning sensations and can also cause skin irritation. Both pets and humans can get these symptoms so it is important to keep these plants from anyone who is likely to tear or chew it. Symptoms can become dire if the raphides cause the tongue and throat to swell to a point where the person or pet is having difficulty breathing. Seek proper medical attention if this is the case.

Snake Plant

Snake Plant
The snake plant is an interesting and popular house plant. Its stark architecture and wavy coloring has made it a fan favorite. This plant too, however, is toxic when ingested or if the sap touches your skin.

Snake plant sap will cause rashes if it comes into contact with your skin. In addition, it will cause diarrhea and vomiting when ingested. Again these symptoms are very serious and would be best avoided by keeping snake plants out of reach or by choosing a different houseplant.
Common Toxic Garden Plants
Common Toxic Garden Plants

Daffodil

Daffodil
Daffodils are a strikingly colorful flower. This can sometimes bring them much attention not from just onlooking adults but children as well. Since kids are more drawn to colorful objects, they may have a higher chance of just grabbing the flower and eating it. Adults have also been known to accidentally grab daffodil bulbs instead of onions.

Why are these mistakes so dangerous? Daffodils contain lycorine, which can induce nausea, vomiting, and diarrhea. It also contains oxalates which can cause swelling and pain. The symptoms can be worse in animals, because if your pets eat daffodils they may experience drowsiness, low blood pressure or even liver damage.

Make sure to call poison control when these symptoms set in. The vomiting and diarrhea have been known to go away after 3 hours, but it is better to be safe than sorry. Ingesting liquids to keep hydration up can be important. If the patient is having difficulty breathing, seek medical attention immediately.

Hydrangea

Hydrangea
Hydrangeas are unique, with their soft blue and pink flowers. They are a great addition to any garden, but should not be snacked on—not that you would want to. Hydrangeas can be especially nasty because they contain compounds known as glycosides. These will release hydrogen cyanide into the bloodstream when consumed. This will block your body’s ability to uptake oxygen to the cells in your body.

The way to combat this kind of poisoning is through getting IVs from the vet or doctor. It is important to contact your medical professional immediately since the symptoms can be fatal within minutes or hours.

Rhododendrons

Rhododendrons
Rhododendron, the state flower of Washington, is also toxic. The multitudinous, pink flowers can be quite dangerous. All parts of this plant are toxic, the leaves and seeds more so than the flowers. However, even the nectar of the flower is toxic and in the Mediterranean, where rhododendrons grow in more dense quantities, the honey from bees who gather rhododendron nectar can be poisonous.

Normally kids and pets do not eat enough to experience the full poisoning effect. However, just eating two leaves is enough to be considered dangerous. The grayanotoxin glycosides within the rhododendron can cause vomiting, diarrhea and irregular heartbeats. Things can get very serious when too much rhododendron is consumed and can lead to necessary medical intervention.

Start by calling poison control first if you suspect anyone has been munching on rhododendrons. The experts there will be able to help guide you through the necessary processes to cure your loved one.

Rhubarb

Rhubarb
Yummy rhubarb has a nasty side to it. While the stems are used in many recipes, including for rhubarb strawberry pie, the leaves are toxic. They contain oxalic acid which is known to blister the mouth, cause nausea, vomiting, diarrhea and kidney stones. The leaves are known to be more toxic to pets than humans, but in either case, it is important to contact poison control immediately to figure out necessary steps to cure the patient.
Common Toxic Weeds in the Yard
Common Toxic Weeds in the Yard

Bittersweet Nightshade

Bittersweet Nightshade
Nightshade is an invasive, noxious weed that is extremely poisonous. It has been found along the East and West Coast of the U.S. It makes its home in areas with disturbed soil. This could be near your garden or areas that have recently had bushes/trees put in.

These plants are dark green with purple flowers that develop into bright red berries. The whole plant is toxic and should be avoided by pets and children alike. If ingested it can cause nausea, vomiting, and diarrhea. The colorful berries are especially enticing to young children. If you see any plants that look similar to tomato or pepper plants that you did not plant in your yard, it is best to just pull them immediately.

Call poison control immediately if you think someone has fallen victim to nightshade.

Buttercups

Buttercups
Buttercups are found throughout the United States, especially in wet areas. The shiny, yellow flowers will pop up in the springtime, accompanying their dandelion friends. However, unlike dandelions, buttercups are not edible.

Buttercups will release a compound called protoanemonin. This toxin is known to cause vomiting, diarrhea, bloody stool, hypersalivation, depression, blisters, and more. These symptoms will affect both humans and animals. The sap may also cause irritation when it comes into contact with skin. These yellow flowers are dangerous and children should be observed cautiously when around them.

Foxgloves

Foxgloves
Foxgloves are beautiful plants that build towers out of vivid purple bell-shaped blossoms. They are very pretty to look at, but they contain a compound known as digoxin. This chemical is used in certain medicines to help people with certain heart conditions. However, the medicine is made by specialists, whereas someone eating foxgloves will receive unregulated amounts of the chemical.

This toxin can make you vomit and lower your heartbeat. This often causes dizziness and faintness. It is extremely important to call poison control immediately to know what to do in the case of foxglove poisoning. Some people have confused the young leaves of foxglove with borage, making adult foragers at risk as well as kids and pets.
How to Tend to or Get Rid of Toxic Plants
How to Tend to or Get Rid of Toxic Plants
Now that you know where to start with toxic plant identification, let us discuss how to either tend to the poisonous plants you decide to keep or get rid of them that plague your yard.

How to Tend to Poisonous Plants

Many plants that are toxic when ingested are also skin irritants. The philodendron is a good example of this. When the sap comes into contact with skin, it can cause a rash to form. To help protect yourself when tending to toxic plants, it is important to wear some sort of gloves.
Tend
Latex gloves may be the best solution due to their disposability. Regular gloves could potentially keep the poisonous sap on their surface. If the gloves aren’t cleaned then you could accidentally touch the irritant or pass it to someone else.

In addition you will want to plan where to keep your deadly beauties. If you have a toxic indoor plant try to keep it up high or out of reach of children and pets. This will keep accidents few and far between. Another idea is keeping your plants in areas that are usually inaccessible to children or pets. Areas such as an office, study room, or guest bedroom could be good locations. If applicable, you could also set up a terrarium for your little plant baby, making it more difficult for curious hands or paws to access.
tend2
If you plan to have outdoor plants, location will be key. You will want to put plants in an area that will be inaccessible to children, pets and even wild animals. You will probably want to avoid planting the plants in the front of your house if kids walk by on a regular basis, just to be cautious. Having the plants behind a fence will be best, but use your discretion when choosing a spot.

How to Get Rid of Poisonous Plants

plants
The easiest but possibly most controversial way to get rid of poisonous plants is by using herbicides. This can be especially easy if you own a grass lawn and use an herbicide that targets broadleaf (non-grass) species. You can find many herbicides meant for yard use by simply searching the term online. Once you have purchased the herbicide you will want to make sure to follow the label posted on the container. If you follow the instructions precisely, then everything should run smoothly for you.

If you don’t plan on using herbicides, there are a few organic methods you can use to try to get rid of toxic plants. You can manually pull the plants out of the ground. This is probably one of the most difficult methods because there is no assurance that you will get the whole plant out this way.

You can also try pouring boiling hot water or spraying white vinegar on the target plants. This may take more time than using a synthetic herbicide, but you can feel a little better about using these products.

You can also try to use wood chips to cover a certain area where you do not want anything to grow. This will not stop all the weeds, but the few that make it through can be easily picked by hand.

Who Is Most at Risk of Plant Poisoning?
Everyone should keep the following in mind to prevent being poisoned:
1
Do not eat any parts, nor contact with the sap of toxic or unknown plants;
2
If you need to kill it, wear long-sleeved shirts, pants and gloves with sharp tools to dig it out completely;
3
Clean the tools with rubbing alcohol or soap and water but do not do that with bare hands;
4
Clean your hands and skin once exposed to plants with soap and water;
5
Consider using barrier creams that contain bentoquatam to prevent poison oak, ivy and sumac rashes;
6
Dump it in special trash cans in sealed garbage packages;
7
Wear properly when you hiking or working in the wilderness. Long pants, long sleeves, gloves, hiking shoes, etc., that protect you from being hurt by any plants;
8
Once you or your family aren’t feeling well after eating, touching or inhaling anything from toxic plants, please call your doctor for help ASAP!
Outdoor Workers
Outdoor Workers and Recreationalists
Those who enjoy the outdoors either as a hobby or as part of their work will rarely see a plant and decide to munch on it (although the scenario is not unheard of). However, they do tend to deal with moving through and brushing aside plants. These people are more at risk of being poisoned by touching toxic plants than by ingesting them.
Outdoor Workers
Foragers
Foragers
Foraging for food and medicinal plants is a desirable skill among people who want to feel at one with the land. This hobby can be very useful and enjoyable, but if done wrong , it can lead to disastrous effects. People who forage are picking and grabbing plants with the full intention of using those plants, most of the time to ingest them.
Foragers
Children
Children
While outdoor workers are more likely to touch poison and foragers are more likely to ingest poison, children can easily do both. These bundles of joy just love to run around and explore the world. They enjoy touching things and occasionally shoving random stuff in their mouth; this is a terrible combination with toxic plants in the mix.
If you let your children run about, it is important to know what are the local toxic plants that they could accidentally get into. Try to educate the children and steer them away from where the toxic plants are located.

Common Toxic Houseplants
Common Toxic Houseplants
When it comes to decorating a house, there is nothing more refreshing than adding some beautiful houseplants. Some common house plants can also be toxic.

Aloe

aloe
Aloe is famous for its sunburn-soothing properties and its gorgeous desert design. However, many people do not realize that the latex the aloe vera plant produces can be mildly toxic to pets and children.

The latex contains a chemical compound known as saponin. Which when ingested, can cause vomiting, diarrhea, and low blood sugar. This, if left unchecked, can lead to dehydration and electrolyte imbalance. The proper response is to contact poison control or a veterinarian to know what to do in your particular circumstance if either your child or pet consumes aloe.

The latex of the plant is similar to the sap of the tree. It is inside the leaf, but sticks mainly toward the edges. If aloe gel is prepared properly it should be safe for use, but be sure to apply it only topically when treating burns.

Philodendron

Philodendron
Philodendron, also known as sweetheart vine, has become a resident at many houses and even businesses. They are glossy green and the leaves elegantly split, displaying interesting designs. Behind this beauty there is a needle-like toxin called calcium oxalate crystals.

These crystals are held within the plant and only affect you, your pets, or your loved ones if the plant tissue is broken. If ingested, the crystals can cause severe swelling, difficulty breathing, stomach pain, burning and pain. If they are accidentally caught on the skin, they can cause skin irritation.

If anyone accidentally ingests philodendron and they find it difficult to breathe or their tongue starts to swell up, it is important to seek medical attention immediately to avoid suffocation. If you have very young children or pets who have a tendency to tear at plants, keep them away from any philodendrons.

Peace Lily

Peace Lily
Peace lilies produce stunningly white flowers that bring to mind peace and serenity. This is one reason they are invited into our homes and given a place to stay. However, similar to philodendrons, the peace lily contains oxalate crystals known as raphides.

The raphides, once ingested, will cause swelling and burning sensations and can also cause skin irritation. Both pets and humans can get these symptoms so it is important to keep these plants from anyone who is likely to tear or chew it. Symptoms can become dire if the raphides cause the tongue and throat to swell to a point where the person or pet is having difficulty breathing. Seek proper medical attention if this is the case.

Snake Plant

Snake Plant
The snake plant is an interesting and popular house plant. Its stark architecture and wavy coloring has made it a fan favorite. This plant too, however, is toxic when ingested or if the sap touches your skin.

Snake plant sap will cause rashes if it comes into contact with your skin. In addition, it will cause diarrhea and vomiting when ingested. Again these symptoms are very serious and would be best avoided by keeping snake plants out of reach or by choosing a different houseplant.
Common Toxic Garden Plants
Common Toxic Garden Plants

Daffodil

Daffodil
Daffodils are a strikingly colorful flower. This can sometimes bring them much attention not from just onlooking adults but children as well. Since kids are more drawn to colorful objects, they may have a higher chance of just grabbing the flower and eating it. Adults have also been known to accidentally grab daffodil bulbs instead of onions.

Why are these mistakes so dangerous? Daffodils contain lycorine, which can induce nausea, vomiting, and diarrhea. It also contains oxalates which can cause swelling and pain. The symptoms can be worse in animals, because if your pets eat daffodils they may experience drowsiness, low blood pressure or even liver damage.

Make sure to call poison control when these symptoms set in. The vomiting and diarrhea have been known to go away after 3 hours, but it is better to be safe than sorry. Ingesting liquids to keep hydration up can be important. If the patient is having difficulty breathing, seek medical attention immediately.

Hydrangea

Hydrangea
Hydrangeas are unique, with their soft blue and pink flowers. They are a great addition to any garden, but should not be snacked on—not that you would want to. Hydrangeas can be especially nasty because they contain compounds known as glycosides. These will release hydrogen cyanide into the bloodstream when consumed. This will block your body’s ability to uptake oxygen to the cells in your body.

The way to combat this kind of poisoning is through getting IVs from the vet or doctor. It is important to contact your medical professional immediately since the symptoms can be fatal within minutes or hours.

Rhododendrons

Rhododendrons
Rhododendron, the state flower of Washington, is also toxic. The multitudinous, pink flowers can be quite dangerous. All parts of this plant are toxic, the leaves and seeds more so than the flowers. However, even the nectar of the flower is toxic and in the Mediterranean, where rhododendrons grow in more dense quantities, the honey from bees who gather rhododendron nectar can be poisonous.

Normally kids and pets do not eat enough to experience the full poisoning effect. However, just eating two leaves is enough to be considered dangerous. The grayanotoxin glycosides within the rhododendron can cause vomiting, diarrhea and irregular heartbeats. Things can get very serious when too much rhododendron is consumed and can lead to necessary medical intervention.

Start by calling poison control first if you suspect anyone has been munching on rhododendrons. The experts there will be able to help guide you through the necessary processes to cure your loved one.

Rhubarb

Rhubarb
Yummy rhubarb has a nasty side to it. While the stems are used in many recipes, including for rhubarb strawberry pie, the leaves are toxic. They contain oxalic acid which is known to blister the mouth, cause nausea, vomiting, diarrhea and kidney stones. The leaves are known to be more toxic to pets than humans, but in either case, it is important to contact poison control immediately to figure out necessary steps to cure the patient.
Common Toxic Weeds in the Yard
Common Toxic Weeds in the Yard

Bittersweet Nightshade

Bittersweet Nightshade
Nightshade is an invasive, noxious weed that is extremely poisonous. It has been found along the East and West Coast of the U.S. It makes its home in areas with disturbed soil. This could be near your garden or areas that have recently had bushes/trees put in.

These plants are dark green with purple flowers that develop into bright red berries. The whole plant is toxic and should be avoided by pets and children alike. If ingested it can cause nausea, vomiting, and diarrhea. The colorful berries are especially enticing to young children. If you see any plants that look similar to tomato or pepper plants that you did not plant in your yard, it is best to just pull them immediately.

Call poison control immediately if you think someone has fallen victim to nightshade.

Buttercups

Buttercups
Buttercups are found throughout the United States, especially in wet areas. The shiny, yellow flowers will pop up in the springtime, accompanying their dandelion friends. However, unlike dandelions, buttercups are not edible.

Buttercups will release a compound called protoanemonin. This toxin is known to cause vomiting, diarrhea, bloody stool, hypersalivation, depression, blisters, and more. These symptoms will affect both humans and animals. The sap may also cause irritation when it comes into contact with skin. These yellow flowers are dangerous and children should be observed cautiously when around them.

Foxgloves

Foxgloves
Foxgloves are beautiful plants that build towers out of vivid purple bell-shaped blossoms. They are very pretty to look at, but they contain a compound known as digoxin. This chemical is used in certain medicines to help people with certain heart conditions. However, the medicine is made by specialists, whereas someone eating foxgloves will receive unregulated amounts of the chemical.

This toxin can make you vomit and lower your heartbeat. This often causes dizziness and faintness. It is extremely important to call poison control immediately to know what to do in the case of foxglove poisoning. Some people have confused the young leaves of foxglove with borage, making adult foragers at risk as well as kids and pets.
How to Tend to or Get Rid of Toxic Plants
How to Tend to or Get Rid of Toxic Plants
Now that you know where to start with toxic plant identification, let us discuss how to either tend to the poisonous plants you decide to keep or get rid of them that plague your yard.

How to Tend to Poisonous Plants

Many plants that are toxic when ingested are also skin irritants. The philodendron is a good example of this. When the sap comes into contact with skin, it can cause a rash to form. To help protect yourself when tending to toxic plants, it is important to wear some sort of gloves.
Tend
Latex gloves may be the best solution due to their disposability. Regular gloves could potentially keep the poisonous sap on their surface. If the gloves aren’t cleaned then you could accidentally touch the irritant or pass it to someone else.

In addition you will want to plan where to keep your deadly beauties. If you have a toxic indoor plant try to keep it up high or out of reach of children and pets. This will keep accidents few and far between. Another idea is keeping your plants in areas that are usually inaccessible to children or pets. Areas such as an office, study room, or guest bedroom could be good locations. If applicable, you could also set up a terrarium for your little plant baby, making it more difficult for curious hands or paws to access.
tend2
If you plan to have outdoor plants, location will be key. You will want to put plants in an area that will be inaccessible to children, pets and even wild animals. You will probably want to avoid planting the plants in the front of your house if kids walk by on a regular basis, just to be cautious. Having the plants behind a fence will be best, but use your discretion when choosing a spot.

How to Get Rid of Poisonous Plants

plants
The easiest but possibly most controversial way to get rid of poisonous plants is by using herbicides. This can be especially easy if you own a grass lawn and use an herbicide that targets broadleaf (non-grass) species. You can find many herbicides meant for yard use by simply searching the term online. Once you have purchased the herbicide you will want to make sure to follow the label posted on the container. If you follow the instructions precisely, then everything should run smoothly for you.

If you don’t plan on using herbicides, there are a few organic methods you can use to try to get rid of toxic plants. You can manually pull the plants out of the ground. This is probably one of the most difficult methods because there is no assurance that you will get the whole plant out this way.

You can also try pouring boiling hot water or spraying white vinegar on the target plants. This may take more time than using a synthetic herbicide, but you can feel a little better about using these products.

You can also try to use wood chips to cover a certain area where you do not want anything to grow. This will not stop all the weeds, but the few that make it through can be easily picked by hand.

Common Problems

Is sweet wormwood invasive?

more more
Generally species from Artemisia genus are not invasive, except very few such as Common Mugwort (A. vulgaris) and Absinth Wormwood (A. absinthium) are considered to be invasive in the US. They spread slowly by rhizomes and herbicides can be applied to eradicate them.

Why has my sweet wormwood started to flop over?

more more
If grown in shade, it tends to flop over. Properly pruning the plant and keeping it under the full sun will prevent this problem. If shading is not the case, flopping over can happen after flowering and be prevented by shearing the plant during midsummer.

How to Water Sweet wormwood?

Cultivation:WaterDetail
Seedlings and young plants of sweet wormwood need regular watering. But once it matures, the plant becomes drought-tolerant, and no additional watering is required then. However, if the plant is cultivated in areas that are rainy or humid, you should pay attention to the drainage of the soil, as it may die back when the soil is soggy.

How to Fertilize Sweet wormwood?

Cultivation:FertilizerDetail
Sweet wormwood does not like rich soils, so it does not require any additional fertilizers. Over-fertilization may lead to leggy growth and look badly. Just use a little compost, manure or other organic fertilizers in spring or fall, then it will provide all the necessary nutrients for the plant.
close

Fertilizer

Sweet wormwood is grown for its attractive foliage. It does best when it is grown in a rich potting mix with a neutral pH level. If the soil is rich enough, it may not be necessary to provide any extra nutrients in the form of fertilizer. However, this plant can benefit from frequent, weak doses of fertilizer to keep leaves growing well. And, if you want your Sweet wormwood to produce move leaves, you will need to provide both sufficient fertilizer and a lot of moisture.
All plants need nutrients to grow, but some types are able to take what they need and don’t need any supplementation with fertilizers. Sweet wormwood, like other plants, use nutrients to support growth and all internal processes. Each of the main nutrients that plants use (nitrogen, phosphorus, and potassium) contribute to one or more of a plant’s essential functions, and in the case of foliage it is nitrogen that provides the most support. It can be difficult for a Sweet wormwood to get enough nitrogen from the soil , which is why many gardeners prefer to supplement by feeding Sweet wormwood with a source of nitrogen.
Sweet wormwood generally grows well, but a fertilizer can be applied about once a month to give the plant a boost when it is actively growing. You should fertilize Sweet wormwood about once a month only during the spring and summer months, but not during fall and winter when it becomes less active and does not use as many nutrients.You’ll know when to start fertilizing Sweet wormwood if you see signs of new growth. The fertilization schedule remains the same whether the plant is grown outside or indoors in a container. However, if your Sweet wormwood is in a container, you probably will not need to fertilize for the first one to two months. Potting soil made for container plants already contains plenty of nutrients, so you should only start to fertilize after your plant has been in the same soil for a while.
A balanced fertilizer works well for Sweet wormwood, for example an all-purpose fertilizer with a 10-10-10 NPK number. For natural fertilizers, blood meal or worm castings work well. You may also choose a fertilizer that is higher in nitrogen than other nutrients, such as fish fertilizer. Nitrogen provides support to leaves, which are the main feature that people want from Sweet wormwood. There is no point in providing a lot of supplements for flowers or seeds if that is not your purpose in growing the plant. Apply fertilizer based on the instructions on the particular type you have purchased. It is generally a good idea to start with half-strength fertilizer to avoid accidentally over-fertilizing your Sweet wormwood. Since this plant requires frequent fertilization, it is common to accidentally fertilize too much. Remember that it’s always easier to add more fertilizer than it is to try to save an over-fertilized plant. Don’t apply fertilizer to dry soil - it should already be at least somewhat moist before fertilizing. This helps the fertilizer absorb more easily and helps avoid fertilizer burn. You should also water after applying dry fertilizers to your soil.
Some fertilizers are meant to be mixed into the soil when planting, while others are applied on top of the soil and then watered in. For most types of Sweet wormwood, a water soluble fertilizer is an easy choice. Simply mix the fertilizer solution into your watering can at the recommended dosage for Sweet wormwood and then water the plant as usual. Slow-release granules or fertilizer spikes can also work well if you prefer not to remember to fertilize monthly.
Over-fertilization leads to a build-up of salts in the soil which leads to a lack of vitality overall and pale coloration in the leaves. Leaves may also wilt or develop brown tips as the excess salt from the fertilizer tries to make its way out of the leaves. Too much fertilizer makes it impossible for the plant to take up water and nutrients, which will eventually kill it if you don’t take steps to save your Sweet wormwood. If the Sweet wormwood is in a container, you could either remove it from the pot and repot it in fresh potting mix, or flush out the soil by running a lot of water through and letting it drain out thoroughly. If your Sweet wormwood is outdoors, the same theory applies, although it can be more difficult to flush outdoor soil. Water thoroughly and hold off on fertilizing again for a while. You may want to perform a soil test before you add any more fertilizer to make sure you don’t provide too much of any one nutrient.
Never fertilize your Sweet wormwood if it is not healthy, for example if it has developed a disease or has insect pests on it. Also do not fertilize a dehydrated plant, since the fertilizer will make this problem even worse. Only fertilize healthy plants. Do not splash fertilizer onto the leaves or stem of this plant when watering, since it can cause burned spots. Be careful not to allow the fertilizer to make direct contact with the plant, unless you are usually a special fertilizer designed to be applied to the foliage.

How to Prune Sweet wormwood?

Cultivation:PruningDetail
Pruning method is quite different for different species and cultivars. Generally, you can cut your Artemisia plants back to the base in fall or spring to encourage growth in the following year. While with evergreen or late-flowering species such as tree wormwood (Artemisia arborescens) and sweet wormwood (A. vallesiaca), pruning should be performed in early spring, when there is no danger of frost, but before the new growth starts. Remove wilt flowers as well as dead branches, and leave only new shoots.
If the plant is not pruned, it can get really tall (1.5 to 1.8 m). Trimming some terminal leaves and branches in summer, can return the plants that grow wild into a more favorable shape. If the plants get very bushy and thick, the air between the leaves will become more humid – favorable for powdery and downy mildew to develop. Thinning out the plants a little bit to improve the airflow and prevent these diseases. More intensive thinning is necessary if the plants are grown in very humid climates.
Besides, it is very important to wear gloves while pruning sweet wormwood because its repelling chemicals can also irritate the skin.

What Soil is Best for Sweet wormwood?

Cultivation:SoilDetail
Sweet wormwood does not have any specific requirements when it comes to soil structure and pH, but they will not develop well in very rich and heavy soils. It is best if the soil is poor to moderately fertile and well-drained with a small to moderate amount of moisture.
Cultivation:PropagationDetail

How to Propagate Sweet wormwood?

Cultivation:PropagationDetail
Sweet wormwood can be propagated by seeds (some annual Artemisia species are self-sown) or cuttings. Propagation by cuttings includes taking 8 to 10 cm cuttings in late summer and rooting them in a loose, sandy compost or perlite. It is best if the rooting powder is applied before putting the cutting into the medium. Spray water every couple of days to keep it moist.
After a week or two, the cuttings will root. When the roots start protruding from the medium, it is time for a transplant. Rooted cuttings can be put into a separate container or planted directly into the soil in the garden. The distance between the cuttings should be at least 38 cm.
close

Propagation

Only sow Sweet wormwood seeds in warm weather, preferably during the later weeks of spring after any danger of frost or dropping temperatures has passed. Even in warm climates, ensure the soil is sufficiently warm, as cooler soil can hinder germination and growth. If you want to sow the seeds earlier, you need to do it indoors for successful germination.
To sow Sweet wormwood in your growing medium, you don't need many extra tools. Simply put on your gardening gloves and get started!
What you will need:
  • Healthy and full seeds, as the germination rate of such seeds will be higher.
  • Growing medium with potting mix soil, divided into rows.
  • Fertilizer or compost.
  • (Optional) A dibbler or stake.
  • A spray bottle to hydrate the soil.
  • (Optional) A piece of plastic film.
Steps:
  1. Prepare the soil: Mix the soil with organic fertilizer. Fully rotted fertilizer is recommended, and its volume should not exceed one quarter of the soil volume when mixing.
  2. Sow the seeds: Sprinkle the seeds onto the soil and cover them afterwards. Alternatively, use a dibbler or stake to pre-dig holes for the seeds, placing about 3 seeds in each mound. The depth of the soil covering the seeds should be about five times the thickness of the seed.
  3. Space the seeds: Leave a 4-6-inch gap between each seed mound.
  4. Water the soil: After planting, water the soil in the container well to provide enough moisture for the seeds to germinate.
  5. Mulch and maintain: Mulch the surface of the container soil to retain moisture and promote seed germination. Use a spray bottle to moisten the soil when it becomes relatively dry. Continue this until the seeds germinate.
Note: Before seeds germinate, they can be kept in a low-light location. However, after germination, it's important to provide adequate light to the plant to prevent excessive growth.

How to Plant Sweet wormwood?

Cultivation:PlantingDetail
You can easily purchase the seeds or seedlings of sweet wormwood from a nearby gardening store. Choose a sunny location with soil that is poor to moderately fertile and well-drained. Simply sow the seeds or plant the seedlings where optimum for them in spring or fall. If you grow sweet wormwood in containers, place the pot onto a sunny windowsill.
As contains compounds that provide a good defense against insects and herbivores, sweet wormwood can inhibit the growth of edible plants nearby when these chemicals leach into the soil. It is advised to plant sweet wormwood amongst other species in your garden to protect them. If sweet wormwood is used as a natural pest repellent, it is necessary to properly isolate it from other plants by planting it into a separate container or at a safe distance (the stem should be at least 1.2 to 1.5 m away from the nearest plants).

Seasonal Precautions

Covering the soil beneath sweet wormwood with mulch can protect it from soil frost. If the winter is dry, the plant may need some additional water, especially the evergreen species. If the plant is grown in colder climates, it is advised to grow it in containers and put it inside during the winter.
During the blooming season, sweet wormwood produces a lot of pollen, which can cause very negative effects on people with allergies. So cutting the flower buds before blooming can save you from sneezing and running nose. However, you then will miss the enjoyment of the blooms of sweet wormwood.

Leaf rot
Leaf rot Leaf rot Leaf rot
This pathogen can cause the leaves to rot.
Solutions: Bacterial infections need to be treated quickly to prevent the spread to neighboring, healthy plants, potentially wiping out large sections of your indoor or outdoor garden. In mild cases: Use sterilized (10% bleach solution) pruning shears or scissors to remove any infected plant parts, making sure to dispose of them off site. Use a copper-based bactericide to treat the unaffected foliage, as well as the soil, and neighboring plants. Follow the manufacturer’s rate and timing directions found on the product label. In severe cases, where more than half the leaves are affected: Remove all of the infected plants from the garden, disposing of them off site. Treat the soil and neighboring plants using a copper-based bactericide. Follow the manufacturer’s rate and timing directions found on the product label.

Thrips
Thrips Thrips Thrips
Thrips are 1 to 2 mm bugs with slender black or translucent-yellow bodies. They move quickly and feed on the plant's sap.
Solutions: Thrips can be controlled in several ways. Spray plants with Pyrethrin, which is an organic pesticide derived from marigolds (follow label instructions) or Permethrin, the synthetic version of Pyrethrin. Introduce beneficial insects to the garden that eat thrips, such as minute pirate bugs and green lacewings. Remove heavily infested plants from the area and discard. Address viral diseases that may have been transmitted by the pests. For less serious cases -use a hose to spray the thrips off of the plants.

Nutrient deficiencies
Nutrient deficiencies Nutrient deficiencies Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Solutions: There are several easy ways to remedy the nutrient deficiencies in soils. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.

Leaf beetles
Leaf beetles Leaf beetles Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.

Leaf rot
This pathogen can cause the leaves to rot.
Overview
Overview
Leaf rot is very common among both house plants and garden plants. It affects foliage and occurs mainly when the leaves become wet due to rain or misting by the gardener. The cause is fungal disease and this is facilitated by the fungal spores adhering to wet leaves then penetrating the leaf and expanding rapidly. Damp conditions and poor air circulation will increase chances of infection taking place. Another factor are leaves that are damaged or have been penetrated by sap sucking insects that facilitate plant penetration.
Symptom Analysis
Symptom Analysis
  1. Spores are able to cling to a damp leaf and penetrate, often through an existing wound.
  2. A small dark brown mark appears which expands rapidly as sporulation starts to take place.
  3. Quite quickly these bull's eye like circles can link together and the whole leaf turns dark and loses texture.
  4. Leaf drop occurs.
Disease Cause
Disease Cause
These symptoms are caused by a bacterial infection invading the plant. Bacteria from many sources in the environment (air, water, soil, diseased plants) enter a plant through wounds, or in some cases the stomata when they are open. Once inside the leaf tissue, the bacteria feed and reproduce quickly, breaking down healthy leaves.
Bacterial infections threaten most plant species, and are more prominent in wet weather that more easily transfers the bacteria from plant to plant, or from soil to plant.
Solutions
Solutions
Bacterial infections need to be treated quickly to prevent the spread to neighboring, healthy plants, potentially wiping out large sections of your indoor or outdoor garden.
In mild cases: Use sterilized (10% bleach solution) pruning shears or scissors to remove any infected plant parts, making sure to dispose of them off site. Use a copper-based bactericide to treat the unaffected foliage, as well as the soil, and neighboring plants. Follow the manufacturer’s rate and timing directions found on the product label.
In severe cases, where more than half the leaves are affected: Remove all of the infected plants from the garden, disposing of them off site. Treat the soil and neighboring plants using a copper-based bactericide. Follow the manufacturer’s rate and timing directions found on the product label.
Prevention
Prevention
  1. Clean up garden debris at the end of the season, especially if it contains any diseased plant tissue. Diseases can overwinter from season to season and infect new plants.
  2. Avoid overhead watering to prevent transferring pathogens from one plant to another, and to keep foliage dry.
  3. Mulch around the base of plants to prevent soil-borne bacteria from splashing up onto uninfected plants.
  4. Sterilize cutting tools using a 10% bleach solution when gardening and moving from one plant to another.
  5. Do not work in your garden when it is wet.
  6. Rotate crops to prevent the buildup of bacteria in one site due to continuous cropping.
  7. Use a copper or streptomycin-containing bactericide in early spring to prevent infection. Read label directions carefully as they are not suitable for all plants.
  8. Ensure plants are well spaced and thin leaves on densely leaved plants so that air circulation is maximised.

Thrips
plant poor
Thrips
Thrips are 1 to 2 mm bugs with slender black or translucent-yellow bodies. They move quickly and feed on the plant's sap.
Overview
Overview
Thrips are tiny, flying, sap-sucking insects that attack the tender parts of plants, causing scarring and weakening of the plant and sometimes, if the infestation is severe enough, plant death. They have undersized double wings with a fringe on them, resembling tiny, misshapen damselflies. Thrips have a taste for many houseplants and crops, making them a serious nuisance.
They appear in early spring after the last frost has occurred. If not controlled in early spring, they will persist for most of the season. They are often attracted to weakened plants, such as those struck by drought/underwatering or malnutrition. Excessive use of nitrogen fertilizer also seems to attract them to a plant. Thrips can spread various viruses between plants, leading to more serious damage.
Symptom Analysis
Symptom Analysis
Thrips are so small that they may not be noticed (1 to 2 mm long), but infested plants present several key signs. Tiny pale spots appear on leaves, which may start to deform, show white or silver discoloration, or become papery in texture.
Flower petals may be damaged as well, and might display color break, which is dark or pale discoloring of petal tissue damaged before the buds had a chance to open. Fruits may show scabby or silvery scarring. Tiny black spots of the insects' excrement may be visible.
As the infestation progresses, infested terminals roll and become discolored, and leaves may drop prematurely. The plant's growth may be stunted. Secondary viral and bacterial infections, which thrips can transmit, may become evident.
The good news? Thrips rarely kill or seriously weaken shrubs and trees. Smaller plants, such as vegetable crops and herbaceous ornamentals, tend to be more severely affected.
Solutions
Solutions
Thrips can be controlled in several ways.
  • Spray plants with Pyrethrin, which is an organic pesticide derived from marigolds (follow label instructions) or Permethrin, the synthetic version of Pyrethrin.
  • Introduce beneficial insects to the garden that eat thrips, such as minute pirate bugs and green lacewings.
  • Remove heavily infested plants from the area and discard.
  • Address viral diseases that may have been transmitted by the pests.
  • For less serious cases -use a hose to spray the thrips off of the plants.
Prevention
Prevention
The best way to protect plants from thrips is to take preventative measures.
  • Avoid buying and transplanting infected plants. Check for signs of thrip damage before buying.
  • Regularly prune off dead branches and leaves.
  • Keep the garden weeded and remove debris such as dead branches and leaves.
  • Avoid unnecessary use of insecticides as they can kill predatory insects that keep thrips in check.
  • Plant a diverse variety of plants in the garden to provide habitat for predatory insects.

Nutrient deficiencies
plant poor
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Overview
Overview
Nutrient deficiencies can be seen in many different ways on plants. Basically, the lack of nutrients will inhibit plant growth, produce weak stems and leaves, and leave plants open to infection from pests and diseases. Plants use the nutrients from the soil to help them with photosynthesis. This, in turn, produces healthy plant growth. Plants that lack adequate amounts of nutrients will look lackluster and unhealthy. Eventually, if this is not addressed, it will cause the plants to die. The most important nutrients that plants need are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Additionally, plants require small amounts of micronutrients such as iron, boron, manganese, zinc, copper, and molybdenum.
Symptom Analysis
Symptom Analysis
A common sign that plants are experiencing nutrient deficiencies is the yellowing of leaves. This may be an overall yellowing or leaves that are yellow but still have green veins. These leaves will eventually brown off and die.
Another sign is the loss of plant vigor. The plants may not be growing as well as they should or their growth may be stunted.
Below are some common symptoms that appear when plants are lacking in nutrients.
Nitrogen (N): Inner, older leaves yellow first. If the deficiency is severe, yellowing progresses outward to newer growth.
Potassium (K): Leaf edges may turn brown and crinkly, with a yellowing layer forming just inside of the edge. Older leaves tend to be impacted first.
Phosphorus (P): Lack of vigorous growth. Plants will appear stunted.
Zinc (Zn): Yellowing tends to occur first at the base of the leaf.
Copper (Cu): Newer leaves begin to yellow first, with older leaves yellowing only if the deficiency becomes severe.
Boron (B): Newer leaves are impacted first. Foliage may also become particularly brittle in cases of boron deficiency.
Disease Cause
Disease Cause
There are several factors that can lead to nutrient deficiencies, a situation where plants are not receiving the nutrients that they need. This could be because they are planted in nutrient-deficient soils, or that the soil's pH is too high or low. Incorrect soil pH can lock up certain nutrients, thus making them unavailable to plants. Lack of soil moisture can also be a problem, because plants need water to be able to absorb the nutrients from the soil.
Solutions
Solutions
There are several easy ways to remedy the nutrient deficiencies in soils.
  1. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies.
  2. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy.

Prevention
Prevention
There are several easy ways to prevent nutrient deficiencies in plants.
  1. Regular fertilizing. Regular addition of fertilizer to the soil is one of the simplest and most effective ways to prevent deficiencies.
  2. Proper watering. Both over and under watering can adversely impact a plant's roots, which in turn makes it harder for them to properly take up nutrients.
  3. Testing the soil's pH. A soil's acidity or alkalinity will impact the degree to which certain nutrients are available to be taken up by plants. Knowing the soil's pH means it can be amended to suit the needs of the individual plants.

Leaf beetles
plant poor
Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Overview
Overview
Leaf beetles range in size from 1.5 mm to 2 cm. Both adult beetles and their larvae eat the leaves of many different types of plants. There are over 35,000 different species of leaf beetles, in a variety of colors including gold, green, yellow-striped, and red striped. Some of these have been mistaken for ladybirds because of their shape and coloring. They can be oval, round, or elongated in shape. These insect pests are most active in spring and summer.
If not controlled, leaf beetles can do a lot of damage to vegetable crops and ornamental plants. They feed on the leaves, flowers, stems, roots, and fruits of different plants. They can fly, which means it's easy for them to move from one plant to another. Some species of leaf beetles only target one specific crop, while others will target many different types of plants. Although a lot of the damage that they cause is cosmetic, an infestation can weaken a plant and leave it prone to other more problematic diseases.
Symptom Analysis
Symptom Analysis
The first signs of a leaf beetles infestation are small visible holes in leaves. Leaves then become discolored and dark beetle droppings can be seen. As the leaves turn yellow and brown, they will drop off the plant onto the ground. Some leaves will appear skeletonized with only the veins still remaining.
Infestation begins in spring, when the adult beetles emerge from the soil and lay their eggs on the leaves of plants. When these eggs hatch, the young nymphs start munching on the leaves as they grow up. Once leaf beetles are large and mature, they'll fall to the ground and pupate in the soil over winter before starting the cycle all over again.
Leaf beetles also eat holes in fruits and vegetables. These can be seen as small round holes that sometimes have a larger brown area surrounding them.
Solutions
Solutions
For less serious cases:
  1. Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread.
To treat more serious infestations:
  1. Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions.
  2. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.
Prevention
Prevention
To prevent infestations of leaf beetles, follow these practices.
  1. Regularly check for beetles. To prevent large pest infestations, be proactive about frequently checking plants for pests and removing them quickly.
  2. Clear debris. Clear weeds and debris to remove areas where these beetles may overwinter and hide.
  3. Attract natural predators. Birds and other insects, such as wasps and ladybugs, are effective natural predators of leaf beetles. Encourage them to visit by including a diverse array of plants to provide habitat and food. Also, avoid applying broad-spectrum herbicides that can harm and kill beneficial insects.
  4. Plant aromatic herbs like mint, garlic, or rosemary, as these can repel leaf beetles.

Sweet Wormwood and Their Toxicity

* The judgment on toxicity and danger is for reference only. We DO NOT GUARANTEE any accuracy of such judgment. Therefore, you SHALL NOT rely on such judgment. It is IMPORTANT TO SEEK PROFESSIONAL ADVICE in advance when necessary.
Slightly Toxic to Humans
Sweet wormwood's toxic ingredient is known as thujone and is present in all parts, especially the leaves. Thujone affects the brain, kidney, liver, and uterus. It can cause muscle spasms and convulsions, memory problems, hallucinations, miscarriage, kidney and liver damage or failure, or death in high enough doses. Humans are strongly affected by thujone, and children, people with cognitive issues, and intoxication-seekers should be kept away from all wormwood species. Further warning signs include jaundice, dark, profuse urine, depression, behavior changes, weakness, nausea, dizziness, and loss of consciousness.

Pets
Some pets are less likely than children to eat and touch just about everything. This is good, as a pet owner. However, you know your pet best, and it is up to you to keep them safe. There are plenty of poisonous weeds that can grow within the confines of your lawn, which might make your dogs or cats ill or worse if they eat them. Try to have an idea of what toxic plants grow in your area and keep them under control and your pets away from them.

Common Toxic Houseplants
Common Toxic Houseplants
When it comes to decorating a house, there is nothing more refreshing than adding some beautiful houseplants. Some common house plants can also be toxic.

Aloe

aloe
Aloe is famous for its sunburn-soothing properties and its gorgeous desert design. However, many people do not realize that the latex the aloe vera plant produces can be mildly toxic to pets and children.

The latex contains a chemical compound known as saponin. Which when ingested, can cause vomiting, diarrhea, and low blood sugar. This, if left unchecked, can lead to dehydration and electrolyte imbalance. The proper response is to contact poison control or a veterinarian to know what to do in your particular circumstance if either your child or pet consumes aloe.

The latex of the plant is similar to the sap of the tree. It is inside the leaf, but sticks mainly toward the edges. If aloe gel is prepared properly it should be safe for use, but be sure to apply it only topically when treating burns.

Philodendron

Philodendron
Philodendron, also known as sweetheart vine, has become a resident at many houses and even businesses. They are glossy green and the leaves elegantly split, displaying interesting designs. Behind this beauty there is a needle-like toxin called calcium oxalate crystals.

These crystals are held within the plant and only affect you, your pets, or your loved ones if the plant tissue is broken. If ingested, the crystals can cause severe swelling, difficulty breathing, stomach pain, burning and pain. If they are accidentally caught on the skin, they can cause skin irritation.

If anyone accidentally ingests philodendron and they find it difficult to breathe or their tongue starts to swell up, it is important to seek medical attention immediately to avoid suffocation. If you have very young children or pets who have a tendency to tear at plants, keep them away from any philodendrons.

Peace Lily

Peace Lily
Peace lilies produce stunningly white flowers that bring to mind peace and serenity. This is one reason they are invited into our homes and given a place to stay. However, similar to philodendrons, the peace lily contains oxalate crystals known as raphides.

The raphides, once ingested, will cause swelling and burning sensations and can also cause skin irritation. Both pets and humans can get these symptoms so it is important to keep these plants from anyone who is likely to tear or chew it. Symptoms can become dire if the raphides cause the tongue and throat to swell to a point where the person or pet is having difficulty breathing. Seek proper medical attention if this is the case.

Snake Plant

Snake Plant
The snake plant is an interesting and popular house plant. Its stark architecture and wavy coloring has made it a fan favorite. This plant too, however, is toxic when ingested or if the sap touches your skin.

Snake plant sap will cause rashes if it comes into contact with your skin. In addition, it will cause diarrhea and vomiting when ingested. Again these symptoms are very serious and would be best avoided by keeping snake plants out of reach or by choosing a different houseplant.
Common Toxic Garden Plants
Common Toxic Garden Plants

Daffodil

Daffodil
Daffodils are a strikingly colorful flower. This can sometimes bring them much attention not from just onlooking adults but children as well. Since kids are more drawn to colorful objects, they may have a higher chance of just grabbing the flower and eating it. Adults have also been known to accidentally grab daffodil bulbs instead of onions.

Why are these mistakes so dangerous? Daffodils contain lycorine, which can induce nausea, vomiting, and diarrhea. It also contains oxalates which can cause swelling and pain. The symptoms can be worse in animals, because if your pets eat daffodils they may experience drowsiness, low blood pressure or even liver damage.

Make sure to call poison control when these symptoms set in. The vomiting and diarrhea have been known to go away after 3 hours, but it is better to be safe than sorry. Ingesting liquids to keep hydration up can be important. If the patient is having difficulty breathing, seek medical attention immediately.

Hydrangea

Hydrangea
Hydrangeas are unique, with their soft blue and pink flowers. They are a great addition to any garden, but should not be snacked on—not that you would want to. Hydrangeas can be especially nasty because they contain compounds known as glycosides. These will release hydrogen cyanide into the bloodstream when consumed. This will block your body’s ability to uptake oxygen to the cells in your body.

The way to combat this kind of poisoning is through getting IVs from the vet or doctor. It is important to contact your medical professional immediately since the symptoms can be fatal within minutes or hours.

Rhododendrons

Rhododendrons
Rhododendron, the state flower of Washington, is also toxic. The multitudinous, pink flowers can be quite dangerous. All parts of this plant are toxic, the leaves and seeds more so than the flowers. However, even the nectar of the flower is toxic and in the Mediterranean, where rhododendrons grow in more dense quantities, the honey from bees who gather rhododendron nectar can be poisonous.

Normally kids and pets do not eat enough to experience the full poisoning effect. However, just eating two leaves is enough to be considered dangerous. The grayanotoxin glycosides within the rhododendron can cause vomiting, diarrhea and irregular heartbeats. Things can get very serious when too much rhododendron is consumed and can lead to necessary medical intervention.

Start by calling poison control first if you suspect anyone has been munching on rhododendrons. The experts there will be able to help guide you through the necessary processes to cure your loved one.

Rhubarb

Rhubarb
Yummy rhubarb has a nasty side to it. While the stems are used in many recipes, including for rhubarb strawberry pie, the leaves are toxic. They contain oxalic acid which is known to blister the mouth, cause nausea, vomiting, diarrhea and kidney stones. The leaves are known to be more toxic to pets than humans, but in either case, it is important to contact poison control immediately to figure out necessary steps to cure the patient.
Common Toxic Weeds in the Yard
Common Toxic Weeds in the Yard

Bittersweet Nightshade

Bittersweet Nightshade
Nightshade is an invasive, noxious weed that is extremely poisonous. It has been found along the East and West Coast of the U.S. It makes its home in areas with disturbed soil. This could be near your garden or areas that have recently had bushes/trees put in.

These plants are dark green with purple flowers that develop into bright red berries. The whole plant is toxic and should be avoided by pets and children alike. If ingested it can cause nausea, vomiting, and diarrhea. The colorful berries are especially enticing to young children. If you see any plants that look similar to tomato or pepper plants that you did not plant in your yard, it is best to just pull them immediately.

Call poison control immediately if you think someone has fallen victim to nightshade.

Buttercups

Buttercups
Buttercups are found throughout the United States, especially in wet areas. The shiny, yellow flowers will pop up in the springtime, accompanying their dandelion friends. However, unlike dandelions, buttercups are not edible.

Buttercups will release a compound called protoanemonin. This toxin is known to cause vomiting, diarrhea, bloody stool, hypersalivation, depression, blisters, and more. These symptoms will affect both humans and animals. The sap may also cause irritation when it comes into contact with skin. These yellow flowers are dangerous and children should be observed cautiously when around them.

Foxgloves

Foxgloves
Foxgloves are beautiful plants that build towers out of vivid purple bell-shaped blossoms. They are very pretty to look at, but they contain a compound known as digoxin. This chemical is used in certain medicines to help people with certain heart conditions. However, the medicine is made by specialists, whereas someone eating foxgloves will receive unregulated amounts of the chemical.

This toxin can make you vomit and lower your heartbeat. This often causes dizziness and faintness. It is extremely important to call poison control immediately to know what to do in the case of foxglove poisoning. Some people have confused the young leaves of foxglove with borage, making adult foragers at risk as well as kids and pets.
How to Tend to or Get Rid of Toxic Plants
How to Tend to or Get Rid of Toxic Plants
Now that you know where to start with toxic plant identification, let us discuss how to either tend to the poisonous plants you decide to keep or get rid of them that plague your yard.

How to Tend to Poisonous Plants

Many plants that are toxic when ingested are also skin irritants. The philodendron is a good example of this. When the sap comes into contact with skin, it can cause a rash to form. To help protect yourself when tending to toxic plants, it is important to wear some sort of gloves.
Tend
Latex gloves may be the best solution due to their disposability. Regular gloves could potentially keep the poisonous sap on their surface. If the gloves aren’t cleaned then you could accidentally touch the irritant or pass it to someone else.

In addition you will want to plan where to keep your deadly beauties. If you have a toxic indoor plant try to keep it up high or out of reach of children and pets. This will keep accidents few and far between. Another idea is keeping your plants in areas that are usually inaccessible to children or pets. Areas such as an office, study room, or guest bedroom could be good locations. If applicable, you could also set up a terrarium for your little plant baby, making it more difficult for curious hands or paws to access.
tend2
If you plan to have outdoor plants, location will be key. You will want to put plants in an area that will be inaccessible to children, pets and even wild animals. You will probably want to avoid planting the plants in the front of your house if kids walk by on a regular basis, just to be cautious. Having the plants behind a fence will be best, but use your discretion when choosing a spot.

How to Get Rid of Poisonous Plants

plants
The easiest but possibly most controversial way to get rid of poisonous plants is by using herbicides. This can be especially easy if you own a grass lawn and use an herbicide that targets broadleaf (non-grass) species. You can find many herbicides meant for yard use by simply searching the term online. Once you have purchased the herbicide you will want to make sure to follow the label posted on the container. If you follow the instructions precisely, then everything should run smoothly for you.

If you don’t plan on using herbicides, there are a few organic methods you can use to try to get rid of toxic plants. You can manually pull the plants out of the ground. This is probably one of the most difficult methods because there is no assurance that you will get the whole plant out this way.

You can also try pouring boiling hot water or spraying white vinegar on the target plants. This may take more time than using a synthetic herbicide, but you can feel a little better about using these products.

You can also try to use wood chips to cover a certain area where you do not want anything to grow. This will not stop all the weeds, but the few that make it through can be easily picked by hand.

7
Wear properly when you hiking or working in the wilderness. Long pants, long sleeves, gloves, hiking shoes, etc., that protect you from being hurt by any plants;
8
Once you or your family aren’t feeling well after eating, touching or inhaling anything from toxic plants, please call your doctor for help ASAP!
Outdoor Workers
Outdoor Workers and Recreationalists
Those who enjoy the outdoors either as a hobby or as part of their work will rarely see a plant and decide to munch on it (although the scenario is not unheard of). However, they do tend to deal with moving through and brushing aside plants. These people are more at risk of being poisoned by touching toxic plants than by ingesting them.
Outdoor Workers
Foragers
Foragers
Foraging for food and medicinal plants is a desirable skill among people who want to feel at one with the land. This hobby can be very useful and enjoyable, but if done wrong , it can lead to disastrous effects. People who forage are picking and grabbing plants with the full intention of using those plants, most of the time to ingest them.
Foragers
Children
Children
While outdoor workers are more likely to touch poison and foragers are more likely to ingest poison, children can easily do both. These bundles of joy just love to run around and explore the world. They enjoy touching things and occasionally shoving random stuff in their mouth; this is a terrible combination with toxic plants in the mix.
If you let your children run about, it is important to know what are the local toxic plants that they could accidentally get into. Try to educate the children and steer them away from where the toxic plants are located.

These crystals are held within the plant and only affect you, your pets, or your loved ones if the plant tissue is broken. If ingested, the crystals can cause severe swelling, difficulty breathing, stomach pain, burning and pain. If they are accidentally caught on the skin, they can cause skin irritation.

If anyone accidentally ingests philodendron and they find it difficult to breathe or their tongue starts to swell up, it is important to seek medical attention immediately to avoid suffocation. If you have very young children or pets who have a tendency to tear at plants, keep them away from any philodendrons.

Peace Lily

Peace Lily
Peace lilies produce stunningly white flowers that bring to mind peace and serenity. This is one reason they are invited into our homes and given a place to stay. However, similar to philodendrons, the peace lily contains oxalate crystals known as raphides.

The raphides, once ingested, will cause swelling and burning sensations and can also cause skin irritation. Both pets and humans can get these symptoms so it is important to keep these plants from anyone who is likely to tear or chew it. Symptoms can become dire if the raphides cause the tongue and throat to swell to a point where the person or pet is having difficulty breathing. Seek proper medical attention if this is the case.

Snake Plant

Snake Plant
The snake plant is an interesting and popular house plant. Its stark architecture and wavy coloring has made it a fan favorite. This plant too, however, is toxic when ingested or if the sap touches your skin.

Snake plant sap will cause rashes if it comes into contact with your skin. In addition, it will cause diarrhea and vomiting when ingested. Again these symptoms are very serious and would be best avoided by keeping snake plants out of reach or by choosing a different houseplant.
Common Toxic Garden Plants
Common Toxic Garden Plants

Daffodil

Daffodil
Daffodils are a strikingly colorful flower. This can sometimes bring them much attention not from just onlooking adults but children as well. Since kids are more drawn to colorful objects, they may have a higher chance of just grabbing the flower and eating it. Adults have also been known to accidentally grab daffodil bulbs instead of onions.

Why are these mistakes so dangerous? Daffodils contain lycorine, which can induce nausea, vomiting, and diarrhea. It also contains oxalates which can cause swelling and pain. The symptoms can be worse in animals, because if your pets eat daffodils they may experience drowsiness, low blood pressure or even liver damage.

Make sure to call poison control when these symptoms set in. The vomiting and diarrhea have been known to go away after 3 hours, but it is better to be safe than sorry. Ingesting liquids to keep hydration up can be important. If the patient is having difficulty breathing, seek medical attention immediately.

Hydrangea

Hydrangea
Hydrangeas are unique, with their soft blue and pink flowers. They are a great addition to any garden, but should not be snacked on—not that you would want to. Hydrangeas can be especially nasty because they contain compounds known as glycosides. These will release hydrogen cyanide into the bloodstream when consumed. This will block your body’s ability to uptake oxygen to the cells in your body.

The way to combat this kind of poisoning is through getting IVs from the vet or doctor. It is important to contact your medical professional immediately since the symptoms can be fatal within minutes or hours.

Rhododendrons

Rhododendrons
Rhododendron, the state flower of Washington, is also toxic. The multitudinous, pink flowers can be quite dangerous. All parts of this plant are toxic, the leaves and seeds more so than the flowers. However, even the nectar of the flower is toxic and in the Mediterranean, where rhododendrons grow in more dense quantities, the honey from bees who gather rhododendron nectar can be poisonous.

Normally kids and pets do not eat enough to experience the full poisoning effect. However, just eating two leaves is enough to be considered dangerous. The grayanotoxin glycosides within the rhododendron can cause vomiting, diarrhea and irregular heartbeats. Things can get very serious when too much rhododendron is consumed and can lead to necessary medical intervention.

Start by calling poison control first if you suspect anyone has been munching on rhododendrons. The experts there will be able to help guide you through the necessary processes to cure your loved one.

Rhubarb

Rhubarb
Yummy rhubarb has a nasty side to it. While the stems are used in many recipes, including for rhubarb strawberry pie, the leaves are toxic. They contain oxalic acid which is known to blister the mouth, cause nausea, vomiting, diarrhea and kidney stones. The leaves are known to be more toxic to pets than humans, but in either case, it is important to contact poison control immediately to figure out necessary steps to cure the patient.
Common Toxic Weeds in the Yard
Common Toxic Weeds in the Yard

Bittersweet Nightshade

Bittersweet Nightshade
Nightshade is an invasive, noxious weed that is extremely poisonous. It has been found along the East and West Coast of the U.S. It makes its home in areas with disturbed soil. This could be near your garden or areas that have recently had bushes/trees put in.

These plants are dark green with purple flowers that develop into bright red berries. The whole plant is toxic and should be avoided by pets and children alike. If ingested it can cause nausea, vomiting, and diarrhea. The colorful berries are especially enticing to young children. If you see any plants that look similar to tomato or pepper plants that you did not plant in your yard, it is best to just pull them immediately.

Call poison control immediately if you think someone has fallen victim to nightshade.

Buttercups

Buttercups
Buttercups are found throughout the United States, especially in wet areas. The shiny, yellow flowers will pop up in the springtime, accompanying their dandelion friends. However, unlike dandelions, buttercups are not edible.

Buttercups will release a compound called protoanemonin. This toxin is known to cause vomiting, diarrhea, bloody stool, hypersalivation, depression, blisters, and more. These symptoms will affect both humans and animals. The sap may also cause irritation when it comes into contact with skin. These yellow flowers are dangerous and children should be observed cautiously when around them.

Foxgloves

Foxgloves
Foxgloves are beautiful plants that build towers out of vivid purple bell-shaped blossoms. They are very pretty to look at, but they contain a compound known as digoxin. This chemical is used in certain medicines to help people with certain heart conditions. However, the medicine is made by specialists, whereas someone eating foxgloves will receive unregulated amounts of the chemical.

This toxin can make you vomit and lower your heartbeat. This often causes dizziness and faintness. It is extremely important to call poison control immediately to know what to do in the case of foxglove poisoning. Some people have confused the young leaves of foxglove with borage, making adult foragers at risk as well as kids and pets.
How to Tend to or Get Rid of Toxic Plants
How to Tend to or Get Rid of Toxic Plants
Now that you know where to start with toxic plant identification, let us discuss how to either tend to the poisonous plants you decide to keep or get rid of them that plague your yard.

How to Tend to Poisonous Plants

Many plants that are toxic when ingested are also skin irritants. The philodendron is a good example of this. When the sap comes into contact with skin, it can cause a rash to form. To help protect yourself when tending to toxic plants, it is important to wear some sort of gloves.
Tend
Latex gloves may be the best solution due to their disposability. Regular gloves could potentially keep the poisonous sap on their surface. If the gloves aren’t cleaned then you could accidentally touch the irritant or pass it to someone else.

In addition you will want to plan where to keep your deadly beauties. If you have a toxic indoor plant try to keep it up high or out of reach of children and pets. This will keep accidents few and far between. Another idea is keeping your plants in areas that are usually inaccessible to children or pets. Areas such as an office, study room, or guest bedroom could be good locations. If applicable, you could also set up a terrarium for your little plant baby, making it more difficult for curious hands or paws to access.
tend2
If you plan to have outdoor plants, location will be key. You will want to put plants in an area that will be inaccessible to children, pets and even wild animals. You will probably want to avoid planting the plants in the front of your house if kids walk by on a regular basis, just to be cautious. Having the plants behind a fence will be best, but use your discretion when choosing a spot.

How to Get Rid of Poisonous Plants

plants
The easiest but possibly most controversial way to get rid of poisonous plants is by using herbicides. This can be especially easy if you own a grass lawn and use an herbicide that targets broadleaf (non-grass) species. You can find many herbicides meant for yard use by simply searching the term online. Once you have purchased the herbicide you will want to make sure to follow the label posted on the container. If you follow the instructions precisely, then everything should run smoothly for you.

If you don’t plan on using herbicides, there are a few organic methods you can use to try to get rid of toxic plants. You can manually pull the plants out of the ground. This is probably one of the most difficult methods because there is no assurance that you will get the whole plant out this way.

You can also try pouring boiling hot water or spraying white vinegar on the target plants. This may take more time than using a synthetic herbicide, but you can feel a little better about using these products.

You can also try to use wood chips to cover a certain area where you do not want anything to grow. This will not stop all the weeds, but the few that make it through can be easily picked by hand.

Common Problems

Is sweet wormwood invasive?

more more
Generally species from Artemisia genus are not invasive, except very few such as Common Mugwort (A. vulgaris) and Absinth Wormwood (A. absinthium) are considered to be invasive in the US. They spread slowly by rhizomes and herbicides can be applied to eradicate them.

Why has my sweet wormwood started to flop over?

more more
If grown in shade, it tends to flop over. Properly pruning the plant and keeping it under the full sun will prevent this problem. If shading is not the case, flopping over can happen after flowering and be prevented by shearing the plant during midsummer.

Indoor plants require adequate lighting for optimal growth. When natural sunlight is insufficient, particularly in winter or in less sunny spaces, artificial lights offer a vital solution, promoting faster, healthier growth.
1. Choose the right type of artificial light: LED lights are a popular choice for indoor plant lighting because they can be customized to provide the specific wavelengths of light that your plants need.
Full sun plants need 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft.
2. Determine the appropriate distance: Place the light source 12-36 inches above the plant to mimic natural sunlight.
3. Determine the duration: Mimic the length of natural daylight hours for your plant species. most plants need 8-12 hours of light per day.
Important Symptoms
Insufficient light
Sweet wormwood, a plant that thrives in full sunlight, is commonly grown outdoors with ample sunlight. When cultivated indoors with inadequate light, it may exhibit subtle symptoms of light deficiency.
View more
(Symptom details and solutions)
Small leaves
New leaves may grow smaller in size compared to the previous ones once they have matured.
Leggy or sparse growth
The spaces between leaves or stems of your sweet wormwood may become longer, resulting in a thin and stretched-out appearance. This can make the plant look sparse and weak, and it may easily break or lean due to its own weight.
Faster leaf drop
When plants are exposed to low light conditions, they tend to shed older leaves early to conserve resources. Within a limited time, these resources can be utilized to grow new leaves until the plant's energy reserves are depleted.
Slower or no new growth
Sweet wormwood enters a survival mode when light conditions are poor, which leads to a halt in leaf production. As a result, the plant's growth becomes delayed or stops altogether.
Lighter-colored new leaves
Insufficient sunlight can cause leaves to develop irregular color patterns or appear pale. This indicates a lack of chlorophyll and essential nutrients.
Solutions
1. To ensure optimal growth, gradually move plants to a sunnier location each week, until they receive at least 6 hours of direct sunlight daily. Use a south-facing window and keep curtains open during the day for maximum sunlight exposure and nutrient accumulation.2. To provide additional light for your plant, consider using artificial light if it's large or not easily movable. Keep a desk or ceiling lamp on for at least 8 hours daily, or invest in professional plant grow lights for ample light.
Excessive light
Sweet wormwood thrives in full sun exposure and can tolerate intense sunlight. With their remarkable resilience, symptoms of sunburn may not be easily visible, as they rarely suffer from it.
View more
(Symptom details and solutions)
Chlorosis
Chlorosis is a condition where the plant's leaves lose their green color and turn yellow. This is due to the breakdown of chlorophyll from excessive sunlight, which negatively affects the plant's ability to photosynthesize.
Sunscald
Sunscald occurs when the plant's leaves or stems are damaged by intense sunlight exposure. It appears as pale, bleached, or necrotic areas on the plant tissue and can reduce the plant's overall health.
Leaf Curling
Leaf curling is a symptom where leaves curl or twist under extreme sunlight conditions. This is a defense mechanism used by the plant to reduce its surface area exposed to sunlight, minimizing water loss and damage.
Wilting
Wilting occurs when a plant loses turgor pressure and its leaves and stems begin to droop. Overexposure to sunlight can cause wilting by increasing the plant's water loss through transpiration, making it difficult for the plant to maintain adequate hydration.
Leaf Scorching
Leaf scorching is a symptom characterized by the appearance of brown, dry, and crispy edges or patches on leaves due to excessive sunlight. This can lead to a reduction in photosynthetic capacity and overall plant health.
Solutions
1. Move your plant to the optimal position where it can receive abundant sunlight but also have some shade. An east-facing window is an ideal choice as the morning sunlight is gentler. This way, your plant can enjoy ample sunlight while reducing the risk of sunburn.2. It is recommended to trim off any completely dehydrated or withered parts of the plant.

Essentials
Sweet wormwood is a plant with a fondness for warm environments. It typically thrives in temperatures of 68 to 95 °F (20 to 35 ℃). To keep it healthy, adjust its growing conditions according to the seasons, ensuring a warm environment especially during cooler months.
Regional wintering strategies
Sweet wormwood has strong cold resistance, so special frost protection measures are usually not necessary during winter. However, if the winter temperatures are expected to drop below {Limit_growth_temperature}, it is still important to provide cold protection. This can be achieved by covering the plant with materials such as soil or straw. Before the first freeze in autumn, it is recommended to water the plant abundantly, ensuring the soil remains moist and enters a frozen state. This helps prevent drought and water scarcity for the plant during winter and early spring.
Important Symptoms
Low Temperature
Sweet wormwood is cold-tolerant and thrives best when the temperature is above {Suitable_growth_temperature_min}. During winter, it should be kept above {Tolerable_growing_temperature_min}. When the temperature falls below {Limit_growth_temperature}, although there may not be any noticeable changes during winter, there may be a decrease in sprouting or even no sprouting during springtime.
Solutions
In spring, remove any parts that have failed to sprout.
High Temperature
During summer, Sweet wormwood should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the leaves of the plant may become lighter in color, prone to curling, susceptible to sunburn, and in severe cases, the entire plant may wilt and become dry.
Solutions
Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun, or use a shade cloth to create shade. Water the plant in the morning and evening to keep the soil moist.
