What is the best way to water my Queen anne's lace?
To water Queen anne's lace, you can use a garden hose with a spray nozzle, a watering can, or just about any other common watering tool. Generally, Queen anne's lace 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 Queen anne's lace as they apply water evenly and directly to the soil. For one Queen anne's lace that grows in a container, you can use a similar watering approach while changing the tools you use. To water a container-grown Queen anne's lace, use a cup, watering can, or your tap to apply water directly to the soil.

What should I do if I water my Queen anne's lace too much or too little?
The remedy for underwatering Queen anne's lace 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 Queen anne's lace 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 Queen anne's lace 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 Queen anne's lace, make sure to add loose soils and to use a pot that drains efficiently.

How often should I water my Queen anne's lace?
Queen anne's lace 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 Queen anne's lace. With that said, you should also ensure that the soil in which your Queen anne's lace grows remains relatively moist but not wet, regardless of how often you must water to make that the case. Watering Queen anne's lace 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 Queen anne's lace a few times per week in most cases, versus just once per week for an in-ground plant.

How much water does my Queen anne's lace need?
There are a few different ways you can go about determining how much water to give to your Queen anne's lace. 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 Queen anne's lace. Typically, you should give your Queen anne's lace 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 Queen anne's lace 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 Queen anne's lace enough?
It can be somewhat difficult to avoid overwatering your Queen anne's lace. On the one hand, these plants have relatively deep roots that require you to moisten the soil weekly. On the other hand, Queen anne's lace are plants that are incredibly susceptible to root rot. Along with root rot, your Queen anne's lace may also experience browning as a result of overwatering. Underwatering is far less likely for your Queen anne's lace 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 Queen anne's lace through the seasons?
You can expect your Queen anne's lace’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 Queen anne's lace, at times increasing to about three times per week. This is especially true of Queen anne's lace 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 Queen anne's lace 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 Queen anne's lace at different growth stages?
Queen anne's lace 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 Queen anne's lace as a seed. While the seed germinates, you should plant to give more water than your Queen anne's lace will need later in life, watering often enough to maintain consistent soil moisture. After a few weeks, your Queen anne's lace 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 Queen anne's lace indoors and outdoors?
There are several reasons why most Queen anne's lace grow outdoors rather than indoors. The first is that these plants typically grow to tall. The second reason is that Queen anne's lace 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 Queen anne's lace 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.

Common issues for Queen anne's lace based on 10 million real cases
Flower withering
Flower withering Flower withering
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Solutions: If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible. For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface. In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well. If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.
Plant dried up
Plant dried up Plant dried up
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Root rot
Root rot Root rot
Root rot
Soft root rot can be caused by over-watering or pathogenic infection.
Solutions: These are the solutions for root rot: Stop applying water and allow the plant to dry out. In the case of potted plants, the gardener can remove plant from its container and lay it on a sheet of paper in a shady spot to speed the drying process. Cut away black mushy root material until healthy white material is reached. Sprinkle root ball with anti-fungal powder. Repot using sterilized potting mixture but don't water for first couple of days. Ensure that the new pot offers adequate drainage. Terracotta pots can absorb moisture into their walls. Adopt an appropriate watering regime. For most potted plants, refrain from watering until the first inch or two of the soil is dry to the touch. Even plants that prefer to be kept "evenly moist" should never be allowed to sit in soggy soil. Outdoor plants should not be receiving so much water that it pools at the surface of the soil.
Root deformity
Root deformity Root deformity
Root deformity
Root deformities can have a variety of causes
Solutions: There are a few key steps to take if root deformity is suspected: Prevent the spread of fungal diseases - if a fungal pathogen is to blame for the root deformity, there’s not much to do once it sets into the soil. Prevent it from spreading by applying a fungicide or adjusting the soil pH based on what is needed for the specific type of plant. Do not re-use this soil for future plantings. Harvest selectively - for root vegetables like carrots or parsnips, the tubers may still be usable. Cull some of the crop or cut away affected areas, but the rest should still be safe to eat.
Sap-sucking insects
Sap-sucking insects Sap-sucking insects
Sap-sucking insects
Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
Solutions: Sap-sucking insects can be hard to spot, as they are often small and attach to the undersides of plant leaves. If you see signs of an infestation, follow these steps to eradicate it. Hand-pick bugs and remove eggs: Inspect your plants for insects and drop any you find in a container of soapy water. Look carefully at the undersides of plant leaves and squish any egg clusters you find. Use Insecticide: Targeted spraying can take out sap-sucking insects. Small infestations can be controlled with insecticidal soap, though larger outbreaks might require a stronger spray. Introduce natural predators: Many insects, including ladybugs and praying mantises, love to feast on sap-suckers. You can purchase them at garden stores and release them near infected plants, or encourage wild ones by creating habitat space.
Brown spot
Brown spot Brown spot
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.

Flower withering
plant poor
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
  • Wilted, droopy flowers
  • Petals and leaves begin to wrinkle
  • Brown papery streaks or spots appear on the petals and leaf tips
  • Flowerhead shrink in size
  • Petal color fades
  • Yellowing leaves
  • Complete death of the flower
Disease Cause
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.

Plant dried up
plant poor
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Symptom Analysis
Symptom Analysis
Your plant has dried out and turned brown. It might be starting to wilt, with no noticeable green around the stems and leaves. Touch the leaves, and they may crinkle under your fingers.
Possible causes of a dried out plant include:
  1. Not enough water. A lack of water will lead to dry plant tissue.
  2. Too much water. Watering too much can lead to root rot which makes the plant struggle to take up water. Rotted, mushy roots are a sign of overeating.
  3. Entering dormancy. As perennial plants enter their resting period known as dormancy, their leaves dry out and may fall off. This happens during decreasing day length.
  4. Exposure to herbicides and other toxic substances. If a plant is hit with a large dose herbicide or other toxic chemical, the plant will turn brown.
  5. Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
  6. Improper sun exposure. Just like humans, plants can get sunburn by intense, direct light. Plants can also dry out if they don’t receive enough light.
To determine whether the plant is still alive and can be saved, you can:
  1. Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
  2. Gently scratch the stem with your fingernail for signs of green inside. If your plant is dead, the stem will be brittle and brown throughout.
  3. Cut the stems back a little bit a time for visible green growth. If none of the stems have visible green growth, the plant is dead.
Solutions
Solutions
The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method.
  1. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly.
  2. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems.

  4. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil.
  5. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Prevention
Prevention
Prevention involves providing your plant with the proper environment.
  1. Provide the proper amount of water. The amount of water depends on a plant’s size, species, and environment. A general rule is to allow soil to dry out between waterings.
  2. Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
  3. Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
  4. Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

Root rot
plant poor
Root rot
Soft root rot can be caused by over-watering or pathogenic infection.
Overview
Overview
Root rot is a common and devastating problem that can infect trees, shrubs and other plants, often with fatal results. It is caused by excessive moisture in the soil, which activates a fungus that can lie dormant in soil and only emerge when conditions are ideal (soggy and wet). Because primary symptoms are hidden beneath the soil, the gardener may not become aware of the problem until upper sections of the plant start to show signs of distress.
Symptom Analysis
Symptom Analysis
Early symptoms may occur below ground and not be obvious until they advance into more visible plant material. Above ground the gardener may be alerted by:
  1. Wilting and yellowing of the leaves.
  2. Softening and discoloration of the stems.
At this stage it is worth making a closer examination of what is going on below the soil.
  1. Soil will feel noticeably damp and boggy.
  2. There will often be a swampy smell emanating from the soil.
  3. Examination of the roots will reveal black or dark brown mushy material.
Disease Cause
Disease Cause
Root rot is caused by plant pathogens in the soil which are activated by overly-wet conditions. They invade the root material, which begins to die and rot. With roots no longer functioning effectively, there is a shortage of oxygen and nutrients being carried to the upper sections of the plant. These will show the signs of distress that may be what first alerts the gardener to this issue.

Root deformity
plant poor
Root deformity
Root deformities can have a variety of causes
Overview
Overview
Although root deformity is a problem that can occur with just about any type of plant, it tends to be more noticeable in root crops such as carrots, parsnips, or potatoes. In any plant, it is important to address root deformity in its early stages so that they are able to grow to their fullest potential.
Symptom Analysis
Symptom Analysis
There are countless symptoms of root deformity and associated root problems in plants. In fact, these symptoms often co-occur with dozens of others, making it hard to tell which disease, pest, or environmental condition is responsible for a given plant’s suffering and failure to thrive.
Some of the most common symptoms you will see in plants with root deformity problems are:
  • Roots that are misshapen, rotten, or stunted
  • Roots that become brown and mushy as areas begin to die back
  • Stunted growth
  • Wilted or yellowing leaves
  • Premature leaf drop
  • Delayed blooming
Root deformity is not a disease that occurs on its own but is instead a symptom of many other common plant problems. Because of that, it is exceedingly important to examine all the issues to figure out what is going wrong.
Disease Cause
Disease Cause
There are several reasons why plants may develop malformed roots.
One of the most common is related to the environment. Environmental conditions related to moisture, soil structure, and nutrient load can commonly cause issues with root formation.
Not all soils are conducive to creating healthy roots. Roots need room to grow, spread, and breathe. When plants are grown in soil that is rocky or composed of heavy clay, it does not give them the opportunity to do so. Roots that do most of the “storage work” for plants, such as those of beets, kohlrabi, potatoes, carrots, turnips, and so on, are most likely to suffer from this cause.
There are various plant diseases that can cause plant roots to become malformed. These are generally plant- and species-specific but can include diseases such as root rot. Clubroot is another disease that typically affects plants in the mustard family, such as cabbage, broccoli, and Brussels sprouts.
There are even pests, such as root-knot nematodes, that can cause root damage, malformation, and death in a long list of plant species.

Sap-sucking insects
Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
Symptom Analysis
Symptom Analysis
Your plant has developed tiny yellowish spots scattered across the leaves that look like mold or mildew. If these marks won't wipe off, they are likely caused by sap-sucking insects like aphids, squash bugs, scale bugs, leafhoppers, whiteflies, mites, mealybugs, and more.
Each of these pests uses mouthparts to pierce leaf tissues and suck the sap. uses mouthparts to pierce leaf tissues and suck the sap. Signs of damage are difficult to spot at first, but a large infestation can quickly compromise the whole plant. You're most likely to see sap-sucking insects during the hottest months because plants make easier targets when already weakened from heat or drought.
Though sap-sucking insects are unlikely to kill your plant on their own, they can severely weaken it and make it more susceptible to disease. They may also spread viruses from one plant to another as they feed.
Solutions
Solutions
Sap-sucking insects can be hard to spot, as they are often small and attach to the undersides of plant leaves. If you see signs of an infestation, follow these steps to eradicate it.

Prevention
Prevention
Healthy plants are less likely to suffer from sap-sucker attacks. Keep them fortified with fertilizer and the right amounts of water and sunlight. Plants that receive excess nitrogen are also more susceptible to attack, so don’t overfertilize. You should also remove weeds and tall grasses surrounding your outdoor plants so as not to create habitat space for the pests.

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
  • Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
  • Placement is often random and scattered as diseases are spread through raindrops.
  • May appear on lower leaves and the interior of the plant where humidity is higher.
  • Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
  • Leaf margins may turn yellow.
  • Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
  • Blotches grow in size until the entire leaf is brown.
  • The leaf falls off the plant.
Severe Symptoms
  • Partial or complete premature defoliation
  • Reduced growth
  • Increased susceptibility to pests and other diseases
Disease Cause
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.

Common issues for Queen anne's lace based on 10 million real cases
Flower withering
Flower withering Flower withering Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Solutions: If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible. For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface. In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well. If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.

Plant dried up
Plant dried up Plant dried up Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.

Root rot
Root rot Root rot Root rot
Soft root rot can be caused by over-watering or pathogenic infection.
Solutions: These are the solutions for root rot: Stop applying water and allow the plant to dry out. In the case of potted plants, the gardener can remove plant from its container and lay it on a sheet of paper in a shady spot to speed the drying process. Cut away black mushy root material until healthy white material is reached. Sprinkle root ball with anti-fungal powder. Repot using sterilized potting mixture but don't water for first couple of days. Ensure that the new pot offers adequate drainage. Terracotta pots can absorb moisture into their walls. Adopt an appropriate watering regime. For most potted plants, refrain from watering until the first inch or two of the soil is dry to the touch. Even plants that prefer to be kept "evenly moist" should never be allowed to sit in soggy soil. Outdoor plants should not be receiving so much water that it pools at the surface of the soil.

Root deformity
Root deformity Root deformity Root deformity
Root deformities can have a variety of causes
Solutions: There are a few key steps to take if root deformity is suspected: Prevent the spread of fungal diseases - if a fungal pathogen is to blame for the root deformity, there’s not much to do once it sets into the soil. Prevent it from spreading by applying a fungicide or adjusting the soil pH based on what is needed for the specific type of plant. Do not re-use this soil for future plantings. Harvest selectively - for root vegetables like carrots or parsnips, the tubers may still be usable. Cull some of the crop or cut away affected areas, but the rest should still be safe to eat.

Sap-sucking insects
Sap-sucking insects Sap-sucking insects Sap-sucking insects
Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
Solutions: Sap-sucking insects can be hard to spot, as they are often small and attach to the undersides of plant leaves. If you see signs of an infestation, follow these steps to eradicate it. Hand-pick bugs and remove eggs: Inspect your plants for insects and drop any you find in a container of soapy water. Look carefully at the undersides of plant leaves and squish any egg clusters you find. Use Insecticide: Targeted spraying can take out sap-sucking insects. Small infestations can be controlled with insecticidal soap, though larger outbreaks might require a stronger spray. Introduce natural predators: Many insects, including ladybugs and praying mantises, love to feast on sap-suckers. You can purchase them at garden stores and release them near infected plants, or encourage wild ones by creating habitat space.

Brown spot
Brown spot Brown spot Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.

Flower withering
plant poor
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
  • Wilted, droopy flowers
  • Petals and leaves begin to wrinkle
  • Brown papery streaks or spots appear on the petals and leaf tips
  • Flowerhead shrink in size
  • Petal color fades
  • Yellowing leaves
  • Complete death of the flower
Disease Cause
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.
Solutions
Solutions
If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface.
In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well.
If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.
Prevention
Prevention
This is definitely one of those instances where prevention is more effective than cure. Here are some preventative measures for avoiding premature flower withering.
  • Water plants according to their needs -- either keep the soil slightly moist or allow the top inch or two to dry out before watering again.
  • Fertilize lightly on a consistent basis, depending upon the plant’s growth. Quick-growing plants and those that flower or develop fruit will need more frequent fertilizing than slow-growing plants.
  • Purchase plants that are certified disease- or pathogen-free.
  • Look for disease-resistant cultivars.
  • Isolate plants showing disease symptoms to prevent the spread to neighboring plants.
  • Practice good plant hygiene by removing any fallen plant material as soon as possible.

Plant dried up
plant poor
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Symptom Analysis
Symptom Analysis
Your plant has dried out and turned brown. It might be starting to wilt, with no noticeable green around the stems and leaves. Touch the leaves, and they may crinkle under your fingers.
Possible causes of a dried out plant include:
  1. Not enough water. A lack of water will lead to dry plant tissue.
  2. Too much water. Watering too much can lead to root rot which makes the plant struggle to take up water. Rotted, mushy roots are a sign of overeating.
  3. Entering dormancy. As perennial plants enter their resting period known as dormancy, their leaves dry out and may fall off. This happens during decreasing day length.
  4. Exposure to herbicides and other toxic substances. If a plant is hit with a large dose herbicide or other toxic chemical, the plant will turn brown.
  5. Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
  6. Improper sun exposure. Just like humans, plants can get sunburn by intense, direct light. Plants can also dry out if they don’t receive enough light.
To determine whether the plant is still alive and can be saved, you can:
  1. Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
  2. Gently scratch the stem with your fingernail for signs of green inside. If your plant is dead, the stem will be brittle and brown throughout.
  3. Cut the stems back a little bit a time for visible green growth. If none of the stems have visible green growth, the plant is dead.
Solutions

The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method.
  1. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly.
  2. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems.
  3. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species.
  4. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil.
  5. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Prevention
Prevention
Prevention involves providing your plant with the proper environment.
  1. Provide the proper amount of water. The amount of water depends on a plant’s size, species, and environment. A general rule is to allow soil to dry out between waterings.
  2. Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
  3. Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
  4. Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

Root rot
plant poor
Root rot
Soft root rot can be caused by over-watering or pathogenic infection.
Overview
Overview
Root rot is a common and devastating problem that can infect trees, shrubs and other plants, often with fatal results. It is caused by excessive moisture in the soil, which activates a fungus that can lie dormant in soil and only emerge when conditions are ideal (soggy and wet). Because primary symptoms are hidden beneath the soil, the gardener may not become aware of the problem until upper sections of the plant start to show signs of distress.
Symptom Analysis
Symptom Analysis
Early symptoms may occur below ground and not be obvious until they advance into more visible plant material. Above ground the gardener may be alerted by:
  1. Wilting and yellowing of the leaves.
  2. Softening and discoloration of the stems.
At this stage it is worth making a closer examination of what is going on below the soil.
  1. Soil will feel noticeably damp and boggy.
  2. There will often be a swampy smell emanating from the soil.
  3. Examination of the roots will reveal black or dark brown mushy material.
Disease Cause
Disease Cause
Root rot is caused by plant pathogens in the soil which are activated by overly-wet conditions. They invade the root material, which begins to die and rot. With roots no longer functioning effectively, there is a shortage of oxygen and nutrients being carried to the upper sections of the plant. These will show the signs of distress that may be what first alerts the gardener to this issue.
Solutions
Solutions
These are the solutions for root rot:
  1. Stop applying water and allow the plant to dry out.
  2. In the case of potted plants, the gardener can remove plant from its container and lay it on a sheet of paper in a shady spot to speed the drying process.
  3. Cut away black mushy root material until healthy white material is reached.
  4. Sprinkle root ball with anti-fungal powder.
  5. Repot using sterilized potting mixture but don't water for first couple of days. Ensure that the new pot offers adequate drainage. Terracotta pots can absorb moisture into their walls.
  6. Adopt an appropriate watering regime. For most potted plants, refrain from watering until the first inch or two of the soil is dry to the touch. Even plants that prefer to be kept "evenly moist" should never be allowed to sit in soggy soil. Outdoor plants should not be receiving so much water that it pools at the surface of the soil.
Prevention
Prevention
With indoor plants these are the best preventative measures:
  1. Ensure that the container offers adequate drainage.
  2. Don't allow the plant to stand in a saucer filled with water.
  3. Adopt an appropriate watering regime which allows the plant to dry out between each watering, according to the preference of each species.
  4. Only use sterilized potting mixtures when planting up or re-potting.
With outdoor plants:
  1. Choose planting positions that offer effective drainage.
  2. Don't over-water.
  3. Rotate plants so that pathogens don't build up.

Root deformity
Root deformities can have a variety of causes
Overview
Overview
Although root deformity is a problem that can occur with just about any type of plant, it tends to be more noticeable in root crops such as carrots, parsnips, or potatoes. In any plant, it is important to address root deformity in its early stages so that they are able to grow to their fullest potential.
Symptom Analysis
Symptom Analysis
There are countless symptoms of root deformity and associated root problems in plants. In fact, these symptoms often co-occur with dozens of others, making it hard to tell which disease, pest, or environmental condition is responsible for a given plant’s suffering and failure to thrive.
Some of the most common symptoms you will see in plants with root deformity problems are:
  • Roots that are misshapen, rotten, or stunted
  • Roots that become brown and mushy as areas begin to die back
  • Stunted growth
  • Wilted or yellowing leaves
  • Premature leaf drop
  • Delayed blooming
Root deformity is not a disease that occurs on its own but is instead a symptom of many other common plant problems. Because of that, it is exceedingly important to examine all the issues to figure out what is going wrong.
Disease Cause
Disease Cause
There are several reasons why plants may develop malformed roots.
One of the most common is related to the environment. Environmental conditions related to moisture, soil structure, and nutrient load can commonly cause issues with root formation.
Not all soils are conducive to creating healthy roots. Roots need room to grow, spread, and breathe. When plants are grown in soil that is rocky or composed of heavy clay, it does not give them the opportunity to do so. Roots that do most of the “storage work” for plants, such as those of beets, kohlrabi, potatoes, carrots, turnips, and so on, are most likely to suffer from this cause.
There are various plant diseases that can cause plant roots to become malformed. These are generally plant- and species-specific but can include diseases such as root rot. Clubroot is another disease that typically affects plants in the mustard family, such as cabbage, broccoli, and Brussels sprouts.
There are even pests, such as root-knot nematodes, that can cause root damage, malformation, and death in a long list of plant species.
Solutions
Solutions
There are a few key steps to take if root deformity is suspected:
  • Prevent the spread of fungal diseases - if a fungal pathogen is to blame for the root deformity, there’s not much to do once it sets into the soil. Prevent it from spreading by applying a fungicide or adjusting the soil pH based on what is needed for the specific type of plant. Do not re-use this soil for future plantings.
  • Harvest selectively - for root vegetables like carrots or parsnips, the tubers may still be usable. Cull some of the crop or cut away affected areas, but the rest should still be safe to eat.
Prevention
Prevention
There are several steps for preventing root deformity from impacting your plants;
  • Address spacing issues - one of the most common reasons for root deformity is plants that are growing too close together. Space plants according to the recommendations listed on the seed packet or in the planting guidelines.
  • Thin plants - some plants benefit from thinning after they have germinated. Consult the planting guidelines for each species, but know that removing all but the healthiest seedlings can provide them with the space they need to grow.
  • Improve soil quality - rocky and compacted soils can cause root deformity. Aerate the soil prior to planting and remove as many rocky or clay-dominated areas as possible.

Sap-sucking insects
plant poor
Sap-sucking insects
Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
Symptom Analysis
Symptom Analysis
Your plant has developed tiny yellowish spots scattered across the leaves that look like mold or mildew. If these marks won't wipe off, they are likely caused by sap-sucking insects like aphids, squash bugs, scale bugs, leafhoppers, whiteflies, mites, mealybugs, and more.
Each of these pests uses mouthparts to pierce leaf tissues and suck the sap. uses mouthparts to pierce leaf tissues and suck the sap. Signs of damage are difficult to spot at first, but a large infestation can quickly compromise the whole plant. You're most likely to see sap-sucking insects during the hottest months because plants make easier targets when already weakened from heat or drought.
Though sap-sucking insects are unlikely to kill your plant on their own, they can severely weaken it and make it more susceptible to disease. They may also spread viruses from one plant to another as they feed.
Solutions

Prevention
Prevention
Healthy plants are less likely to suffer from sap-sucker attacks. Keep them fortified with fertilizer and the right amounts of water and sunlight. Plants that receive excess nitrogen are also more susceptible to attack, so don’t overfertilize. You should also remove weeds and tall grasses surrounding your outdoor plants so as not to create habitat space for the pests.

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
  • Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
  • Placement is often random and scattered as diseases are spread through raindrops.
  • May appear on lower leaves and the interior of the plant where humidity is higher.
  • Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
  • Leaf margins may turn yellow.
  • Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
  • Blotches grow in size until the entire leaf is brown.
  • The leaf falls off the plant.
Severe Symptoms
  • Partial or complete premature defoliation
  • Reduced growth
  • Increased susceptibility to pests and other diseases
Disease Cause
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.
Solutions
Solutions
In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary.
Organic options won’t kill the fungus, but will prevent it from spreading.
  1. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear.
  2. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread.
  3. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Prevention
Prevention
Like many other diseases, it is easier to prevent brown spot than cure it, and this is done through cultural practices.
  • Clear fall leaves from the ground before winter to minimize places where fungi and bacteria can overwinter.
  • Maintain good air movement between plants through proper plant spacing.
  • Increase air circulation through the center of plants through pruning.
  • Thoroughly clean all pruning tools after working with diseased plants.
  • Never dispose of disease plant material in a compost pile.
  • Avoid overhead watering to keep moisture off of the foliage.
  • Keep plants healthy by providing adequate sunlight, water, and fertilizer.
