Care Guide for Canada goldenrod
Canada goldenrod is a relatively drought-tolerant plant and mature specimens don't require additional water except in drought conditions. If the soil becomes fully dry, then water as required. Young plants need more water; check the surrounding soil, and water often enough to keep it moist.
Canada goldenrod is an uncommon species that does not require any form of artificial fertilization. Adding fertilizer will, in fact, damage the plant and result in the plant's stem losing rigidity. Fertilization also results in the plant producing fewer flowers.
Trim the diseased, withered leaves once a month.

Fertilizing What is the best way to water my Canada goldenrod?
When watering the Canada goldenrod, you should aim to use filtered water that is at room temperature. Filtered water is better for this plant, as tap water can contain particles that are harmful to its health. The reason that the water should be at room temperature or slightly warmer is that the Canada goldenrod comes from a warm environment, and cold water can be somewhat of a shock to its system. Also, you should avoid overhead watering for this plant, as it can cause foliage complications. Instead, simply apply your filtered room temperature water to the soil until the soil is entirely soaked. Soaking the soil can be very beneficial for this plant as it moistens the roots and helps them continue to spread through the soil and collect the nutrients they need.

What should I do if I water my Canada goldenrod too much or too little?
Both overwatering and underwatering will be detrimental to the health of your Canada goldenrod, but overwatering is a far more common issue. When this species receives too much water, its stems and leaves may begin to wilt and turn from green to yellow. Overwatering over a prolonged period may also lead to diseases such as root rot, mold, and mildew, all of which can kill your plant. Underwatering is far less common for the Canada goldenrod, as this plant has decent drought tolerance. However, underwatering remains a possibility, and when it occurs, you can expect to find that the leaves of your Canada goldenrod have become brittle and brown.
It is crucial that you notice the signs of overwatering as soon as possible when caring for your Canada goldenrod. Some of the diseases that arise from overwatering, such as root rot, may not be correctable if you wait too long. If you see early signs of overwatering, you should reduce your watering schedule immediately. You may also want to assess the quality of soil in which your Canada goldenrod grows. If you find that the soil drains very poorly, you should replace it immediately with a loose, well-draining potting mix. On the other hand, if you find signs that your Canada goldenrod is receiving too little water, all you need to do is water more regularly until those signs have subsided.

How often should I water my Canada goldenrod?
If your plant is in a pot. The most precise way to decide whether your Canada goldenrod needs water is to plunge your finger into the soil. If you notice that the first two to three inches of soil have become dry, it is time to add some water.
If you grow your Canada goldenrod outdoors in the ground, you can use a similar method to test the soil. Again, when you find that the first few inches of soil have dried out, it is time to add water. During the spring and early fall, this method will often lead you to water this plant about once every week. When extremely hot weather arrives, you may need to increase your watering frequency to about twice or more per week. With that said, mature, well-established the Canada goldenrod can show an admirable ability to withstand drought.

How much water does my Canada goldenrod need?
When it comes time to water your Canada goldenrod, you should not be shy about how much water you give. With the first two to three inches of soil dry, this plant will appreciate a long and thorough watering. Supply enough water to soak the soil entirely. The amount of water you add should be enough to cause excess water to flow through the drainage holes at the bottom of your pot. If you don’t see excess water draining from the pot, you have likely underwatered your plant. But do not let the water accumulate inside the soil, which will be very dangerous to the plant as well. Alternatively, a lack of water draining through the pot could indicate poorly draining soils, which is detrimental to the health of this plant and should be avoided. If the plant is outside, 1 inch of rain per week will be sufficient.

How should I water my Canada goldenrod at different growth stages?
The water needs of the Canada goldenrod can change depending on growth stages as well. For example, when your Canada goldenrod is in the first few years of its life, or if you have just transplanted it to a new growing location, you will need to give more water than usual. During both of those stages, your Canada goldenrod will put a lot of energy towards sprouting new roots that will then support future growth. For those roots to perform their best, they need a bit more moisture than they would at a more mature phase. After a few seasons, your Canada goldenrod will need much less water. Another growth stage in which this plant may need more water is during the bloom period. Flower development can make use of a significant amount of moisture, which is why you might need to give your Canada goldenrod more water at this time.

How should I water my Canada goldenrod through the seasons?
The Canada goldenrod will have its highest water needs during the hottest months of the year. During the height of summer, you may need to give this plant water more than once per week, depending on how fast the soil dries out. The opposite is true during the winter. In winter, your plant will enter a dormant phase, in which it will need far less water than usual. In fact, you may not need to water this plant at all during the winter months. However, if you do water during winter, you should not do so more than about once per month. Watering too much at this time will make it more likely that your Canada goldenrod will contract a disease.

What's the difference between watering my Canada goldenrod indoors and outdoors?
It is most common to grow the Canada goldenrod indoors for any gardener that does not live in temperate and tropical regions. Those gardeners should consider the fact that soil in a container can dry out a bit faster than ground soil. Also, the presence of drying elements such as air conditioning units can cause your Canada goldenrod to need water on a more frequent basis as well. if you planted it outside. When that is the case, it’s likely you won’t need to water your Canada goldenrod very much at all. If you receive rainfall on a regular basis, that may be enough to keep your plant alive. Alternatively, those who grow this plant inside will need to water it more often, as allowing rainwater to soak the soil will not be an option.

Common Pests & Diseases
Common issues for Canada goldenrod based on 10 million real cases
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.
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.
Caterpillars
Caterpillars are fleshy moth or butterfly larvae that come in an array of colors, patterns, and even hairstyles. They chew on leaves and flower petals, creating large, irregular holes.
Solutions: Even though caterpillars are diverse, they all chew on plant parts and can cause significant damage if present in large numbers. For severe cases: Apply insecticide. For an organic solution, spray plants with a Bacillus thuringiensis (Bt), which specifically affects the larval stage of moths and butterflies. Be sure to coat plants, since caterpillars need to ingest Bt for it to be effective. This will not harm other insects. Spray a chili extract. Chili seeds can be cooked in water to make a spicy spray that caterpillars don't like. Spray this mixture on the plants, but be aware it will also be spicy to humans. Introduce beneficial insects. Release beneficial insects to the garden that eat caterpillars, such as parasitic wasps. For less severe cases: Hand pick. Using gloves, pick off caterpillars on plants and dispose of them in a bucket of soapy water. Dust plants with diatomaceous earth. This powder is harmless to humans but irritates caterpillars. Therefore, it will make it difficult for caterpillars to move and eat.
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.
Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Solutions: If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
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.

Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
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:
- Not enough water. A lack of water will lead to dry plant tissue.
- 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.
- 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.
- 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.
- Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
- 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:
- Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
- 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.
- 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.
- 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.
Prevention
Prevention involves providing your plant with the proper environment.
- 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.
- Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
- Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
- Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

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
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
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
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.
Prevention
To prevent infestations of leaf beetles, follow these practices.
- Regularly check for beetles. To prevent large pest infestations, be proactive about frequently checking plants for pests and removing them quickly.
- Clear debris. Clear weeds and debris to remove areas where these beetles may overwinter and hide.
- 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.
- Plant aromatic herbs like mint, garlic, or rosemary, as these can repel leaf beetles.

Caterpillars
Caterpillars are fleshy moth or butterfly larvae that come in an array of colors, patterns, and even hairstyles. They chew on leaves and flower petals, creating large, irregular holes.
Overview
Caterpillars can cause problems for home gardeners. If not managed, these insects can defoliate a plant in just a matter of days. However, home gardeners face a challenge because these caterpillars eventually turn into beautiful butterflies and moths, which are important for pollination and the general ecosystem.
There are thousands of different species of caterpillars and many will only target certain plants. If caterpillars are posing a problem, they can be removed by hand, or gardeners can use insect-proof netting to protect their valuable plants.
Symptom Analysis
Caterpillars are the larvae of butterflies and moths. During the warmer months, butterflies and moths that visit gardens will lay their eggs on the underside of leaves.
When the tiny eggs hatch, the young larvae emerge and start feeding on the leaves of the plant. Depending on how many larvae have hatched, they can easily defoliate the plant in a very short period of time. Caterpillars will shed their skin as they grow, around 4 or 5 times during this feeding cycle.
Symptoms of caterpillars eating plants appear as holes in the leaves. The edges of the leaves may be eaten away as well, and flowers can be affected as well.
Some are easy to see, but others need to be searched for. This is because their bodies are often camouflaged to look like part of the plant. Gardeners need to look carefully along the stems of the plant as well as under the leaves. Also, look for tiny white, yellow, or brown eggs that can be found in groups on the underside of leaves.
Once the caterpillar is fully grown, it transforms into a pupa or chrysalis. Then, after a period of time that varies according to the species, a butterfly or moth will emerge from the pupa and the cycle begins again.
Solutions
Even though caterpillars are diverse, they all chew on plant parts and can cause significant damage if present in large numbers.
For severe cases:
- Apply insecticide. For an organic solution, spray plants with a Bacillus thuringiensis (Bt), which specifically affects the larval stage of moths and butterflies. Be sure to coat plants, since caterpillars need to ingest Bt for it to be effective. This will not harm other insects.
- Spray a chili extract. Chili seeds can be cooked in water to make a spicy spray that caterpillars don't like. Spray this mixture on the plants, but be aware it will also be spicy to humans.
- Introduce beneficial insects. Release beneficial insects to the garden that eat caterpillars, such as parasitic wasps.
For less severe cases:
- Hand pick. Using gloves, pick off caterpillars on plants and dispose of them in a bucket of soapy water.
- Dust plants with diatomaceous earth. This powder is harmless to humans but irritates caterpillars. Therefore, it will make it difficult for caterpillars to move and eat.
Prevention
Prevention may require less effort than attempts to eradicate infestations that have already begun. Here are our top steps for prevention:
- Monitor plants. Check plants regularly for caterpillar eggs on leaves. If they do not belong to an endangered species, they should be squished.
- Use insect netting. Cover plants with insect netting to prevent butterflies and moths from laying eggs on plants.
- Apply diatomaceous earth. Apply DE to plants early in the season and reapply after rain.
- Encourage plant diversity. This will attract predatory insects including parasitic wasps.

Sap-sucking insects
Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
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
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.
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.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.
Solutions
If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
Prevention
Unfortunately, there is no way to prevent plants from dying of “old age.” To help prolong their life, and put off symptoms of aged yellow and dry for as long as possible, take care of them by giving them enough water, fertilizing them appropriately, and making sure they get enough sunlight.

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
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
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
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
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.

Weed Control
Weeds
The canada goldenrod is a weed native to North America. It prefers moist to dry soils such as open woods in USDA zones 5-10. It has been identified as an invasive weed in six countries: Belgium, Japan, South Africa, Russia, Finland, and South Korea. In Japan, the canada goldenrod competes with natural species of native grasses. The weed is used for ornamental purposes because of its flowers and the pollinators it attracts. It provides a food source for insects and shade cover for birds and small animals. The weed can be controlled through mechanical removal such as trimming or by exposing the weed to herbicides.
How to Control it
Best weeding time: before fruition Removal: You can remove this weed by gloved hand or by tool in early autumn or early spring each year. Due to it being perennial, you need to completely clean out its root system to prevent it from regrowth. Chemical control: If the weed is too much to pull out, herbicides will be helpful for its eradication. Mowing: Mow twice by the end of spring each year and repeatedly do so for two consecutive years, and the spread of the weed could be contained. For weed on larger-sized land, machine mowing is recommended.

Common issues for Canada goldenrod based on 10 million real cases
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.

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.

Caterpillars
Caterpillars are fleshy moth or butterfly larvae that come in an array of colors, patterns, and even hairstyles. They chew on leaves and flower petals, creating large, irregular holes.
Solutions: Even though caterpillars are diverse, they all chew on plant parts and can cause significant damage if present in large numbers. For severe cases: Apply insecticide. For an organic solution, spray plants with a Bacillus thuringiensis (Bt), which specifically affects the larval stage of moths and butterflies. Be sure to coat plants, since caterpillars need to ingest Bt for it to be effective. This will not harm other insects. Spray a chili extract. Chili seeds can be cooked in water to make a spicy spray that caterpillars don't like. Spray this mixture on the plants, but be aware it will also be spicy to humans. Introduce beneficial insects. Release beneficial insects to the garden that eat caterpillars, such as parasitic wasps. For less severe cases: Hand pick. Using gloves, pick off caterpillars on plants and dispose of them in a bucket of soapy water. Dust plants with diatomaceous earth. This powder is harmless to humans but irritates caterpillars. Therefore, it will make it difficult for caterpillars to move and eat.

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.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Solutions: If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.

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.

Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
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:
- Not enough water. A lack of water will lead to dry plant tissue.
- 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.
- 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.
- 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.
- Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
- 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:
- Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
- 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.
- 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.
- 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.
Prevention
Prevention involves providing your plant with the proper environment.
- 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.
- Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
- Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
- Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

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
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
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
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.
Prevention
To prevent infestations of leaf beetles, follow these practices.
- Regularly check for beetles. To prevent large pest infestations, be proactive about frequently checking plants for pests and removing them quickly.
- Clear debris. Clear weeds and debris to remove areas where these beetles may overwinter and hide.
- 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.
- Plant aromatic herbs like mint, garlic, or rosemary, as these can repel leaf beetles.

Caterpillars
Caterpillars are fleshy moth or butterfly larvae that come in an array of colors, patterns, and even hairstyles. They chew on leaves and flower petals, creating large, irregular holes.
Overview
Caterpillars can cause problems for home gardeners. If not managed, these insects can defoliate a plant in just a matter of days. However, home gardeners face a challenge because these caterpillars eventually turn into beautiful butterflies and moths, which are important for pollination and the general ecosystem.
There are thousands of different species of caterpillars and many will only target certain plants. If caterpillars are posing a problem, they can be removed by hand, or gardeners can use insect-proof netting to protect their valuable plants.
Symptom Analysis
Caterpillars are the larvae of butterflies and moths. During the warmer months, butterflies and moths that visit gardens will lay their eggs on the underside of leaves.
When the tiny eggs hatch, the young larvae emerge and start feeding on the leaves of the plant. Depending on how many larvae have hatched, they can easily defoliate the plant in a very short period of time. Caterpillars will shed their skin as they grow, around 4 or 5 times during this feeding cycle.
Symptoms of caterpillars eating plants appear as holes in the leaves. The edges of the leaves may be eaten away as well, and flowers can be affected as well.
Some are easy to see, but others need to be searched for. This is because their bodies are often camouflaged to look like part of the plant. Gardeners need to look carefully along the stems of the plant as well as under the leaves. Also, look for tiny white, yellow, or brown eggs that can be found in groups on the underside of leaves.
Once the caterpillar is fully grown, it transforms into a pupa or chrysalis. Then, after a period of time that varies according to the species, a butterfly or moth will emerge from the pupa and the cycle begins again.
Solutions
Even though caterpillars are diverse, they all chew on plant parts and can cause significant damage if present in large numbers.
For severe cases:
- Apply insecticide. For an organic solution, spray plants with a Bacillus thuringiensis (Bt), which specifically affects the larval stage of moths and butterflies. Be sure to coat plants, since caterpillars need to ingest Bt for it to be effective. This will not harm other insects.
- Spray a chili extract. Chili seeds can be cooked in water to make a spicy spray that caterpillars don't like. Spray this mixture on the plants, but be aware it will also be spicy to humans.
- Introduce beneficial insects. Release beneficial insects to the garden that eat caterpillars, such as parasitic wasps.
For less severe cases:
- Hand pick. Using gloves, pick off caterpillars on plants and dispose of them in a bucket of soapy water.
- Dust plants with diatomaceous earth. This powder is harmless to humans but irritates caterpillars. Therefore, it will make it difficult for caterpillars to move and eat.
Prevention
Prevention may require less effort than attempts to eradicate infestations that have already begun. Here are our top steps for prevention:
- Monitor plants. Check plants regularly for caterpillar eggs on leaves. If they do not belong to an endangered species, they should be squished.
- Use insect netting. Cover plants with insect netting to prevent butterflies and moths from laying eggs on plants.
- Apply diatomaceous earth. Apply DE to plants early in the season and reapply after rain.
- Encourage plant diversity. This will attract predatory insects including parasitic wasps.

Sap-sucking insects
Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
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
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.
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.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.
Solutions
If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
Prevention
Unfortunately, there is no way to prevent plants from dying of “old age.” To help prolong their life, and put off symptoms of aged yellow and dry for as long as possible, take care of them by giving them enough water, fertilizing them appropriately, and making sure they get enough sunlight.

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
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
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
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
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.

Weed Control
Weeds
The canada goldenrod is a weed native to North America. It prefers moist to dry soils such as open woods in USDA zones 5-10. It has been identified as an invasive weed in six countries: Belgium, Japan, South Africa, Russia, Finland, and South Korea. In Japan, the canada goldenrod competes with natural species of native grasses. The weed is used for ornamental purposes because of its flowers and the pollinators it attracts. It provides a food source for insects and shade cover for birds and small animals. The weed can be controlled through mechanical removal such as trimming or by exposing the weed to herbicides.
How to Control it
Best weeding time: before fruition Removal: You can remove this weed by gloved hand or by tool in early autumn or early spring each year. Due to it being perennial, you need to completely clean out its root system to prevent it from regrowth. Chemical control: If the weed is too much to pull out, herbicides will be helpful for its eradication. Mowing: Mow twice by the end of spring each year and repeatedly do so for two consecutive years, and the spread of the weed could be contained. For weed on larger-sized land, machine mowing is recommended.

Water
Canada Goldenrod Watering Instructions
Canada goldenrod, or Solidago altissima, originates from diverse regions across North America, spanning prairies, forests, and riverbanks. These varied environments, characterized by their heavy rainfall and considerable humidity, condition the plant's resilience to different watering conditions. Consequently, canada goldenrod tends to prefer moderate to abundant watering, mimicking the moisture levels it encounters in its indigenous habitats.
When Should I Water My Canada Goldenrod?
Introduction
Proper and timely watering plays a crucial role in maintaining the overall health and development of the canada goldenrod. It contributes to its optimal growth, vibrant flower production, and resistance against diseases. Therefore, understanding the appropriate signals indicating when the plant should be watered is essential.
Soil Moisture Level
One indicator for watering canada goldenrod is the moisture level of the soil. Insert your finger into the soil about 1-2 inches deep. If it feels dry at that depth, it's time to water the plant. However, if the soil feels moist or wet, it is not yet time to water.
Leaf Drooping
When canada goldenrod needs water, its leaves may begin to droop or wilt. This is a signal that the plant is experiencing water stress and requires watering. However, it's important to note that not all wilting leaves indicate the need for water, as other factors such as excessive sunlight or pests can cause wilting as well.
Leaf Color: Yellowing
If the leaves of canada goldenrod start turning yellow, it is a sign that the plant is under stress due to lack of water and needs to be watered. Yellowing leaves indicate that the plant is unable to access enough water to support its growth.
