Common Pests & Diseases

























- Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree.
- Contact an arborist for best control practices regarding infected trees.
- To properly control longhorn beetles, all host plants in a given area must be treated.
- Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.

- Keeping trees healthy, uninjured, and unstressed will help prevent beetle infestation. Water trees appropriately, giving neither too much nor too little.
- Check with local tree companies about which tree species have fewer problems.
- Avoid moving firewood as this can introduce exotic longhorn beetles.
- Routine spraying of persistent, broad-spectrum insecticides will help prevent re-infestation of previously affected trees or infestation of unaffected trees.






- Both leaves and blossom on the tips of branches will go brown and wither.
- Gray powdery patches will appear on infected leaves and flowers, and this will be most apparent after rain.
- Any fruit that does appear will turn wrinkled and fail to develop.
- Branch tips begin to die, progressing back to larger branches, causing general deterioration of the tree or plant.


- Remove any fruit as soon as it shows any signs of infection. Do not compost.
- Use a fungicide prior to leaf bud and then as per manufacturers instructions throughout the season.

- Ensuring adequate spacing between plants or trees.
- Staking plants that are prone to tumbling to prevent moisture or humidity build up.
- Prune correctly so that there is adequate air movement and remove any dead or diseased branches that may carry spores.
- Practice good plant hygiene by removing fallen material and destroying it as soon as possible.





- 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.
- 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.

- 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.

- 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.






- Yellow, brown, or blackened leaves starting with the leaf margins
- Dying twig tips on trees and shrubs as leaves die and fall
- Often there is a bright yellow border line between the dead and living leaf tissue


- Mulching the root zone (preferably with wood chip mulch) helps retain moisture, reduce evaporation, and promotes a healthy, functional root environment that is critical for water movement to the leaves.
- Check the root collar for girdling or circling roots that strangle the trunk and limit water and nutrient movement.
- Protect trees from severe root damage of nearby construction and excavation.
- If fertilizer burn is to blame, irrigate the soil deeply to flush out excess fertilizer salts. However, keep in mind that fertilizer runoff is an environmental pollutant. Avoiding excess fertilization in the first place is the best approach.
- If soil testing has revealed a potassium deficiency, apply a potassium fertilizer and water well. Even if you have enough potassium in the soil, plants will not be able to take it up if the soil is consistently too dry.
- Severely affected twigs may be removed using a pair of sharp and sanitized pruning shears, as weakened branches are susceptible to secondary infections.
- If your plant has bacterial leaf scorch, there is no cure. Antibiotic injections applied by a professional can reduce symptoms for a season, however, the above cultural management methods are the best options to reduce symptoms and prolong life. An infected plant will likely die within ten years.

- Physiological leaf scorch is best avoided by making sure your plants have a healthy, functional root system and access to enough water. Water regularly, especially on the mornings of excessively hot, sunny days. Deep, infrequent irrigation is better than shallow, frequent irrigation.
- Have your soil tested and apply the proper nutrients. Be sure to not over-apply fertilizers.
- Make sure your plants’ roots have room to expand. Avoid compacted soil as well and avoid paving areas above the root zone. Do not till or disturb the soil where plant roots are growing.
- Plant new trees and shrubs in the fall, so that they have the maximum amount of time to become established before the environmental stresses of the next summer.
- Remove any dead or dying plant tissue that may harbor secondary infections.
















- Extreme heat and dry weather (when growing outdoors)
- Grow lights or indoor lighting that is too bright or intense for the type of plant
- Using fast-draining growing media such as sand


- Choose pots with adequately-sized drainage holes
- Avoid warm temperatures
- Use large pots with additional soil (these take longer to dry out)
- Avoid terracotta pots, which lose water quickly
