Common Pests & Diseases





















- 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.






- 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.






- Brown lesions form on the fruit and occasionally the blossoms. These lesions become soft, mushy, and develop a fuzzy gray or brown coating.
- The infection will very quickly spread to any fruit in contact with those that are infected.
- Fruit may drop or remain on the plant and mummify over time.
- Infection may spread to leaves and new branches, eventually leading to demise of the entire plant .


- Prune away infected fruits or flowers. As soon as lesions or fuzz are seen, cut away the infected parts and dispose of them. Do not compost.
- Apply fungicide to plants with mild infections (those with severe infections may need to be destroyed).
- Increase airflow. Since spores are mainly wind born, increasing the airflow around your plants will make them less susceptible to infection. Maintain maximum space between plants and open branch structures during the pruning season.

- Rake up rotting debris when the growing season is over. Fungi can overwinter on rotting debris and reinfect plants the following season. Clear the ground beneath fruit trees and remove hanging mummified fruit.
- Prune off any infected branches.
- Burn all infected debris.
- Preemptively apply fungicide to susceptible plants, especially in the spring. This can help prevent infections from progressing to a stage where fruits are affected.
- Don't overcrowd when planting. Overcrowding will reduce air circulation, leaving plants wetter for longer and increasing the chance of infection.
- Use drip irrigation instead of overhead irrigation. This will help keep plant surfaces free of moisture, while still ensuring roots are getting enough water. Hose-watering should be performed early in the day, with the spray directed at the base of plants.
- Don't over-fertilize early in the spring. Added nutrients will increase leaf size. As leaves can hold moisture and provide a surface for spores to adhere to, this can increase the chance that mold grows on the plant. Fertilizing later in the season, when fruits are ripening, means additional nutrients will be directed towards those fruits, rather than leaves.
- Insect prevention measures will reduce wounds on plants and decrease access points for fungal spores.






- Slightly raised, white spots on the undersides of the leaves and stems.
- These spots then turn a reddish-orange color, which indicates the presence of fungal spores.
- Reddish-orange spots appear on the upper sides of the leaves as well.
- Eventually, the rust spots form pustules or raised lumps that can turn yellow-green and finally black.
- Highly infected leaves will become yellow and drop off the plant.


- Remove infected leaves: eliminate fungal spores by picking off infected leaves and throwing them in the garbage. Do not compost them since this can spread the fungus to other plants.
- Use fungicide: A copper spray, sulfur powder, or broad-spectrum fungicide can help control a rust outbreak. Be sure to read all usage instructions carefully before applying.
- Water smarter: Keep plant leaves dry by watering in the morning so that the midday sun will dry them. It's also smart to use a soaker hose or drip irrigation to water only at the soil level.

1. Choose the right type of artificial light: LED lights are a popular choice for indoor plant lighting because they can be customized to provide the specific wavelengths of light that your plants need.
Full sun plants need 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft.
2. Determine the appropriate distance: Place the light source 12-36 inches above the plant to mimic natural sunlight.
3. Determine the duration: Mimic the length of natural daylight hours for your plant species. most plants need 8-12 hours of light per day.
