Burning bush (Euonymus alatus) is a popular landscaping plant known for its bright red fall foliage. However, like any other plant, burning bushes can be susceptible to pests that can damage or even kill the plant. This article will discuss the most common burning bush plant pests and provide tips for preventing and controlling them.
Common Burning Bush Plant Pests
Spider Mites
Spider mites are tiny pests that can be found on the undersides of burning bush leaves. They feed on the sap of the plant, causing it to appear yellow and dry. Spider mites thrive in hot, dry conditions, so they are most active during the summer months.
Scale Insects
Scale insects are small, oval-shaped pests that attach themselves to burning bush stems and leaves. They feed on the sap of the plant, causing it to weaken and become stunted. Scale insects secrete a sticky substance called honeydew that attracts ants and can cause black mold to grow on the plant.
Japanese Beetles
Japanese beetles are metallic-green pests that feed on burning bush leaves. They skeletonize the leaves by eating the tissue between the veins, leaving only a lacy skeleton behind. Japanese beetles are most active during the summer months.
Bagworms
Bagworms are caterpillars that construct bags made of silk and bits of foliage. They attach these bags to burning bush branches and feed on the foliage inside. Bagworms can defoliate an entire burning bush if left unchecked.
Prevention and Control Methods
Prevention
Prevention is the best method for controlling burning bush pests. Here are some tips for preventing pest infestations:
- Plant healthy bushes: Start with healthy burning bushes that have been grown in disease-free soil.
- Prune regularly: Prune your burning bush regularly to remove dead or damaged branches and foliage.
- Water properly: Water your burning bush deeply once a week instead of shallowly every day.
- Fertilize appropriately: Use a slow-release, balanced fertilizer in early spring.
- Monitor regularly: Inspect your burning bush regularly for signs of pest infestations.
Control
If you do find pest infestations on your burning bush, here are some methods for controlling them:
- Hand-pick: For small infestations, hand-picking pests off your burning bush can be effective.
- Spray: Use an insecticidal soap or neem oil spray to control spider mites and scale insects.
- Apply insecticide: Apply an insecticide containing carbaryl, permethrin, or lambda-cyhalothrin to control Japanese beetles.
- Remove bags: Hand-remove bagworm bags from your burning bush and destroy them.
