How to Get Rid of Borers on Elderberry Plant

Elderberry plants are a staple in many gardens and backyards. They are known for their beautiful flowers and flavorful fruit, which can be used for making jams, jellies, and even wine. However, elderberry plants can also fall prey to borers, which can damage the plant and reduce its yield. In this article, we will explore how to get rid of borers on elderberry plants and keep your plants healthy and thriving.

Understanding Borers

Borers are insects that lay their eggs inside the bark of trees and shrubs. When the eggs hatch, the larvae burrow into the wood and feed on the plant tissue. Elderberry borers are typically clearwing moths that lay their eggs on the bark of the plant. The larvae then bore into the wood, causing damage and weakening the plant.

Signs of Borer Infestation

The first sign of borer infestation on an elderberry plant is usually wilting or yellowing leaves. The plant may also have dead or dying branches. If you inspect the plant closely, you may be able to see holes in the bark or sawdust-like frass around the base of the plant.

Prevention

Prevention is key when it comes to borer infestations. Here are some tips for preventing borers from attacking your elderberry plants:

• Plant healthy plants: Start with healthy elderberry plants from a reputable nursery.
• Prune regularly: Regular pruning helps to keep the plant healthy and promotes good airflow around the branches.
• Mulch: Mulching around the base of the plant helps to retain moisture and protect against extreme temperatures.
• Water properly: Make sure your elderberry plant is getting enough water, but not too much. Overwatering can weaken the plant and make it more susceptible to borers.

Treatment

If you suspect that your elderberry plant has a borer infestation, there are several treatment options to consider:

• Insecticides: Insecticides can be effective in controlling borers, but they should be used as a last resort. Look for insecticides that are labeled for use on elderberry plants and follow the instructions carefully.
• Removing infested branches: If the infestation is localized, you may be able to remove the infested branches and prevent the borers from spreading.
• Beneficial nematodes: Beneficial nematodes are microscopic worms that can be introduced to the soil around the base of the plant. They attack the larvae of borers and other pests.
• Traps: Pheromone traps can be used to lure male clearwing moths away from your elderberry plants. This can help to reduce the number of eggs that are laid on the bark.

Conclusion

Borer infestations can be a serious problem for elderberry plants. However, with proper prevention and treatment, you can keep your plants healthy and productive. Regularly inspect your plants for signs of infestation and take action as soon as possible to prevent further damage.
