How to Get Rid of Borers on Corn Tree Plant

Updated: March 27, 2022

Corn tree plants are a beautiful addition to any garden or landscape. However, they are not immune to pests like borers. Borers are small insects that lay their eggs in the bark of trees, and their larvae feed on the tree’s inner bark, causing significant damage. If left unchecked, they can kill your corn tree plant. In this article, we will discuss how to get rid of borers on corn tree plants.

Identify the Signs of Borer Infestation

Before you can begin treating your corn tree plant for borers, you need to be able to identify the signs of an infestation. Some of the signs you should look for include:

  • Holes in the bark
  • Sawdust-like material around the base of the tree
  • Wilting or yellowing leaves
  • Lack of new growth
  • Dieback of branches

If you notice any of these signs, it is important to act quickly to prevent further damage.

Remove Infected Branches

The first step in getting rid of borers on your corn tree plant is to remove any branches that are infected. Use pruning shears to cut off the infected branch as close to the trunk as possible. Be sure to sanitize your pruning shears between cuts with rubbing alcohol or bleach to prevent spreading the infestation.

Use Pesticides

Another effective way to get rid of borers on corn tree plants is to use pesticides. There are several types of pesticides that are effective against borers, including systemic insecticides and contact insecticides.

Systemic insecticides are absorbed by the plant and provide long-lasting protection against borers. Contact insecticides, on the other hand, kill borers on contact but do not provide long-lasting protection. It is important to follow the instructions on the pesticide label carefully and wear protective gear when applying pesticides.

Implement Preventative Measures

Preventing borers from infesting your corn tree plant in the first place is the best way to protect it. Here are some preventative measures you can take:

  • Keep your corn tree plant healthy by providing it with adequate water and nutrients.
  • Avoid injuring the bark of your corn tree plant.
  • Remove any dead or dying branches promptly.
  • Apply a protective insecticide to your corn tree plant in early spring before the borers emerge.


Can borers be eradicated completely?

While it is possible to get rid of borers on your corn tree plant, it is challenging to eradicate them completely. The best approach is to implement preventative measures to keep them from infesting your tree in the first place.

Is it safe to use pesticides on my corn tree plant?

When used according to the instructions on the label, pesticides are generally safe for use on corn tree plants. However, it is essential to wear protective gear and follow all safety precautions when applying pesticides.

How can I tell if my corn tree plant is healthy?

A healthy corn tree plant should have vibrant green leaves and a sturdy trunk. It should also show signs of new growth each year. If you notice any wilting or yellowing leaves or lack of new growth, it may be a sign that your tree is not healthy.

In conclusion, borers can cause significant damage to your corn tree plant if left unchecked. Identifying the signs of an infestation, removing infected branches, using pesticides, and implementing preventative measures are all effective ways to get rid of borers on your corn tree plant. By following these steps, you can help protect your corn tree plant and keep it healthy for years to come.
