Exotica plants are beautiful and exotic, which is why they are a popular choice for gardeners. However, these plants are prone to borers, which can cause significant damage and even kill the plant. Borers are small insects that bore into the plant’s stem, causing it to weaken and eventually die. In this article, we will discuss how to get rid of borers on exotica plants.

What are Borers?

Borers are small insects that bore into the stem of plants, causing damage and sometimes death. These insects can be difficult to spot because they are often hidden inside the plant’s stem. Some common types of borers include:

  • Emerald Ash Borer
  • Peach Tree Borer
  • Lilac Borer
  • Dogwood Borer

Signs of Borer Infestation

The first sign of a borer infestation is usually wilting or yellowing leaves. As the infestation progresses, you may notice holes in the stem or sawdust-like material around the base of the plant. If left untreated, the plant may eventually die.

How to Get Rid of Borers

  1. Prune Affected Areas: The first step in getting rid of borers is to prune affected areas. Use a sharp and clean pair of pruning shears to remove any dead or dying branches. This will help reduce the number of borers in the area.

  2. Apply Insecticide: Insecticides can be effective in treating borer infestations. Look for an insecticide that is labeled for use on your specific type of plant and follow the instructions carefully.

  3. Use Beneficial Nematodes: Beneficial nematodes are microscopic worms that feed on insect larvae, including borers. You can purchase nematodes at your local garden center and apply them to the soil around your plants.

  4. Keep Plants Healthy: Healthy plants are less likely to be affected by borers. Make sure your plants are getting the right amount of water and nutrients, and avoid over-fertilizing.

  5. Use Sticky Traps: Sticky traps can help catch adult borers before they have a chance to lay eggs in your plants. You can purchase sticky traps at your local garden center or make your own using yellow or blue cardboard coated with sticky material.

  • Keep plants healthy by providing proper care and maintenance.
  • Avoid planting new plants near infected areas.
  • Remove any dead or dying branches as soon as possible.
  • Use insecticides and beneficial nematodes as a preventive measure.
