How to Get Rid of Scales on Corn Tree Plant

If you’re an avid gardener or just love plants, you may have come across the corn tree plant. This plant is known for its ability to thrive in low-light environments and its ability to grow tall, making it a popular choice for indoor gardening. However, like any other plant, the corn tree plant can be susceptible to pests and diseases. One of the most common pests that affect this plant is scales.

What are Scales?

Scales are tiny insects that attach themselves to the stem and leaves of plants. They feed on the sap of the plant and can cause significant damage if not treated promptly. Scales are usually brown or black in color and have a hard shell that protects them from predators and pesticides.

Identifying Scales on Corn Tree Plant

To identify scales on your corn tree plant, look for brown or black spots on the leaves and stems. These spots may be slightly raised and have a shiny appearance. You may also notice a sticky substance on the leaves or a yellowing of the leaves.

Getting Rid of Scales on Corn Tree Plant

Getting rid of scales on your corn tree plant requires persistence and patience. Here are some steps you can take to eliminate these pesky insects:

Step 1: Manual Removal

The first step is to manually remove as many scales as possible from your plant. Use a soft-bristled brush or cotton swab dipped in rubbing alcohol to gently scrub the scales off the stem and leaves of your corn tree plant. Be sure to dispose of any scales you remove, so they do not reattach themselves to the plant.

Step 2: Insecticidal Soap

Insecticidal soap is an effective treatment for scales on your corn tree plant. It works by suffocating the insects and disrupting their life cycle. Apply insecticidal soap to your plant according to the manufacturer’s instructions. Be sure to cover all parts of the plant thoroughly.

Step 3: Neem Oil

Neem oil is another effective treatment for scales on your corn tree plant. It works by disrupting the insect’s hormonal balance, preventing them from feeding and reproducing. Mix neem oil with water and apply it to your plant using a spray bottle. Be sure to cover all parts of the plant thoroughly.

Step 4: Systemic Insecticides

If you have a severe infestation of scales on your corn tree plant, you may need to use a systemic insecticide. This type of treatment is absorbed by the plant and travels through its vascular system, making it an effective long-term solution. Be sure to follow the manufacturer’s instructions carefully when using systemic insecticides.
