How to Get Rid of Lerps on Corn Tree Plant

Corn tree plants are popular indoor plants that are easy to care for and add a touch of greenery to any room. However, one common problem that corn tree plant owners face is the presence of lerps. Lerps are small, white, waxy bumps that appear on the leaves of the plant. They are actually the protective covering of small insects called psyllids, which feed on the sap of the plant. If left untreated, lerps can cause damage to the plant and even kill it. Here are some methods to get rid of lerps on corn tree plants.

1. Prune Infected Leaves

One of the simplest methods to get rid of lerps is by pruning the infected leaves. Use a pair of clean and sharp pruning shears to cut off the affected leaves. Make sure to dispose of them properly to prevent the spread of any remaining psyllids.

2. Use a Hose

Another effective method is using a hose to spray down the plant. The high-pressure water will help remove the lerps and any remaining psyllids from the leaves. Make sure to aim at the underside of the leaves where the insects like to hide.

3. Neem Oil Spray

Neem oil is an organic insecticide that can be used to get rid of lerps. Mix 1 tablespoon of neem oil with 1 quart of water and add a few drops of dish soap. Spray this solution onto the infected leaves, making sure to cover both sides of each leaf. Repeat this every week until all signs of lerps have disappeared.

4. Insecticidal Soap

Insecticidal soap is another effective option for getting rid of lerps on corn tree plants. Mix 1 tablespoon of insecticidal soap with 1 quart of water and spray it directly onto the infected leaves. The soap will suffocate the psyllids, causing them to die off. Repeat this every week until all signs of lerps have disappeared.

5. Ladybugs

Ladybugs are natural predators of psyllids and can be used as a biological control method for getting rid of lerps. You can purchase ladybugs online or from your local garden center. Release the ladybugs onto the infected plant and let them do their work.

6. Maintain Plant Health

Prevention is always better than cure, so it’s important to maintain the health of your corn tree plant to prevent lerps from appearing in the first place. Make sure to fertilize the plant regularly and keep it well-watered. Avoid over-fertilizing, as this can attract psyllids.
