How to Get Rid of Lerps on China Rose Plant

Updated: April 20, 2022

China rose plants are a beautiful addition to any garden. However, they are susceptible to a common pest known as lerps. Lerps are small, white, waxy, and scale-like insects that attach themselves to the leaves of the plant. They suck the sap from the leaves, causing them to turn yellow and eventually die. If left unchecked, lerps can cause severe damage to your china rose plant. In this article, we will discuss how to get rid of lerps on china rose plants.

Identify the Problem

The first step in getting rid of lerps is to identify the problem. Look for signs of yellowing leaves, stunted growth, and white waxy spots on the leaves. Lerps are usually found on the undersides of leaves and along the stems of the plant.

Natural Remedies

There are several natural remedies that you can use to get rid of lerps on your china rose plant.

Prune Infected Leaves

One of the easiest ways to get rid of lerps is to prune infected leaves. Use a pair of sharp pruning shears to cut off the infected leaves and dispose of them in a plastic bag. Be sure to seal the bag and throw it away in the trash.

Soap Water Solution

You can also use a soap water solution to get rid of lerps. Mix 1 tablespoon of dish soap with 1 quart of water and spray it on the infected leaves using a spray bottle. The soap will suffocate the lerps and cause them to die.

Neem Oil

Neem oil is another effective natural remedy for getting rid of lerps. Mix 2 tablespoons of neem oil with 1 gallon of water and spray it on the infected leaves using a spray bottle. Neem oil is a natural insecticide that will kill the lerps without harming your plant.

Chemical Remedies

If natural remedies do not work, you may need to use chemical remedies to get rid of lerps.

Insecticides

There are several insecticides available that are effective in getting rid of lerps. Look for insecticides that contain imidacloprid or acetamiprid. These chemicals are systemic and will be absorbed by the plant, killing the lerps from the inside out.

Horticultural Oil

Horticultural oil is another effective chemical remedy for getting rid of lerps. It works by suffocating the lerps and preventing them from breathing. Mix 2 tablespoons of horticultural oil with 1 gallon of water and spray it on the infected leaves using a spray bottle.
