Gaura is a beautiful plant that can add a touch of elegance to any garden. However, it is not immune to pests, and one of the most common problems it faces is the presence of lerps. Lerps are small, white, waxy structures that appear on the leaves and stems of the Gaura plant. These structures are created by an insect called the lerp psyllid, which feeds on the sap of the plant. If left untreated, lerps can cause significant damage to the Gaura plant, leading to stunted growth and reduced vigor. In this article, we will discuss how to get rid of lerps on Gaura plants.

Identify the Problem

The first step in getting rid of lerps on Gaura plants is to identify the problem. Lerps are easy to spot as they are small, white, waxy structures that appear on the leaves and stems of the plant. They can also cause yellowing and curling of the leaves, which can be a sign that your Gaura plant is infested with lerps.

Remove Infested Leaves

The next step is to remove infested leaves from your Gaura plant. This will help prevent the spread of lerps to other parts of the plant. Use a pair of scissors or pruning shears to cut off any leaves that have lerps or show signs of damage. Be sure to dispose of them properly.
