How to Get Rid of Scales on Coleus Plant

Coleus plants are a popular choice for indoor and outdoor gardening. However, like all plants, they can be susceptible to pests such as scales. Scales are small insects that attach themselves to the stems, leaves, and branches of the plant and suck out its sap, causing damage and weakening the plant. If left untreated, scales can cause serious harm to your coleus plant. In this article, we will discuss how to identify scales on your coleus plant and how to get rid of them.

Identifying Scales on Coleus Plant

Scales are small insects that are usually brown or black in color. They are about 1/8 inch long and have a hard shell-like covering that protects their bodies. Scales attach themselves to the stems, leaves, and branches of the coleus plant and suck out its sap. This causes yellowing of leaves, stunting of growth, and wilting of the plant.

Getting Rid of Scales on Coleus Plant

Getting rid of scales on your coleus plant requires a multi-step approach. Here are some steps you can take to eliminate scales from your coleus plant:

Step 1: Prune affected areas

The first step in getting rid of scales is to prune affected areas of the plant. Use sharp scissors or pruning shears to cut off any leaves or stems that have scales on them. Make sure to dispose of the affected parts properly so as not to spread the scales to other parts of the plant.

Step 2: Wash the plant

After pruning, it’s time to wash the plant thoroughly. Use a soft-bristled brush or a cloth dipped in water to gently scrub the leaves and stems of the plant. This will help remove any remaining scales that may be clinging onto the plant.

Step 3: Apply insecticidal soap

Insecticidal soap is a safe and effective way to get rid of scales on your coleus plant. Insecticidal soap works by suffocating the scales and preventing them from breathing. Follow the instructions on the package carefully and apply the soap to the affected areas of the plant. Make sure to cover all parts of the plant, including the undersides of leaves.

Step 4: Repeat treatment

Repeat the insecticidal soap treatment every week for at least three weeks. This is important because scales can lay eggs that hatch later, and you want to make sure you have eliminated all of them before they have a chance to cause more damage.
