Clematis plants are beautiful and easy to care for. They come in a variety of colors and sizes, making them a popular choice for gardeners. However, slaters can be a problem for clematis plants. Slaters, also known as woodlice or pillbugs, are small crustaceans that feed on decaying plant matter. While they are not harmful to humans, they can damage clematis plants by eating the leaves and stems. Fortunately, there are several ways to get rid of slaters on clematis plants.

Identify the Problem

Before you can get rid of slaters on your clematis plant, you need to make sure that slaters are the problem. Look for small holes in the leaves and stems of your plant. You may also see slaters crawling on the plant or hiding in the soil around the base of the plant. If you are unsure whether slaters are the problem, you can take a sample of the plant to your local garden center or university extension service for identification.

Remove Debris

Slaters like to hide in dark, moist places. To discourage them from taking up residence in your clematis plant, remove any debris from around the base of the plant. This includes fallen leaves and twigs, as well as any weeds that may be growing nearby. Keep the area around the plant clean and dry.

Use Diatomaceous Earth

Diatomaceous earth is a natural powder made from the fossilized remains of diatoms, a type of algae. It is an effective way to get rid of slaters on clematis plants. Sprinkle diatomaceous earth around the base of the plant and on the leaves and stems. The powder will dry out the slaters and cause them to die.

Apply Insecticide

If diatomaceous earth does not work, you can try applying an insecticide to your clematis plant. Look for an insecticide that is labeled for use on slaters and follow the instructions carefully. Be sure to wear gloves and protective clothing when applying the insecticide, as it can be toxic to humans and pets.

Handpick the Slaters

If you only have a few slaters on your clematis plant, you can simply pick them off by hand. Wear gloves to protect your hands and dispose of the slaters in a sealed plastic bag.
