How to Get Rid of Scales on Clematis Plant

Updated: May 2, 2022

Clematis is a beautiful and popular flowering plant that can add color and interest to any garden. However, like any other plant, it is susceptible to pests and diseases, including scales. Scales are tiny insects that suck the sap from the plant, causing it to weaken and eventually die. If you notice scales on your clematis plant, it’s important to take action right away to prevent further damage. In this article, we’ll discuss how to get rid of scales on clematis plants.

Identify the Scales

The first step in getting rid of scales is to identify them. Scales are small, oval-shaped insects that are usually brown or black. They can be found on the stems, leaves, and flowers of the clematis plant. Sometimes they can be mistaken for part of the plant or even dirt.

Remove the Infected Plant Parts

Once you have identified the scales, you need to remove the infected plant parts. Use a pair of sharp pruners or scissors to cut off the affected stems or leaves. Be sure to dispose of them properly so that the scales don’t spread to other plants in your garden.

Use Natural Remedies

There are several natural remedies that you can use to get rid of scales on clematis plants. One effective method is to use neem oil. Mix one tablespoon of neem oil with one gallon of water and spray it onto the affected parts of the plant. Neem oil is a natural insecticide that works by suffocating the scales.

Another effective natural remedy is insecticidal soap. Mix one tablespoon of insecticidal soap with one quart of water and spray it onto the affected parts of the plant. Insecticidal soap works by disrupting the cell membranes of the scales, causing them to die.

Use Chemical Insecticides

If natural remedies don’t work, you may need to use chemical insecticides. Be sure to choose an insecticide that is labeled for use on clematis plants and follow the instructions carefully. Some common insecticides for scale control include malathion, imidacloprid, and acephate.

Prevent Future Infestations

Once you have gotten rid of the scales, it’s important to take steps to prevent future infestations. One way to do this is to keep your clematis plant healthy and strong. Make sure it gets enough water and nutrients, and prune it regularly to promote air circulation.

You can also use sticky traps to catch any scales that may try to infest your plant. Place the traps around the base of the plant or on the stems.


Scales can be a serious problem for clematis plants, but with the right treatment, you can get rid of them and prevent future infestations. Remember to identify the scales, remove infected plant parts, use natural remedies or chemical insecticides as needed, and take steps to prevent future infestations.


Can scales spread to other plants?

Yes, scales can spread to other plants in your garden. That’s why it’s important to remove infected plant parts and take steps to prevent future infestations.

Will neem oil harm beneficial insects?

No, neem oil is safe for beneficial insects such as bees and ladybugs.

How often should I apply insecticide?

Follow the instructions on the label of the insecticide you are using. In general, you may need to apply it every seven to fourteen days until the scales are gone.
