If you are a lavender enthusiast, you know how frustrating it can be to find scales on your French lavender plant. These small insects can quickly destroy the plant and leave you with a wilted and weakened lavender plant. However, with the right methods, you can get rid of scales and save your French lavender plant. In this article, we will discuss how to get rid of scales on French lavender plants.
What are Scales?
Scales are small, sap-sucking insects that attach themselves to the stems and leaves of plants. They can be found on all parts of the plant, including the roots. Scales are usually tiny and difficult to see with the naked eye, but they leave behind a sticky substance called honeydew that attracts ants and other insects.
Signs of Scale Infestation
The first sign of a scale infestation is usually the presence of honeydew on the leaves and stems of the French lavender plant. You may also notice a black, sooty mold growing on the honeydew. The leaves may turn yellow or brown and drop prematurely. If left untreated, scales can kill your French lavender plant.
How to Get Rid of Scales on French Lavender Plant
1. Prune Infested Areas
The first step in getting rid of scales is to prune any infested areas of the French lavender plant. Use clean, sharp pruning shears to remove all affected leaves and stems. Be sure to dispose of them properly to prevent further spread of the scales.
2. Use Horticultural Oil Spray
Horticultural oil spray is an effective way to get rid of scales on French lavender plants. The oil suffocates the insects by coating their bodies and blocking their breathing pores. To apply horticultural oil spray, mix one tablespoon of oil with one quart of water in a spray bottle. Spray the solution on the entire plant, focusing on the areas where scales are present. Repeat the process every two weeks until the scales are gone.
3. Use Insecticidal Soap
Insecticidal soap is another effective way to get rid of scales on French lavender plants. The soap works by breaking down the outer layer of the insects, causing them to dehydrate and die. To apply insecticidal soap, mix one tablespoon of soap with one quart of water in a spray bottle. Spray the solution on the entire plant, focusing on the areas where scales are present. Repeat the process every two weeks until the scales are gone.
4. Use Neem Oil
Neem oil is a natural insecticide that can be used to get rid of scales on French lavender plants. It works by disrupting the life cycle of the insects and preventing them from reproducing. To apply neem oil, mix one tablespoon of oil with one quart of water in a spray bottle. Spray the solution on the entire plant, focusing on the areas where scales are present. Repeat the process every two weeks until the scales are gone.
