How to Get Rid of Scales on Echinacea Plant

Updated: September 24, 2022

Echinacea, commonly known as coneflower, is a beautiful and hardy plant that is popular among gardeners. However, like most plants, it can be susceptible to pests and diseases. One common problem that gardeners face with echinacea plants is the presence of scales. Scales are small, oval-shaped insects that attach themselves to the leaves and stems of plants, sucking out their sap and causing damage. If left untreated, scales can weaken the plant and even kill it. In this article, we will discuss how to get rid of scales on echinacea plants.

Identify the Problem

The first step in getting rid of scales on echinacea plants is to identify the problem. Scales are usually found on the underside of the leaves and stems of the plant. They appear as small, brown or gray bumps that are slightly raised from the surface of the plant. If you notice these bumps on your echinacea plant, it is likely that you have a scale infestation.

Natural Remedies

There are several natural remedies that you can try to get rid of scales on echinacea plants. These include:

  • Neem oil: Neem oil is a natural insecticide that is effective against scales. Mix one tablespoon of neem oil with one quart of water and spray it onto your echinacea plant. Repeat every seven days until the scales are gone.

  • Horticultural oil: Horticultural oil is another natural insecticide that can be used to control scales on echinacea plants. Mix one tablespoon of horticultural oil with one quart of water and spray it onto your plant.

  • Alcohol: Rubbing alcohol is a simple but effective way to get rid of scales on echinacea plants. Dip a cotton swab in rubbing alcohol and apply it directly to the scales. This will kill them on contact.

Chemical Remedies

If natural remedies do not work or if you have a severe scale infestation, you may need to use chemical remedies. There are several insecticides that are effective against scales, including:

  • Malathion: Malathion is a broad-spectrum insecticide that is effective against scales. Mix one tablespoon of malathion with one gallon of water and spray it onto your echinacea plant.

  • Imidacloprid: Imidacloprid is a systemic insecticide that is absorbed by the plant and kills scales when they feed on it. Apply imidacloprid to the soil around your echinacea plant according to the instructions on the label.

Prevention

The best way to prevent a scale infestation on your echinacea plant is to keep it healthy. Make sure it is planted in well-drained soil and gets plenty of sunlight. Water it regularly but do not over-water it, as this can lead to root rot. Keep an eye out for any signs of pests or diseases and treat them promptly.
