How to Get Rid of Scales on Coffee Tree Plant

Coffee tree plants are a popular houseplant due to their ability to thrive indoors and produce coffee beans. However, one issue that often plagues these plants is the presence of scales. Scales are small, flat insects that attach themselves to the stems and leaves of plants and suck out their sap, causing damage and even death if left unchecked. In this article, we will discuss how to get rid of scales on coffee tree plants.

Identify the Scales

The first step in getting rid of scales on your coffee tree plant is to identify them. Scales can be difficult to spot as they often blend in with the plant’s stems and leaves. However, there are a few telltale signs that you can look out for.

• Look for small, circular or oval-shaped bumps on the stems and leaves of your coffee tree plant.
• Check for a sticky substance, known as honeydew, on your plant’s foliage.
• Look for any signs of wilting or yellowing leaves.

If you spot any of these signs, it’s likely that your coffee tree plant has scales.

Remove Infected Leaves

Before you begin treating your coffee tree plant for scales, it’s important to remove any infected leaves or stems. This will help prevent the scales from spreading to other parts of the plant.

• Using a pair of sharp scissors or pruning shears, carefully remove any leaves or stems that have visible scales on them.
• Be sure to dispose of these infected parts in a sealed plastic bag and throw them away in the trash.

Treat with Horticultural Oil

After removing any infected parts from your coffee tree plant, it’s time to treat it with horticultural oil. Horticultural oil is a natural oil that suffocates and kills scales without harming your plant.

• Mix one tablespoon of horticultural oil with one quart of water in a spray bottle.
• Spray the solution onto your coffee tree plant, making sure to cover all the stems and leaves.
• Repeat this process every seven to ten days until all scales have been eliminated.

Use Neem Oil

Another natural solution for getting rid of scales on your coffee tree plant is neem oil. Neem oil is derived from the seeds of the neem tree and is known for its insecticidal properties.

• Mix one tablespoon of neem oil with one quart of water in a spray bottle.
• Spray the solution onto your coffee tree plant, making sure to cover all the stems and leaves.
• Repeat this process every seven to ten days until all scales have been eliminated.

Use Chemical Pesticides as a Last Resort

If natural solutions don’t work, you may need to use chemical pesticides as a last resort. However, it’s important to note that these pesticides can be harmful to both your plant and the environment.

• Choose a pesticide that is labeled for use on houseplants and contains active ingredients such as imidacloprid or acephate.
• Follow the instructions on the label carefully, making sure to wear gloves and protective clothing when applying the pesticide.
• Keep your coffee tree plant away from children and pets until the pesticide has dried and the area has been ventilated.
