Updated: June 28, 2022

Cuphea plants are a beautiful addition to any garden, with their vibrant colors and unique shape. However, like all plants, they can be susceptible to fungal infections which can damage their appearance and health. Here are some tips on how to get rid of fungus on your Cuphea plant:

Identify the Fungus

Before you start treating your Cuphea plant for fungus, it is important to identify the type of fungus that is affecting it. There are several different types of fungal infections that can affect Cuphea plants, including powdery mildew, rust, and leaf spot.

Powdery mildew appears as a white powdery substance on the leaves and stems of the plant. Rust appears as orange or brown spots on the leaves, while leaf spot appears as small spots that are usually yellow or brown in color.

Remove Infected Leaves

Once you have identified the type of fungus affecting your Cuphea plant, the first step in getting rid of it is to remove any infected leaves. This will help prevent the spread of the fungus to other parts of the plant.

Using a pair of clean scissors or pruning shears, carefully cut off any leaves or stems that show signs of infection. Be sure to dispose of these infected parts in a sealed plastic bag to prevent the spread of spores.

Improve Air Circulation

Fungal infections thrive in warm, humid conditions with poor air circulation. To prevent the growth and spread of fungus on your Cuphea plant, it is important to improve air circulation around the plant.

This can be achieved by pruning back any overgrown branches or foliage that may be blocking air flow. You can also move the plant to a location with better air circulation or use a fan to increase air flow around the plant.

Use Fungicides

If removing infected leaves and improving air circulation does not solve the problem, you may need to use a fungicide to get rid of the fungus on your Cuphea plant.

There are several different types of fungicides available, including organic and chemical options. Be sure to read the label carefully and follow the instructions for application.

Water Carefully

Overwatering can also contribute to fungal growth on Cuphea plants. To prevent this, be sure to water your plant carefully and only when necessary.

Allow the soil to dry out slightly between waterings and avoid getting water on the leaves of the plant. Water at the base of the plant, rather than from above.
