How to Get Rid of Fungus on Chrysanthemum Plant

Updated: December 23, 2022

Chrysanthemums are beautiful flowers that come in a wide range of colors and sizes. They are a favorite among gardeners for their ease of cultivation and the variety of blooms they produce. However, like any other plant, chrysanthemums are not immune to fungal infections. Fungus can cause a lot of damage to your plant if left unchecked. Here are some tips on how to get rid of fungus on chrysanthemum plants.

Identify the type of fungus

Identifying the type of fungus is crucial in deciding the best course of action to take. Some common types of fungal infections that affect chrysanthemum plants are powdery mildew, black spot, and grey mold. Each type of fungus has unique characteristics, such as color, texture, and shape.

Remove the infected parts

Once you have identified the type of fungus affecting your chrysanthemums, the next step is to remove the infected parts. This includes leaves, stems, and flowers. Make sure you use a sharp pair of pruning shears to make clean cuts. Dispose of the infected parts in a sealed plastic bag or burn them.

Improve air circulation

Fungal infections thrive in humid environments with poor air circulation. To prevent further infections, ensure that your chrysanthemum plants have good air circulation. You can do this by spacing out your plants adequately and avoiding overcrowding.

Water properly

Overwatering can cause fungal infections in chrysanthemums. Water your plants at the base instead of overhead to avoid wetting the leaves and flowers. Also, avoid watering at night as this can cause water to sit on the leaves for an extended period.

Use fungicides

Fungicides are chemical substances that kill or prevent the growth of fungi. There are many fungicides available in the market, and it’s essential to choose one that’s suitable for your chrysanthemums. Always follow the instructions on the label and wear protective gear such as gloves and a mask when applying fungicides.

Keep the soil healthy

Fungi thrive in unhealthy soil. Ensure that you use well-draining soil that’s rich in nutrients. You can also add organic matter such as compost to improve the soil’s health.

Frequently monitor your plants

The key to preventing fungal infections is early detection. Regularly inspect your chrysanthemum plants for any signs of fungal infections. This includes yellowing leaves, spots on leaves, and wilting flowers.

By following these tips, you can get rid of fungus on your chrysanthemum plants and keep them healthy.
