Coral bells, also known as Heuchera, are a popular perennial plant prized for their colorful foliage and delicate bell-shaped flowers. However, like all plants, they are susceptible to diseases that can harm their growth and appearance. In this article, we will discuss some of the most common coral bells plant diseases, how to identify them, and what steps you can take to treat and prevent them.
Leaf Spot
Leaf spot is a fungal disease that causes small, circular spots on the leaves of coral bells. These spots can be brown, black, or red and may have a yellow halo around them. As the disease progresses, the spots can merge and cause the leaves to turn yellow or brown and eventually die.
To treat leaf spot, remove any infected leaves and dispose of them in the trash. Avoid overhead watering or getting water on the leaves. Fungicides can also be used to control the disease.
Powdery Mildew
Powdery mildew is a fungal disease that causes a white or grayish powdery coating on the leaves of coral bells. This coating can make the leaves look dusty or frosted. As the disease progresses, the leaves can become distorted and stunted.
To treat powdery mildew, remove any infected leaves and dispose of them in the trash. Increase air circulation around the plant by spacing them out or placing a fan nearby. Fungicides can also be used to control the disease.
Crown Rot
Crown rot is a fungal disease that affects the base of coral bells where they meet the soil. It causes the crown to become soft and mushy, causing the plant to wilt and die.
To prevent crown rot, avoid overwatering and ensure that the soil is well-draining. Remove any dead foliage around the base of the plant to improve airflow.
Rust
Rust is a fungal disease that causes orange or yellow spots on the leaves of coral bells. As the disease progresses, the spots can merge and cause the leaves to turn brown and fall off.
To treat rust, remove any infected leaves and dispose of them in the trash. Fungicides can also be used to control the disease.
Bacterial Leaf Spot
Bacterial leaf spot is a bacterial disease that causes small, water-soaked spots on the leaves of coral bells. These spots can be surrounded by a yellow halo and eventually turn brown or black. The disease can cause the leaves to become distorted or drop prematurely.
To treat bacterial leaf spot, remove any infected leaves and dispose of them in the trash. Avoid overhead watering or getting water on the leaves. Copper-based fungicides can also be used to control the disease.
