Dealing with Bleeding Heart Plant Diseases:
Identification and Treatment

Updated: March 27, 2023

Bleeding heart plants are iconic beauties in the garden. They have delicate, heart-shaped flowers that dangle gracefully from arching stems, adding a touch of elegance to any landscape design. However, like any other plant, bleeding hearts are susceptible to diseases that can compromise their health and beauty. Here’s a guide to identifying and treating common bleeding heart plant diseases.

Common Bleeding Heart Plant Diseases

1. Leaf Spots

Leaf spots are one of the most common bleeding heart plant diseases. The fungal disease manifests as circular or irregular-shaped spots on the leaves, ranging in color from yellow to brown. The spots may have a darker border and may merge together, leading to leaf death.

2. Crown Rot

Crown rot is a serious fungal infection that can lead to the death of the entire plant. It affects the base of the plant, causing it to rot and turn mushy. The disease can spread quickly throughout the plant, leaving it wilted and stunted.

3. Powdery Mildew

Powdery mildew is a fungal disease that appears as a white powdery coating on the leaves, stems, and flowers of bleeding heart plants. If left untreated, it can cause the leaves to deform and turn yellow or brown.

4. Verticillium Wilt

Verticillium wilt is a soil-borne fungal disease that infects bleeding heart plants through the roots. It causes wilting and yellowing of leaves, stunting growth, and eventually leads to the death of the entire plant.

Treatment Options for Bleeding Heart Plant Diseases

1. Fungicides

Fungicides are chemical treatments that can help control fungal infections in bleeding heart plants. They work by killing or inhibiting the growth of fungi that cause diseases such as leaf spots, crown rot, powdery mildew, and verticillium wilt. You can find fungicides in liquid or powder form at your local garden center.

2. Cultural Practices

Cultural practices such as proper watering, pruning, and soil management can help prevent bleeding heart plant diseases. Overwatering can cause root rot and crown rot, so make sure not to water your plants too frequently or too much. Pruning infected parts of the plant can also help prevent diseases from spreading. Ensure that you remove any dead or decaying foliage around the base of the plant to prevent fungal growth.

3. Biological Controls

Biological controls such as beneficial microbes and predators can also help control bleeding heart plant diseases naturally. Beneficial microbes such as mycorrhizae fungi form a mutually beneficial relationship with bleeding heart plants, improving their nutrient absorption and disease resistance capabilities. Predators like ladybugs feed on pests that may spread diseases to your plants.
