Bleeding-Heart Plants: A Guide to Pests and Control
Bleeding-heart (Dicentra spectabilis) is a beautiful perennial that adds a touch of color and charm to shady spots in your garden. However, this popular plant can be susceptible to a variety of pests that can damage its leaves, stems, and flowers.
Common Pests of Bleeding-Heart Plants
Aphids
Aphids are tiny, green or black bugs that suck the sap from bleeding-heart plants. They are often found in large numbers on stems or the undersides of leaves. A heavy infestation of aphids can weaken and even kill a bleeding-heart plant.
Scale
Scale insects look like small, waxy bumps on plant stems and leaves. They are actually insects that are protected by a hard outer shell. Like aphids, scale insects suck the sap from bleeding-heart plants, causing damage.
Slugs and Snails
Slugs and snails are soft-bodied creatures that chew ragged holes through leaves. They are most active during the nighttime hours and leave behind a slimy trail.
Controlling Pests on Bleeding-Heart Plants
Aphids and Scale
Aphids and scale insects can be controlled with insecticidal soap spray, horticultural oil, or neem oil. These products effectively kill the pests without harming beneficial insects.
Slugs and Snails
Slugs and snails can be difficult to control, but there are a few effective methods. One way is to handpick the pests at night when they are most active. You can also use slug bait or diatomaceous earth to kill them.
Tips for Preventing Pests on Bleeding-Heart Plants
In addition to using pest control methods, there are a few things you can do to help prevent pests from infesting your bleeding-heart plants:
- Keep the area around your plants free of leaves and other debris where pests like to hide.
- Limit mulch to 3 inches (8 cm) or less around your plants.
- Avoid using chemical insecticides, which can kill beneficial insects that help control pests.
