Bleeding heart plants are a beautiful addition to any garden, known for their delicate, heart-shaped flowers. However, they are susceptible to various pests that can damage their foliage and flowers. Identifying these pests early and implementing effective control measures is essential to maintaining healthy bleeding hearts.
Common Pests That Affect Bleeding Heart
Aphids
Aphids are small, soft-bodied insects that cluster on new growth, sucking sap and causing distorted leaves and stunted growth. They often produce a sticky substance called honeydew, which can lead to sooty mold.
Slugs and Snails
Slugs and snails are common pests that feed on the leaves and stems of bleeding hearts, leaving irregular holes and slime trails. They are especially active during damp, cool nights.
Spider Mites
Spider mites are tiny arachnids that spin fine webs on the undersides of leaves. They cause stippling or speckling on foliage and can lead to leaf drop if infestations are severe.
