Bleeding Heart problems — and how to fix them
Bleeding Heart (Dicentra spectabilis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Early die-back
Foliage yellows and collapses by midsummer — this is the plant's normal summer dormancy, not a disease. Interplant with hostas, ferns, or astilbes to fill the gap. Avoid disturbing the dormant roots when planting around them.
Root and crown rot
Caused by waterlogged soil, particularly in cold, wet winters. Ensure free-draining conditions by incorporating grit into heavy soils. Apply a coarse mulch around crowns for winter drainage. Affected plants rarely recover; replant in a better-drained site.
Aphid infestations
Soft spring stems are attractive to aphids, which cluster on new growth and flower stems. Knock off with a strong water jet or apply insecticidal soap. Encourage beneficial insects such as ladybirds and lacewings to aid natural control.
