Troubleshooting
White Bleeding Heart problems — and how to fix them
White Bleeding Heart (Dicentra spectabilis 'Alba') 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.
Premature summer dormancy
Foliage yellows and collapses in midsummer heat, especially in USDA zones 7-9 or in dry conditions. Pair with neighbouring plants (hostas, astilbe, ferns) to fill the gap. This is normal and not a disease — water well in spring to prolong the season.
Slug and snail damage
Emerging spring shoots are vulnerable to slugs. Apply organic slug pellets (ferric phosphate) or use copper barriers around crowns. Damage typically appears as ragged holes in young foliage and stems.
Crown rot in wet winter soils
Waterlogged soil in winter causes rhizome rot. Ensure excellent drainage at planting by raising beds or incorporating grit. In heavy clay, grow in raised beds or containers. Affected crowns show soft, brown, foul-smelling tissue.
