Troubleshooting
Purple Heartleaf Bergenia problems — and how to fix them
Purple Heartleaf Bergenia (Bergenia cordifolia 'Purpurea') 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.
Vine weevil
Grubs attack rhizomes from late summer; adult notching on leaf margins signals infestation. Apply pathogenic nematodes (Steinernema kraussei) in late summer while soil is warm and moist. Particularly damaging in container cultivation.
Leaf scorch
Large leaves are susceptible to scorch in full sun during hot, dry summers, especially in zones 6–8. Relocate to a partially shaded position or ensure consistent summer irrigation. Remove damaged leaves at the base.
Slug damage
Emerging spring foliage and flower stems are attractive to slugs. Apply iron phosphate-based pellets or use physical barriers. Damage is typically cosmetic on established plants; protect young divisions diligently.
