Troubleshooting
Broad-leaved Helleborine problems — and how to fix them
Broad-leaved Helleborine (Epipactis helleborine) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Slug and snail damage
Emerging shoots and young stems are attractive to slugs and snails in spring; apply organic slug deterrent around the clump as shoots appear in early spring, and avoid disturbing the surrounding soil where eggs overwinter.
Failure to establish or re-emerge
Broad-leaved helleborine relies on specific mycorrhizal soil fungi — bare-root divisions can fail if the fungal network is broken, and transplanting into sterilised or nutrient-poor potting compost is usually fatal; always move divisions with a good ball of undisturbed root soil.
