Troubleshooting
Giant Snowdrop problems — and how to fix them
Giant Snowdrop (Galanthus elwesii) 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.
Poor establishment from dry bulbs
Like all snowdrops, G. elwesii bulbs desiccate in storage and often establish poorly when planted dry in autumn. Plant 'in the green' after flowering in late winter for best results; if using dry bulbs, plant immediately on receipt and water in well.
Leaf blotch and grey mould
Botrytis galanthina and Stagonospora curtisii can cause grey or tan blotches on leaves and flower scapes, especially in cool, wet weather. Remove affected material and avoid overhead irrigation; good air circulation is preventive.
Slugs and snails
Emerging leaves and flower buds in late winter are vulnerable to slug damage. Apply organic pellets (ferric phosphate) around emerging shoots; the early season means populations are often lower, but mild winters worsen the problem.
Prevent giant snowdrop problems before they start
Most giant snowdrop issues are care-mismatch, not bad luck. Dial in the basics:
