Troubleshooting
Common Snowdrop problems — and how to fix them
Common Snowdrop (Galanthus nivalis) 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.
Dry bulb failure
Snowdrop bulbs sold dry in autumn often establish poorly because they desiccate rapidly. Purchase or transplant 'in the green' immediately after flowering in February–March for significantly better results.
Grey mould (Botrytis galanthina)
A specific botrytis strain affects snowdrops, causing rotting of bulbs and dying foliage in wet, cold conditions. Remove and bin affected plants and soil; do not compost. Improve drainage and avoid overcrowding.
Narcissus fly (Merodon equestris)
Larvae burrow into bulbs during summer dormancy, hollowing them out. Rake the soil surface after foliage dies back to deter adult flies from laying eggs near bulbs; cover small plantings with fine netting in early summer.
Prevent common snowdrop problems before they start
Most common snowdrop issues are care-mismatch, not bad luck. Dial in the basics:
