Golden Crocus problems — and how to fix them
Golden Crocus (Crocus chrysanthus) 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.
Squirrel and rodent predation
Squirrels, mice, and voles readily dig up and eat corms. Plant in wire-mesh cages sunk below soil level, or cover newly planted areas with chicken wire just below the soil surface and remove once foliage appears. C. chrysanthus is somewhat less squirrel-resistant than C. tommasinianus.
Botrytis and corm rot
Grey mould (Botrytis) and fungal corm rots occur in poorly draining or waterlogged soil. Plant in sharply draining soil with added grit; immediately remove any plants showing rotted stems at soil level.
Failure to naturalise in lawns
Premature mowing of foliage prevents corms from storing energy for the next season. Do not mow the area where crocuses are planted until leaves have yellowed and died back naturally — usually 6 weeks after flowering ends.
Prevent golden crocus problems before they start
Most golden crocus issues are care-mismatch, not bad luck. Dial in the basics:
