Autumn Crocus problems — and how to fix them
Autumn Crocus (Crocus speciosus) 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.
Confusion with toxic Colchicum
Colchicum autumnale (meadow saffron) shares the 'autumn crocus' name but is severely toxic — it has 6 stamens vs. 3 in true Crocus. True Crocus speciosus has 3 stamens and belongs to Iridaceae.
Corm rot in storage or wet soils
Corms planted in poorly drained ground or stored in damp conditions rot readily. Plant in gritty soil, ensure sharp drainage, and keep summer-dormant corms dry.
Squirrel and rodent predation
Freshly planted corms are highly attractive to squirrels and rodents. Use wire mesh laid over the planting area, or plant corms in wire baskets.
Prevent autumn crocus problems before they start
Most autumn crocus issues are care-mismatch, not bad luck. Dial in the basics:
