Troubleshooting
Dwarf Crocus problems — and how to fix them
Dwarf Crocus (Crocus minimus) 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.
Corm rot (summer)
Its small size and Corsican/Sardinian origin make it especially sensitive to summer moisture. Ideal in an alpine house, cold frame with summer cover, or raised gravel bed where corms can dry completely.
Wind damage
The tiny flowers are easily shredded by cold spring winds. Plant in a sheltered, south-facing spot — a wall or rock crevice provides the wind protection and reflected warmth this Mediterranean species needs.
Slow multiplication
Unlike the large Dutch crocuses, C. minimus multiplies slowly. Grow from seed sown fresh in gritty compost each summer to build up stock; seedlings flower in 3–4 years.
