Florist's Cyclamen problems — and how to fix them
Florist's Cyclamen (Cyclamen persicum) 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.
Crown rot
Caused by overwatering or water pooling on the corm. Water from below and ensure excellent drainage.
Yellow leaves
Often natural dormancy onset in late spring; can also signal overwatering, too much heat, or root-bound conditions.
Failure to rebloom
The plant needs a cool dry rest period (summer dormancy) and a gradual temperature drop in autumn to trigger reflowering.
Botrytis grey mould
Poor air circulation in damp conditions encourages fungal growth. Remove dead flowers promptly and improve ventilation.
Vine weevil
Larvae feed on the corm. Check roots at repotting; treat with biological nematodes (Steinernema kraussei) in autumn.
