Troubleshooting
Spring Cyclamen problems — and how to fix them
Spring Cyclamen (Cyclamen repandum) 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.
Tuber rot
Poor drainage or waterlogging during summer dormancy is the primary cause. Lift tubers or improve soil drainage if growing outdoors in wet climates.
Slugs and snails
Emerging young leaves are vulnerable in spring. Use organic slug pellets (ferric phosphate) or physical barriers.
Failure to naturalise
Needs undisturbed alkaline, well-drained soil under deciduous canopy. Acidic or waterlogged soils prevent establishment.
Fading flower colour
In too much sun, flowers bleach quickly. Move to deeper shade for longer-lasting blooms.
Dormancy mistaken for death
Leaves die back completely in summer; the tuber is dormant, not dead. Avoid disturbing or overwatering during this period.
