Troubleshooting
Hardy Cyclamen problems — and how to fix them
Hardy Cyclamen (Cyclamen hederifolium) 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
Caused by planting too deep or overwatering during summer dormancy. Plant shallowly and keep the tuber dry while dormant.
Botrytis (grey mould)
Fuzzy grey growth on leaves and stems in damp, stagnant conditions. Improve airflow and remove faded flowers and yellowing leaves promptly.
Vine weevil
Larvae hollow out the tuber, especially in containers. Inspect roots when repotting and treat with biological nematodes.
Failure to flower
Usually too much shade, summer watering disturbing dormancy, or buried tubers. Give a dry rest and a shallow planting depth.
