Chinese Dunce Cap problems — and how to fix them
Chinese Dunce Cap (Orostachys iwarenge) 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
Water collecting in the center of the flat rosette, especially in cool damp conditions, leads to rapid fungal rot. Position the plant at a slight angle outdoors, water only at the soil level, and ensure excellent airflow around the rosette.
Confusion over 'death' after flowering
Orostachys is monocarpic — each rosette dies after producing its flowering spike. This is natural and not a care failure. The mother rosette produces several offsets beforehand; pot these up separately to continue the plant.
Slugs and snails outdoors
The flat, fleshy rosette is attractive to slugs and snails in damp weather. Use copper tape around containers, iron phosphate slug pellets (wildlife-safe), or remove by hand at night.
