Chanet's Dunce Cap problems — and how to fix them
Chanet's Dunce Cap (Orostachys chanetii) 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.
Root and crown rot
The most common issue, caused by overwatering or poorly draining soil. Rosette centre turns mushy and black. Remove affected tissue, allow to dry, and repot in fresh, gritty mix.
Etiolation (stretching)
In low light the rosette elongates and loses its compact form. Move to a brighter position; etiolated growth cannot be reversed but new growth will be tighter.
Mealybugs
White cottony clusters appear at the base of leaves or in the rosette centre. Treat with isopropyl alcohol on a cotton swab or a dilute neem-oil spray.
