Copiapoa hypogaea problems — and how to fix them
Copiapoa hypogaea (Copiapoa hypogaea) 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 rot from overwatering
The thickened root rots easily in damp soil. Water minimally, only when bone-dry, and keep nearly dry in winter; use a sharp mineral mix.
Greening and swelling
In low light or with excess water the body turns green, plumps up and loses its sunken desert character. Increase light and reduce watering.
Body retracting (misread as decline)
Pulling below the soil line in drought is a healthy water-saving response, not rot. Confirm firmness before reacting; resume light watering in growth.
Mealybugs
White cottony pests hide in the woolly crown and at the soil line. Inspect the apex and root collar and treat with a systemic insecticide.
