Troubleshooting
Miniature Cone Plant problems — and how to fix them
Miniature Cone Plant (Conophytum minimum) 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.
Summer rot
The most critical risk — any moisture during the dry summer rest period causes rapid fatal rot. Keep completely dry from April through August.
Bodies not emerging in autumn
Caused by insufficient summer drought or insufficient light in prior seasons. Check watering schedule and light exposure.
Mealybugs
Extremely difficult to spot among the tiny bodies. Check under magnification and treat with dilute isopropyl alcohol.
Etiolation
Elongated, domed bodies indicate insufficient sun. Maximise direct light immediately.
Collar rot
Water pooling at the base between bodies causes rot. Water sparingly from the base using a fine-nozzle watering can.
