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.
Root rot from summer watering
The most common cause of death. The plant must be kept completely dry during summer dormancy (late spring to early autumn). Any moisture during dormancy rapidly leads to fungal rot at the roots and base.
Sunscorch or bleaching
Intense midday summer sun causes the bodies to turn pale, yellow, or develop orange-brown scorch patches. Provide light shade during the hottest part of the day in summer, or move the pot slightly back from south-facing glass.
Failure to flower
Flowers are triggered by the return of watering in autumn after a correct dry summer rest and adequate bright light. Plants kept too warm, too wet, or in low light year-round rarely flower.
