Bruch's Chin Cactus problems — and how to fix them
Bruch's Chin Cactus (Gymnocalycium bruchii) 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 in winter
Cool temperatures plus any residual moisture cause rapid rot. Keep almost completely dry from October to February.
Failure to flower
Ensure adequate light and a proper cool, dry winter rest. Young plants (under 2 years) may not yet be mature enough to flower.
Mealybugs
White cottony deposits at stem bases and between spines. Remove with alcohol-dipped cotton buds and treat with insecticidal soap.
Pale, yellowish stems
Insufficient light or very high summer temperatures. Provide bright indirect light and protect from extreme heat.
Crown rot
Usually follows overwatering or water sitting in the crown. Water at the base only and ensure excellent drainage.
