Troubleshooting
Chin Cactus problems — and how to fix them
Chin Cactus (Gymnocalycium baldianum) 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.
Failure to flower
Usually from a warm, watered winter. Give a cool, dry, bright dormancy from late autumn to set the summer buds.
Root rot
From a wet, poorly drained mix. Use gritty soil and a drainage hole, water only when fully dry, and keep dry in winter.
Red spider mites
Stippling and webbing in hot dry air. Improve airflow and treat promptly; inspect the body under the spines.
Sun scorch
Bleached or corky patches from sudden strong sun. Acclimatise gradually and shade from intense midday summer light.
