Troubleshooting
Chin Cactus problems — and how to fix them
Chin Cactus (Gymnocalycium schickendantzii) 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
Overwatering or standing water causes the base to collapse. Remove from wet soil, allow roots to air-dry for a day, trim any rotten roots, and repot in fresh gritty mix. Withhold water for 2 weeks after repotting.
Sunscorch
Pale yellow or orange patches on the sun-facing side of the stem indicate excessive direct sun. This species needs shading from intense summer afternoon sun. Move to filtered light and the discoloration should not worsen.
Scale insects
Brown, barnacle-like bumps cling to the ribs and tubercles. Scrape off with a soft brush and treat with diluted neem oil or horticultural oil spray; repeat after two weeks.
