Troubleshooting
Shand's Gibbaeum problems — and how to fix them
Shand's Gibbaeum (Gibbaeum shandii) 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
The most common killer. Caused by overwatering or poorly draining soil, especially during summer dormancy. Remove affected roots, dust with sulphur, and repot into fresh dry grit mix. Withhold water for two weeks.
Etiolation (stretching)
Occurs when light is insufficient. The lobes elongate and lose their compact habit. Move to the brightest possible position; stretched growth cannot be reversed but new lobes will form correctly.
Mealybugs
White waxy clusters appear between the lobes and at soil level. Treat with isopropyl alcohol applied with a cotton swab, or a systemic insecticide. Inspect regularly as infestations hide in leaf crevices.
