Troubleshooting
Gibbaeum petrense problems — and how to fix them
Gibbaeum petrense (Gibbaeum petrense) 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.
Rot in the cushion
Dense clusters trap moisture; wet mix or poor airflow causes soft brown patches. Keep nearly dry in summer and grow with good ventilation.
Stretched, soft leaves
Insufficient light loosens the tight cushion habit. Relocate to a full-sun position to firm up growth.
Failure to flower
No bloom usually means too little light or watering at the wrong season. Provide strong sun and water during the cool autumn-spring growth window.
Root mealybugs
Hidden in the root zone, causing slow decline. Check roots at repotting and treat with a systemic or alcohol drench if found.
