Troubleshooting
Lapidaria margaretae problems — and how to fix them
Lapidaria margaretae (Lapidaria margaretae) 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 from overwatering
The most common killer. Watering in summer dormancy or in a moisture-retentive mix turns the body mushy and yellow-brown. Keep it dry during rest and use a fast-draining mineral medium.
Etiolation / stretching
Insufficient light makes the leaf pairs elongate and pale, losing their pebble shape. Move to the brightest available window or add a grow light.
Split or burst leaves
Watering an old leaf pair too generously, especially out of season, can cause it to split. Water sparingly and let the new leaf pair draw moisture from the old one.
Mealybugs and root mealybugs
White cottony pests hide in the leaf cleft and on roots. Inspect at repotting, isolate new plants, and treat with 70% isopropyl alcohol on a cotton swab.
