Rusch's Living Stone problems — and how to fix them
Rusch's Living Stone (Lithops ruschiorum) 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 any out-of-season moisture
This Namib species has minimal tolerance for excess water. Strict dry summer dormancy is non-negotiable; even humidity condensing on the pot can cause problems.
Pale, washed-out appearance
While naturally pale, a very washed-out look indicates inadequate light. Maximise direct sun exposure.
Sunscorch
Despite being light-demanding, plants moved suddenly from shade to intense sun can scorch the lobe surface. Acclimatise gradually over 10-14 days.
Leaf split failure
Persistent plump old lobes in winter indicate excess moisture. Stop watering and allow the old tissue to desiccate naturally.
Mealybugs
The white lobe surface can make mealybug masses less visible. Inspect the central cleft and soil level regularly and treat with isopropyl alcohol.
