Marbled Living Stones problems — and how to fix them

Marbled Living Stones (Lithops marmorata) 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.

Body splitting from overwatering

Giving water when the plant is already full — particularly in spring or early summer — causes the body to split abnormally, creating entry points for bacteria and rot. If the body splits without a new leaf pair emerging, it is almost always due to excess water.

Persistent old leaf sheaths

If old leaf sheaths remain plump and fail to collapse after several months, water may have been given too late in the season, slowing the cycle. Withhold water entirely until the sheaths become completely papery.

Fungal gnats

Fungus gnats are attracted to any residual organic matter in the soil. Using a predominantly mineral mix and a fine gravel top-dressing largely prevents them. Yellow sticky traps can be used to monitor and catch adults.
