Living Stones problems & how to fix them

Lithops lesliei

Drooping, yellowing, brown tips, or a plant that just won’t thrive? Here are the most common Living Stones problems, what usually causes them, and how to turn things around.

Common problems

Root rot

A single overwatering at the wrong season can burst or rot the leaf bodies. A fungal or bacterial infection of the roots, almost always triggered by soil staying wet too long. Caught early, most plants recover within a few weeks after repotting; if most roots are already mushy, recovery is uncertain.

Overwatering

Watering during the winter leaf-change makes plants absorb both pairs and collapse. The soil is staying wet longer than the plant can handle, starving roots of oxygen. If caught before roots start rotting, the fix is simple - let the soil dry out and adjust the routine - and most plants bounce back within 2-3 weeks.

Etiolation (insufficient light)

In weak light the bodies elongate above the soil line and rarely recover their shape. The plant is stretching toward light it isn't getting: long gaps between leaves, pale thin growth, and leaning. Stretched growth never compacts again, but with more light all new growth comes in full and sturdy - the plant's future is good.

Fungus gnats

Gnats indicate the mix stays moist far too long for a Lithops. Small dark flies that breed in constantly moist potting soil; the adults are harmless but annoying, while larvae can nibble roots of seedlings and weak plants. Very treatable by drying out the soil; expect the flies to fade over 2-3 weeks.

The mistakes that most often kill it

Watering on a schedule instead of following the leaf-change cycle.
Any watering while the old leaves are being absorbed.
Rich organic potting soil, which holds water these plants cannot handle.
