When to prune marbled living stones in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune marbled living stones
Leave old leaves to shrivel completely. Only remove if they are entirely papery, dry, and come away with zero resistance — otherwise leave in place.
Marbled Living Stones (Lithops marmorata) need no pruning. These compact succulents self-renew each year as a new leaf pair develops inside and the old one naturally desiccates. Pruning or pulling leaves at any stage, even when they look unsightly, disrupts the plant's nutrient recycling and can introduce rot at the split point.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
