When to prune schwantes' living stones in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune schwantes' living stones
Do not cut, trim, or pull leaves. The only intervention needed is gently removing the fully dry, papery remnant of the old leaf pair once the new pair is fully formed and the old tissue is completely desiccated.
Schwantes' Living Stones (Lithops schwantesii) need no pruning whatsoever. The annual renewal of the leaf pair is a self-contained process in which the old leaves shrivel and supply the developing new pair with moisture and nutrients. Cutting or pulling any part of the plant before this is complete will stress or damage it.

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.
