When to prune lithops pseudotruncatella 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 lithops pseudotruncatella
Wait until old leaf bodies are completely dried and papery, then peel the husk away gently to expose the new pair. Do not cut, water, or disturb the plant during its summer dormancy.
Lithops pseudotruncatella (living stones) requires no pruning. Old leaf pairs naturally shrivel and dry as the new pair pushes through from within. Never cut or remove the old leaves until they are fully desiccated and papery — early removal can damage the new growth forming inside.

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.
