When to prune lithops lesliei 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 lesliei
Peel away only fully desiccated, papery old leaf husks by hand — never cut or pull firm fleshy leaves. Remove spent flower stalks cleanly at the base once blooming is finished.
Lithops lesliei (living stones) need no pruning. Each year the old leaf pair naturally shrivels, feeding the new pair as it emerges — intervening early harms the plant. Remove only fully dried, papery husks after the new leaves are completely developed. Spent flower stems can be removed at the base after blooming.

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.
