When to prune hall's 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 hall's living stones
Do not prune. Only once the old pair is a fully dry, papery husk with no green or fleshy tissue remaining should you gently remove it — and only if it does not detach on its own.
Hall's Living Stones (Lithops hallii) need no pruning. This Lithops species, like all in the genus, renews itself annually by growing a new leaf pair from within the old one. The old leaves transfer moisture and nutrients to the new growth as they shrivel — cutting them away early deprives the plant of this resource.

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.
