When to prune lithops 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
Do nothing. Once the old leaf pair is fully papery and dry you can gently peel the husk away, but intervening early damages the new growth. Never cut green or partially dried leaves.
Lithops (living stones) require no pruning at all. The plant sheds its old pair of leaves annually as a natural process — the old leaves dry and split to reveal the new pair growing inside. Do not cut or remove the old leaves; let them wither completely on their own so the new body can absorb their moisture.

When should I prune lithops in the UK?
Prune lithops in early to mid spring. 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.
Is it illegal to prune lithops in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to lithops, since birds do not nest in it. The Wildlife and Countryside Act 1981 still protects any active nest you do find anywhere in the garden — the rule is about the nest, not the plant.
How do you prune lithops?

How often does lithops need pruning in a British garden?
Never — this is a self-renewing plant with no pruning requirement. Lithops (living stones) require no pruning at all. The plant sheds its old pair of leaves annually as a natural process — the old leaves dry and split to reveal the new pair growing inside. Do not cut or remove the old leaves; let them wither completely on their own so the new body can absorb their moisture.
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.
