When to prune olive 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 olive living stones
Do not prune at any stage of the renewal cycle. Remove old leaf remnants only when they are completely dry and papery and separate without any pulling force.
Olive Living Stones (Lithops olivacea) need no pruning. The annual replacement of the leaf pair is entirely self-directed — old leaves dry and split open as new ones grow through the fissure. Intervening with scissors or fingers at any point in this cycle risks damaging the delicate new growth and introducing fungal issues.

Pruning olive living stones in the UK — FAQ
When should I prune olive living stones in the UK?
Prune olive living stones in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

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.
