When to prune dorothy's 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 dorothy's living stones
Allow old leaves to shrivel and dry completely without intervention. Remove only fully mummified husks that have dried to a papery shell and detach without resistance.
Dorothy's Living Stones (Lithops dorotheae) require no pruning. The plant naturally sheds its old leaf pair each year as new leaves push through from the center. Interfering with this process by removing leaves early stresses the plant and interrupts nutrient recycling from the old pair into the new. Leave it completely alone.

Pruning dorothy's living stones in the UK — FAQ
When should I prune dorothy's living stones in the UK?
Prune dorothy's 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.
