When to prune slender-lined 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 slender-lined living stones
Allow the old leaf pair to collapse and dry on its own. Remove only when leaves have become a completely dry husk that falls away without force.
Slender-lined Living Stones (Lithops gracilidelineata) need no pruning. The annual leaf-pair renewal is entirely self-managed — old leaves dry up and split open to reveal new growth within. Removing leaves before they are fully desiccated interrupts nutrient transfer and can expose the plant to rot. No pruning tools are required for this species.

Pruning slender-lined living stones in the UK — FAQ
When should I prune slender-lined living stones in the UK?
Prune slender-lined living stones in spring, once growth resumes. 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.
Is it illegal to prune slender-lined living stones in spring or summer in the UK?

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.
