When to prune sempervivum 'reinhard' 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 sempervivum 'reinhard'
Twist out dead flowering rosettes at the base and remove papery outer leaves by hand. Use clean scissors to sever stolons if you want to separate or thin offsets.
Sempervivum 'Reinhard' requires very little pruning. Peel away dried or dead outer leaves and remove spent monocarpic rosettes after they flower and die. Offsets fill in naturally. No cutting or shaping is necessary — intervene only to keep the plant tidy and well-ventilated.

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.
