When to prune hairy jovibarba 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 hairy jovibarba
Twist or cut away the dead flowering rosette at its base. Remove dried outer leaves by pulling gently downward. Leave healthy offsets in place or separate them for propagation.
Hairy Jovibarba rarely needs pruning. Remove dead or dried outer leaves and spent flower stalks after blooming — the rosette that flowers will die naturally (monocarpic), leaving offsets behind. Simply detach dead rosettes and tidy up offsets as needed. No shaping or cutting required.

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.
