When to prune rollers houseleek in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune rollers houseleek
Twist or cut out the spent flowering rosette at soil level, leaving surrounding offsets intact. Remove any dried or mushy individual leaves by gently pulling them away from the base.
Roller's Houseleek (Sempervivum globiferum) is a monocarpic rosette succulent — individual rosettes die after flowering, which is normal. No pruning is needed to shape the plant. Simply remove spent flowering rosettes and any dead or withered offsets (chicks) as they appear. The surrounding chicks fill in naturally without any cutting.

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.
