When to prune silver crown cotyledon 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.

Silver Crown Cotyledon is a shrubby succulent that responds well to light pruning to maintain shape and prevent legginess. Pinch or cut back elongated stems after flowering to keep growth compact. Remove spent flower stalks at the base. This is one of the more pruning-receptive succulents — occasional shaping keeps it attractive.

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.
