When to prune cotyledon papillaris 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 cotyledon papillaris
Use clean scissors to remove dead leaves and cut spent flower stems back to the main stem. Avoid removing healthy leaves as the plant stores water in them.
Cotyledon papillaris is a compact succulent that rarely needs pruning. Remove any dead or damaged leaves cleanly from the base. Spent flower stalks should be cut back to the stem after blooming. Beyond that, this small species maintains its natural form without intervention and does not benefit from heavy 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.
