When to prune graptopetalum amethystinum 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 graptopetalum amethystinum
Strip or snip dried lower leaves from the stem. Cut spent flower stalks at the base. For leggy stems, cut back to a leaf node and allow the cut end to callous before re-rooting.
Graptopetalum amethystinum (lavender pebbles) is a slow-growing succulent needing very little pruning. Remove dead lower leaves as the stem elongates and cut spent flower stalks after spring blooming. If stems become leggy, you can trim them back and re-root the cuttings, but this is propagation rather than routine maintenance.

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.
