When to prune sedum clavatum 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 sedum clavatum
Pull dead lower leaves cleanly from the stem. Cut spent flower stalks at the base. For leggy growth, trim stems back to a compact rosette, allow cuts to callous, then re-root in gritty, well-drained compost.
Sedum clavatum is a small rosette-forming succulent needing minimal pruning. Remove dead outer leaves and snip spent flower stalks at their base after the spring bloom. If stems become leggy in low light, trim back to a healthy rosette and re-root the cuttings. No regular pruning schedule is 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.
