When to prune golden sedum 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 golden sedum
Pinch stem tips just above a leaf node using clean fingers or scissors to promote branching. Cut back leggy stems by up to one-third. Remove dead leaves at the base by pulling gently downward. Cuttings callous in a day or two before potting.
Golden Sedum is a low-growing succulent that needs minimal pruning. Pinch or trim leggy stems in spring to encourage compact, bushy growth — plants can become straggly in low light. Remove dead or frost-damaged leaves at any time. Trimmings root easily, so save them for propagation.

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.
