When to prune white stonecrop in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune white stonecrop
Snip dead or damaged stems back to healthy tissue at the base. Remove spent flower stalks cleanly at the stem junction. A light shear across the whole mat can refresh leggy patches.
White Stonecrop is a self-sufficient low groundcover that rarely needs pruning. Remove dead stems and any frost-damaged growth in early spring. Deadhead spent flower stalks after the early-summer bloom to keep the plant tidy and discourage excessive self-seeding. No shaping or hard pruning is required under normal conditions.

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.
