When to prune broadleaf stonecrop 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 broadleaf stonecrop
Use clean scissors to cut back untidy or damaged stems to a healthy rosette or node. For ground-cover plants, a light shear with garden scissors after flowering will prompt fresh growth. Avoid cutting into the woody crown.
Broadleaf Stonecrop is a low, mat-forming succulent that rarely needs pruning. Trim back any straggly or frost-damaged stems in early spring to tidy the plant and encourage fresh rosette growth from the base. In containers it stays naturally compact; outdoor ground-cover plants can be sheared lightly after flowering.

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.
