When to prune creeping rosemary 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 creeping rosemary
Shorten wayward stems by cutting back to a leafy shoot junction. Do not shear it flat — work stem by stem, never cutting below the lowest leaves.
Creeping rosemary (Prostratus) is a low-spreading ground cover that needs very little pruning. After flowering, lightly trim any stems that are heading in an unwanted direction or that look straggly. Avoid hard pruning into bare wood — it rarely breaks back from leafless stems. Light shaping once a year is sufficient for most gardens.

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.
