When to prune creeping lemon thyme 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 lemon thyme
Using scissors or small secateurs, trim flowered stems back by roughly half, cutting just above a visible set of leaves. Do not cut into the hard woody base — thyme rarely regenerates from bare old wood.
Creeping Lemon Thyme benefits from trimming after flowering to keep it compact and prevent it becoming straggly. Cut back the flowered stems by about half once blooms fade in summer. An optional light tidy in early spring removes any winter-killed tips. Avoid cutting into old, woody, leafless stems.

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.
