When to prune tufted thyme 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 tufted thyme
Use fine scissors to lightly shear the mound after flowering, removing just the spent flower heads and softening any irregular edges. Avoid cutting into the tight, woody basal stems.
Tufted thyme (Thymus caespititius) forms a low, tight mound and is among the least demanding thymes to maintain. A light trim after flowering in summer removes spent blooms and keeps the cushion dense. It is naturally compact and slow-growing, so heavy pruning is rarely needed. Remove dead material in spring to expose new growth.

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.
