When to prune english lavender 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 english lavender
Cut the entire plant back to a rounded mound shape, removing all spent flower stalks and trimming into the soft leafy growth — but stop before bare woody stems. Use shears for speed.
English lavender (Hidcote) must be pruned annually to stay compact and avoid becoming a woody, open mound. Cut back immediately after flowering, removing spent stalks and trimming the foliage mound to a neat dome — removing about one-third of growth. Do not cut into bare old wood. A second light tidy in early spring is optional.

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.
