When to prune luisier's lavender 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 luisier's lavender
Pinch or snip stems just above a pair of leaves to encourage branching.
Luisier's Lavender responds well to regular light pruning. Pinching back the growing tips every couple of weeks keeps the plant bushy, delays flowering (which can turn the leaves bitter), and gives you a steady harvest. Always cut just above a leaf node.

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.
