When to prune dittany of crete 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 dittany of crete
Use fine scissors to snip off spent flower stems at their base after blooming. In early spring, remove any dead or winter-damaged stems, cutting back to the first sign of green growth. Avoid hard pruning into old bare wood, which this plant regenerates from poorly.
Dittany of Crete is a low, softly woolly herb that benefits from light pruning after flowering to stay neat and encourage fresh aromatic growth. It is not aggressive, so heavy pruning is unnecessary. Trim spent flower stems and any straggly growth after the summer bloom. Remove dead growth in early spring.

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.
