When to prune bouquet dill 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 bouquet dill
Cut stems above a leaf node for ongoing foliage. To harvest seed heads, snip the whole umbel just before fully ripe and dry upside down in a paper bag.
Bouquet dill is grown both for leaves and its large flower heads. For leaf production, snip outer stems above a node every week or two and pinch any flower stalks early. If growing for seed or cut flowers, let it bolt freely. Once dill flowers, leaf quality declines sharply — timing your pruning to your goal matters.

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.
