When to prune meadowsweet 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 meadowsweet
Cut spent flower stems back to just above a healthy leaf node to encourage further growth. In autumn, remove all top growth to 10 cm above the ground using shears or secateurs.
Meadowsweet benefits from deadheading to prolong flowering and prevent excessive self-seeding. After the main bloom in midsummer, cut stems back by a third to encourage a secondary flush of growth. In late autumn, cut the whole plant back to the basal leaves. Divide congested clumps every three to four years.

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.
