When to prune astilbe 'bridal veil' 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 astilbe 'bridal veil'
Snip spent flower plumes back to the base of the stem after blooming. In autumn or early spring, cut the entire plant to ground level with clean shears before new growth emerges.
Astilbe 'Bridal Veil' requires minimal pruning. Deadhead the white flower plumes after they fade if you want a neat appearance, or leave them standing for winter texture. Cut all stems to ground level in late autumn or early spring before new growth begins. Division every 3–4 years maintains plant health.

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.
