When to prune american elderberry 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 american elderberry
Cut all canes older than 3 years to ground level. Keep 6–12 of the strongest 1- and 2-year canes per plant. Snip out any dead, diseased, or crossing stems with loppers or a pruning saw at the base.
American elderberry needs regular pruning to stay productive and manageable. It fruits on second-year canes, so remove all canes older than three years each late winter plus any dead or crossing stems. Hard rejuvenation every 4–5 years restores vigor. Without pruning, shrubs become dense and fruit quality declines.

Pruning itself is not illegal, but destroying an active nest is.

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.
