When to prune grapeleaf abutilon in the UK
Why the timing differs here

How to prune grapeleaf abutilon
Deadhead spent blooms; cut back leggy stems to a healthy bud or node.

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.
