When to prune pawpaw 'shenandoah' in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune pawpaw 'shenandoah'
Select 3–5 strong scaffold branches in the first 2–3 years and remove competing upright shoots. Annually thin crossing or crowded branches. Cut suckers from the base at ground level throughout the growing season.
Pawpaw 'Shenandoah' is a deciduous understory tree that needs modest formative pruning when young to establish a strong scaffold. Mature trees need only light annual thinning to maintain airflow and light penetration. Remove suckers regularly — pawpaws sucker freely and will form a thicket if unmanaged.

Is it illegal to prune pawpaw 'shenandoah' in spring or summer in the UK?
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.
