When to prune american persimmon 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 american persimmon
On young trees, select 3–4 well-spaced scaffold branches and remove competing leaders. On established trees, thin crowded or inward-facing branches to improve light penetration; make clean cuts just outside the branch collar.
American Persimmon needs pruning mainly in its early years to establish a strong open-center or central-leader framework. Mature trees need only light corrective pruning — remove crossing, dead, or diseased branches. Avoid heavy pruning on mature trees as it reduces fruit set and can stimulate unproductive vegetative growth.

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.
