When to prune satsuma mandarin 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 satsuma mandarin
Use sharp, sterile secateurs. Thin out crowded interior branches to improve light penetration, shorten any excessively long shoots to an outward lateral, and remove dead wood. Avoid hard heading cuts on productive spur wood.
Satsuma Mandarin requires only light pruning. It bears fruit on short spurs and naturally forms a compact, spreading shape. Remove dead or diseased branches, any crossing limbs that rub, and occasional water sprouts. Heavy pruning reduces fruit the following season, so a gentle hand is essential.

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.
