When to prune alphonso mango in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune alphonso mango
After picking fruit, cut back new vegetative shoots to 20–30 cm from the main framework branches. Remove crossing, dead, and downward-growing branches. On overgrown trees, de-horn (hard prune) no more than one-third of the canopy per year to avoid excessive stress. Apply wound sealant in humid climates.
Alphonso Mango benefits from pruning after harvest to control tree size, open the canopy for light and airflow, and stimulate the flush of new growth on which the next season's flowers form. Without pruning, trees become too tall to harvest easily and yields decline. Annual post-harvest pruning is standard practice.

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.
