When to prune keitt 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 keitt mango
Remove current-season growth back to 20–30 cm stubs from framework branches. Eliminate dead, crossing, and downward-angled wood. Keitt trees can be kept at 8–10 ft for backyard management with consistent annual heading cuts. Apply wound sealant if working in humid, anthracnose-prone climates.
Keitt Mango is a late-season, low-fibre cultivar that grows vigorously and benefits from post-harvest pruning to control size and refresh fruiting wood. Keitt often produces a second flush of fruit, so time pruning carefully after the final pick. Pruning opens the canopy, reduces fungal disease, and sets up the tree for the following year.

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.
