When to prune mangrove date palm 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 mangrove date palm
Cut dead fronds at the base near the trunk using clean, sterilised tools. Remove unwanted basal suckers with a sharp spade or saw at ground level to manage clump size.
Mangrove Date Palm is a clustering species that needs little pruning. Remove dead fronds and old fruiting stalks periodically. Unwanted suckers from the base can be cut away at ground level to control spread if the clump becomes too large. Do not remove green fronds — it has no benefit and harms the plant.

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.
