When to prune açaí 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 açaí palm
Cut dead fronds close to the trunk with a sharp saw or loppers. Leave a short stub rather than cutting flush, which can damage the trunk. Do not remove yellow or partially green fronds.
Açaí palm is a clustering tropical palm that needs no traditional pruning. Remove only fully dead or severely damaged fronds by cutting cleanly at the base. Never cut green fronds — doing so stresses the palm and reduces fruit production. Let the clump develop naturally.

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.
