When to prune mexican hat 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.

Mexican Hat Palm needs minimal pruning. Remove only fully brown or dead fronds by cutting cleanly at the base. Never remove green or yellowing fronds — this palm grows slowly and removing live fronds stresses the plant and slows growth. Cosmetic tidying is all that's needed.

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.
