When to prune dwarf windmill 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 dwarf windmill palm
Cut dead fronds cleanly at the petiole base with loppers or a pruning saw. Do not strip the fibrous trunk material; it is protective and natural.
Dwarf Windmill Palm (Trachycarpus wagnerianus) has the same minimal pruning needs as its close relative T. fortunei. Remove fully dead fronds and old fruiting stalks only. Keep all green fronds intact — they supply the energy this slow-growing palm needs. Rarely needs more than a quick annual tidy.

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.
