When to prune chinese windmill palm 'bulgaria' 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 chinese windmill palm 'bulgaria'
Use a sharp pruning saw or heavy-duty bypass loppers to remove dead fronds close to the trunk. Leave dried leaf bases in place unless they are loose enough to pull away cleanly by hand.
Chinese Windmill Palm 'Bulgaria' needs only dead-frond removal. Cut fully brown fronds at the petiole base — the fibrous trunk is self-protecting but clean cuts reduce disease entry. Do not remove old leaf bases (boots) aggressively; they offer natural trunk insulation, which matters for this cold-hardy cultivar grown in cool climates.

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.
