When to prune fishtail 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 fishtail palm
Cut dead frond stems close to the cane using clean, sharp secateurs. When an entire cane dies after fruiting, cut it to the ground to encourage remaining or new canes. Never cut into the central growing crown of any living cane.
Fishtail palm is a clumping palm that needs only dead frond removal. Cut brown or dead fronds at the base near the trunk as they occur. Do not remove green fronds — fishtail palms are monocarpic per stem (each cane dies after fruiting), so preserving green fronds on remaining canes is essential to plant health.

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.
