When to prune thatch 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 thatch palm
Cut dead fronds close to the trunk with clean, sharp loppers or a pruning saw. Remove old flower/fruit stalks at their attachment point.
Thatch Palm (Thrinax radiata) needs very minimal pruning. Remove only fully dead, brown fronds at the base. This slow-growing palm is sensitive to over-pruning, which can weaken it substantially. Never remove green fronds. In a tidy landscape setting, remove dried flower or fruit stalks as desired.

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.
