When to prune california fan 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 california fan palm
Remove dead fronds and fruiting stalks by cutting at the trunk with a pole saw or hire a certified arborist for tall specimens. Leave small petiole stubs to avoid trunk injury.
California Fan Palm naturally forms a dead-frond skirt that provides wildlife habitat — many conservation guidelines recommend leaving it. For managed landscapes, prune the skirt annually for fire safety or aesthetics. Remove only dead fronds and old fruit stalks; never cut green fronds. Mature trees require an arborist due to height.

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.
