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 san jose hesper palm

Cut dead fronds at the petiole base with loppers. Persistent petiole stubs on the trunk can be carefully removed flush with the trunk on mature specimens for aesthetics. Do not wound the trunk tissue beneath. Wear gloves as the leaf margins can be sharp.

San Jose Hesper Palm needs only dead-frond removal. This drought-adapted Baja California palm is slow-growing and virtually self-maintaining in the right climate. Remove only fully brown fronds, cutting at the petiole base. Never cut the central growing spear. Old petiole bases persist on the trunk for years — leave them unless posing a safety hazard on a mature landscape tree.

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.
