When to prune preston 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 preston palm
Sever dead fronds close to the trunk using clean, sharp secateurs or a pruning saw. Sterilise tools between plants to prevent disease spread.
Preston Palm needs minimal intervention. Remove dead or fully browned fronds at the base when they appear, and do nothing else. Do not cut green fronds to make the palm look tidier — palms are not shrubs and cannot be shaped without harm. Let the natural crown form develop undisturbed.

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.
