When to prune dwarf sugar palm in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune dwarf sugar palm
Cut dead fronds close to the cane using a sterilised saw or loppers. Remove spent, dead canes at soil level once flowering is complete and the cane has died back. New suckers from the base will replace them.
Dwarf Sugar Palm (Arenga engleri) is a suckering, clumping palm needing only light maintenance pruning. Remove dead or fully browned fronds at the trunk. Old canes that have flowered and died can be cut to the base — Arenga stems are monocarpic individually, but the clump persists via new offshoots. Do not cut live growing tips.

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.
