When to prune mexican blue 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 mexican blue palm
Use a sharp saw or heavy loppers to cut dead fronds close to the trunk. For fruiting stalks, cut at the point of origin from the crownshaft.
Mexican Blue Palm is slow-growing and needs very little pruning. Remove only fully dead fronds and old flower or fruit stalks. Dead fronds on young specimens may naturally persist for years — this is normal and protective. Never remove green or silvery-blue fronds, as this weakens the palm significantly.

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.
