When to prune mexican pinyon 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 mexican pinyon
Use clean, sharp tools to remove dead or problem branches at the collar. On young trees, candles can be pinched by half while still soft and green in spring to slightly compact growth. Never shear or cut into woody, needle-free stems.
Mexican Pinyon is a slow-growing, naturally well-formed pine that requires very little pruning. It shapes itself into a rounded form without intervention. Remove dead, diseased, or damaged branches as needed. Avoid heavy structural pruning — cutting back into old wood produces bare, dead stubs since pines cannot bud from leafless wood.

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.
