When to prune crabapple 'hanagasa' 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 crabapple 'hanagasa'
Remove water sprouts, suckers, and inward-growing branches first, then thin crossing limbs to open the canopy. Never remove more than one-third of total foliage in a season. Sterilise tools between cuts to reduce fire blight risk.
Yes, Crabapple 'Hanagasa' needs annual pruning to maintain its flowering form, control size, and prevent fungal disease. Prune to remove water sprouts, crossing branches, and dead wood, and to open the canopy for airflow. Hanagasa blooms on previous year's wood, so timing is critical — prune too late and you sacrifice next season's flowers.

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.
