When to prune cornus kousa 'miss satomi' 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 cornus kousa 'miss satomi'
Thin out crossing or rubbing branches back to a healthy lateral, maintaining the natural horizontal layers. Never cut the central leader unless damaged.
Cornus kousa 'Miss Satomi' has a naturally elegant, tiered horizontal branching habit that should not be corrected. Pruning is rarely needed. Remove dead, crossing, or damaged branches to preserve the open canopy and showcase the pink bracts. Avoid heavy pruning, which disrupts the distinctive layered form.

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.
