When to prune china girl dogwood 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 china girl dogwood
Use sharp, clean tools to remove dead or rubbing branches back to the branch collar. On young trees, select three to five well-spaced scaffold branches and remove competing leaders. Avoid topping — it destroys the natural form and invites disease.
China Girl dogwood (Cornus kousa) is a flowering tree that needs minimal pruning. Its branching is naturally attractive and layered. Remove dead, damaged, or crossing limbs while the tree is young to establish structure. Mature trees need only occasional crown cleaning — heavy pruning is harmful and rarely warranted.

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.
