When to prune common 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 common dogwood
Cut all or most stems to within 15–30 cm of the ground every one to two years for the best stem colour. For a more natural hedge or wildlife planting, remove only one-third of the oldest stems per year. Remove suckers outside the desired footprint as they appear.
Common dogwood (Cornus sanguinea) is a vigorous, suckering native shrub prized for autumn berry, leaf colour, and winter stem colour. Coppice or stool it in late winter to keep stems young and colourful. Without pruning it becomes a large, untidy thicket — regular hard cutting keeps it productive and ornamental.

Pruning common dogwood in the UK — FAQ
When should I prune common dogwood in the UK?
Prune common dogwood in early to mid spring. 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.
Is it illegal to prune common dogwood in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check common dogwood for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.
How do you prune common dogwood?

How often does common dogwood need pruning in a British garden?
Annually to every 2 years (coppice); or rolling one-third renewal annually.

Coppice or stool it in late winter to keep stems young and colourful. Without pruning it becomes a large, untidy thicket — regular hard cutting keeps it productive and ornamental.
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.
