When to prune cornelian cherry 'jolico' 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 cornelian cherry 'jolico'
Remove dead, diseased, and crossing branches cleanly. Thin the canopy lightly every few years to improve light and air flow. If grown as a tree, gradually lift the crown by removing lower sideshoots over several years.
Cornelian Cherry 'Jolico' is a heavy-cropping large-fruited cultivar of Cornus mas, grown as a large shrub or small tree. It requires minimal regular pruning — mainly removing dead or crossing wood and occasional thinning to allow light into the canopy. Flowers appear on bare wood in late winter, so prune after.

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.
