When to prune chandler blueberry 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 chandler blueberry
Start by removing dead or damaged wood. Then cut out the oldest, most unproductive canes (thick, grey bark) at ground level, leaving 6–8 healthy canes. Tip back remaining canes by 20–25% to reduce crop load and increase berry size. Open up the centre for airflow.
Chandler blueberry, like all highbush cultivars, requires structured annual pruning to maintain fruiting productivity. Prune in late winter while dormant. Remove dead, damaged, and crossing canes. Cut out canes older than 5–6 years at the base, keeping 6–8 vigorous canes of mixed ages. Tip back long canes to encourage well-spaced lateral buds and larger berries.

Pruning chandler blueberry in the UK — FAQ
When should I prune chandler blueberry in the UK?
Prune chandler blueberry 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 chandler blueberry 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 chandler blueberry for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
