When to prune northsky blueberry in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune northsky blueberry
Remove 1–2 of the oldest canes (thick, dark, low-vigor) at ground level. Snip out any deadwood and thin overcrowded twiggy growth from the centre. On plants in their first 3 years, pinch off flower buds to build root and cane structure before allowing a full crop.
Yes — Northsky is a compact half-high hybrid blueberry suited to cold climates. It needs modest annual pruning once mature (after year 3). Remove the oldest, least productive canes to ground level each year and clear any deadwood. Its naturally low, dense habit means light annual maintenance keeps it fruiting well without the heavier pruning larger highbush types need.

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.
