When to prune bob gordon elderberry 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 bob gordon elderberry
Cut oldest (darkest-barked, three-year-plus) canes to the ground each year. Select eight to twelve healthy one- and two-year-old canes to retain, spacing them evenly. Remove any winter-damaged tips to healthy wood and eliminate suckers that spread beyond the desired clump footprint.
Bob Gordon Elderberry is a productive fruiting shrub that benefits from regular renewal pruning. It fruits best on one- and two-year-old canes. Each year, remove the oldest canes (three years and older) at ground level and thin the total cane count to eight to twelve. This keeps the shrub vigorous and maximises the large, heavy flower clusters this variety is known for.

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.
