When to prune chokeberry 'viking' 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 chokeberry 'viking'
Remove dead or inward-crossing stems at the base each year. Every 3–4 years, cut the oldest one-third of stems to ground level to rejuvenate fruiting wood. Avoid shearing, which destroys the natural vase form and removes fruiting laterals.
Chokeberry 'Viking' is a compact, upright cultivar of Aronia melanocarpa that needs minimal pruning. It naturally maintains a tidy form and fruits heavily on established wood. Remove dead or damaged stems each late winter. Every few years, thin out the oldest, most congested stems at the base to admit light and stimulate a flush of productive new growth.

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.
