When to prune hardy kiwi in the UK
Why the timing differs here
This one bleeds sap heavily if cut in late winter or early spring, so the RHS advises pruning in late summer or early autumn instead — the opposite of the general dormant-season rule most pruning guides give.
How to prune hardy kiwi
Train one or two permanent main rods along wires. Each winter, cut back all laterals that fruited to 2–3 buds from the main rod. Remove entirely any shoots that have fruited for 3+ years. Tie in new extension growth during summer and pinch excess shoots to 5–6 leaves.
Hardy Kiwi is a vigorous deciduous climber that must be pruned hard each year or it rapidly becomes an unmanageable thicket. It fruits on short spurs from one-year-old laterals growing off a permanent framework. Establish a strong main rod and trained laterals, then prune yearly to renew fruiting spurs.

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.
