When to prune cascade hops 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 cascade hops
In late autumn, use loppers to cut all bines to 3–4 inches (8–10 cm) above ground. Come spring, let shoots emerge, then select the 2–3 strongest per hill and train them clockwise up strings or a trellis. Remove remaining shoots at soil level.
Cascade Hops require significant annual pruning — they are vigorous perennial climbers producing 20-foot bines each year. Cut all bines to the ground in late autumn once leaves drop. In spring, train only 2–3 strongest shoots per string; rub off the rest early. After harvest, cut all growth back to 3–4 inches above ground.

Pruning cascade hops in the UK — FAQ

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.
