When to prune flame seedless grape 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 flame seedless grape
For cane pruning: each winter select 1–2 strong canes from the head of the vine, tie them horizontally to wires, and cut all others to 1–2 bud renewal spurs. For spur pruning: cut all lateral shoots back to 2-bud spurs on a permanent cordon. Either way, remove the bulk of prior-year wood.
Flame Seedless Grape needs firm annual pruning to maintain vigour and fruit quality. Prune in late winter during dormancy using either cane pruning (replacing the entire fruiting cane each year) or spur pruning (cutting laterals to 2 buds). Flame Seedless performs well with cane pruning. Remove 80–90% of last year's growth each season.

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.
