When to prune raspberry 'autumn bliss' 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 raspberry 'autumn bliss'
Cut all canes flush to the ground with loppers or sharp secateurs. Remove and dispose of old material. In spring, thin emerging new canes to about 10 cm (4 in) apart, leaving the strongest to grow on. Tie canes to wires or supports as they reach 60–90 cm tall.
Autumn Bliss is an autumn-fruiting primocane raspberry, pruned identically to Heritage: cut all canes to ground level in late winter after fruiting. This regime could not be simpler. Fresh canes grow each spring and bear fruit from August through October. No need to distinguish old from new canes — cut everything down.

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.
