When to prune loch ness blackberry 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 loch ness blackberry

Loch Ness is a floricane blackberry — canes fruit in their second year, so you prune out fruited canes after harvest and train new ones for next year. Annual post-harvest pruning is critical for productivity and disease control. Without it the plant becomes a tangled, unproductive thicket very quickly.

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.
