When to prune mulberry 'shangri-la' 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 mulberry 'shangri-la'
Train to an open-center or modified central-leader form with 3–4 scaffold branches. Each winter, remove water sprouts from the base and main trunk, thin crossing branches, and shorten overly long shoots to maintain the compact form. Keep cuts small — Morus nigra is a slow healer.
Shangri-La Mulberry is a popular self-fertile, compact Morus nigra selection that fruits heavily and stays manageable in size. It benefits from open-center training when young. Established trees need only light annual pruning — remove dead wood, water sprouts, and any crossing branches. Prune strictly in dormancy to avoid excessive sap bleeding.

Is it illegal to prune mulberry 'shangri-la' in spring or summer in the UK?

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.
