When to prune chinese broccoli 'kailaan green' in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.

Cut the central stem with a sharp knife about 15–20 cm down, just above a leaf node. This triggers lateral shoots, which are harvested in the same way over the following weeks. Remove yellowed leaves at any time.
Chinese Broccoli 'Kailaan Green' is harvested by cutting the central flowering shoot before flowers fully open, then allowing side shoots to develop for follow-on harvests.

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.
