When to prune jasminum sambac 'grand duke of tuscany' in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune jasminum sambac 'grand duke of tuscany'
Cut flowered shoots back by one-quarter after blooming, to a strong outward-facing node. Remove any dead or very woody base stems to maintain vigour without over-pruning.
Jasminum sambac 'Grand Duke of Tuscany' is a slower-growing, more upright form that still benefits from post-bloom pruning. Trim stems back after each flower flush to stimulate new growth that will carry more buds. Remove congested or dead stems at the base. This cultivar is less rampant, so pruning can be lighter.

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.
