When to prune chiric sanango 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.
How to prune chiric sanango
Lightly trim back flowered stems to a healthy node. Remove dead, diseased, or crossing wood to open up the crown. Avoid cutting into very old, woody stems unless rejuvenation is the goal, as recovery is slower than in Brunfelsia pauciflora.
Chiric Sanango (Brunfelsia grandiflora) is a moderately vigorous tropical shrub that benefits from light annual pruning to maintain shape and encourage flowering. Like other brunfelsias, it responds well to cuts taken after flowering, which promote fresh branching and more blooming points. Heavy pruning is rarely needed given its naturally branched crown.

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.
