When to prune nicotiana × sanderae 'starmaker lime' 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 nicotiana × sanderae 'starmaker lime'
Remove spent flower clusters at their stem base. For late-season tidying, shear the plant lightly — removing up to one-quarter of the growth — then water and feed lightly to encourage fresh flowering shoots before the end of the season.
This compact hybrid Nicotiana blooms prolifically and maintains its shape well. Deadheading spent flower clusters keeps new buds coming. Plants can become a little leggy by late summer — trim back by one-quarter to restore bushiness and prompt a final flush before frost. Pruning needs are light compared to many annuals.

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.
