When to prune nemesia 'sunsatia cranberry' 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 nemesia 'sunsatia cranberry'
Cut stems back by half with sharp scissors, always just above a leaf node. Remove yellowing or dead stems at the base and deadhead spent flowers in between.
Nemesia 'Sunsatia Cranberry' is bred for improved heat tolerance but still benefits from cutting back by half when flowering slows midsummer. This stimulates fresh branching and a reliable second flush. Regular deadheading between hard cuts keeps the plant tidy and directs energy into new blooms rather than seed set.

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.
