When to prune nematanthus 'cheerio' 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 nematanthus 'cheerio'
Pinch out stem tips with your fingers or snip with clean scissors to encourage branching. After flowering, cut longer stems back by one-third, cutting just above a leaf node.
Nematanthus 'Cheerio' (goldfish plant) benefits from a light pinch and trim after flowering to keep growth compact and encourage branching. Without it, stems become long and bare. Pinch out growing tips during the growing season to promote bushiness, and cut back longer stems by one-third after the main bloom period.

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.
