When to prune goldfish plant 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 goldfish plant
Pinch growing tips between fingers or use clean scissors to cut stems back by one-quarter to one-third after flowers fade, cutting just above a leaf node. Remove any bare or dead stems at the base entirely. Avoid cutting into old woody stems with no leaves.
Goldfish plants bloom on new growth, so pruning is genuinely useful. Pinch or trim back stems after each flowering period to encourage bushy new growth and more flower buds. Without occasional trimming, plants become straggly and bloom less. A light post-bloom cut keeps the plant compact and prolific.

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.
