When to prune achimenes 'peach blossom' 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 achimenes 'peach blossom'
Pinch growing tips in spring to encourage bushiness. In autumn, let foliage die back naturally before cutting dead stems to soil level and storing rhizomes cool and dry.
Achimenes 'Peach Blossom' dies back to dormancy each autumn — allow stems to yellow and die naturally, then cut away dead growth before storing rhizomes dry. In spring, pinch growing tips once or twice to encourage branching and a fuller flush of blooms. No pruning is needed mid-season unless removing dead flowers.

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.
