When to prune achimenes erecta 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 erecta
Pinch stem tips in spring when young to encourage branching. In autumn, once foliage yellows, cut all stems to soil level and store rhizomes cool and dry through dormancy.
Achimenes erecta dies back to dormant rhizomes each autumn — allow the stems and foliage to yellow and die naturally before cutting away dead top-growth. In spring, pinch growing tips once or twice to encourage bushy, upright growth and more flowering stems. Deadhead spent blooms through the season to keep the plant tidy.

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.
