When to prune achimenes 'tarantella' 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 'tarantella'
Pinch stem tips in spring to promote branching. Once foliage yellows in autumn, cut dead stems to soil level. Store rhizomes in barely moist compost or dry, frost-free conditions over winter.
Achimenes 'Tarantella' is a seasonal grower that goes dormant each autumn. Allow foliage to die back naturally, then remove dead top-growth and store rhizomes dry for winter. In spring, pinch growing tips once or twice to build a bushy, branching habit and maximise the flower display. Deadhead to keep plants tidy in season.

Is it illegal to prune achimenes 'tarantella' in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is.

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.
