When to prune bloodleaf plant in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune bloodleaf plant
Pinch soft shoot tips just above a leaf node to encourage branching and maintain compact growth. For overgrown plants, cut all stems back by one-half to two-thirds in early spring before new growth begins.
Bloodleaf (Iresine herbstii) grows quickly and benefits from regular pinching to maintain a dense, bushy habit. Without it, stems become long and sparsely leaved. Pinch stem tips frequently through the growing season. Cut the plant back hard in late winter or early spring if it becomes woody or sprawling.

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.
