When to prune alternanthera reineckii 'mini' 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 alternanthera reineckii 'mini'
Use fine-tipped aquascaping scissors to cut stems just above a node. Replant trimmed tips directly into the substrate to propagate and fill in sparse areas.
Alternanthera reineckii 'Mini' is a compact aquarium foreground plant that benefits from regular trimming to encourage dense, bushy growth and maintain its low profile. Without trimming it will stretch toward light and lose its compact form. Replant tip cuttings after each trim to fill gaps.

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.
