When to prune rotala macrandra 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 rotala macrandra
Snip each stem cleanly above a node with fine aquascaping scissors. Replant trimmed tops into the substrate; remove bare lower sections entirely.
Rotala macrandra is a delicate, high-light aquarium stem plant requiring routine trimming to keep growth dense and the vivid red coloration at its best. Stems become leggy without regular cutting. Trim above a node, replant tops as cuttings. Remove yellowing or deteriorating lower leaves to prevent nutrient issues in the tank.

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.
