When to prune rotala indica 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 indica
Cut stems above a node with sharp scissors. Replant trimmed tops as new cuttings; remove and discard bare lower sections.
Rotala indica is a compact aquarium stem plant suited to midground planting. It grows steadily and benefits from periodic trimming to remain dense and well-branched. Cut above a node and replant the tops to increase planting density. Remove deteriorating lower leaves to prevent fouling the substrate and reduce algae risk.

Pruning rotala indica in the UK — FAQ
When should I prune rotala indica in the UK?

How often does rotala indica need pruning in a British garden?
Every 3–5 weeks. Rotala indica is a compact aquarium stem plant suited to midground planting. It grows steadily and benefits from periodic trimming to remain dense and well-branched.

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.
