When to prune ludwigia palustris 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 ludwigia palustris
Trim just above a node with clean scissors. Replant the cut tops as cuttings; they root readily in substrate or even floating briefly.
Ludwigia palustris is a versatile stem plant used in aquariums and paludariums. It grows steadily and benefits from routine trimming to stay compact and branched. Cut stems above a node and replant tops as cuttings. Remove any decaying lower leaves to prevent water quality issues. Growth rate varies with light and nutrients.

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.
