When to prune echinodorus uruguayensis 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 echinodorus uruguayensis
Cut old outer leaves at the base of the petiole with long-bladed aquatic scissors. Work from the outside of the rosette inward, leaving all healthy central growth untouched.
Echinodorus uruguayensis is a large, robust Amazon sword relative that benefits from regular removal of old, damaged, or yellowing outer leaves to keep the plant healthy and water quality stable. New leaves continuously emerge from the center. In smaller aquariums, trim the tallest leaves periodically to manage its considerable size.

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.
