When to prune echinodorus 'red flame' 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 'red flame'
Use sharp aquatic scissors to cut old or dying leaves at the base of the petiole. Allow daughter plantlets on flower stalks to develop roots and several leaves before detaching.
Echinodorus 'Red Flame' requires routine removal of older outer leaves as the plant continuously produces new growth from its center. This keeps the plant tidy and prevents decomposing matter from degrading water quality. Flower stalks can be cut at the base or kept to develop adventitious plantlets for propagation.

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.
