When to prune ctenanthe oppenheimiana 'tricolor' 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 ctenanthe oppenheimiana 'tricolor'
Use clean, sharp scissors to cut spent or damaged leaf stems at soil level. This encourages the plant to push energy into new foliage rather than maintaining dying growth.
Ctenanthe oppenheimiana 'Tricolor' requires only light maintenance pruning. Remove dead, yellowed, or damaged leaves by cutting at the base of the leaf stem. Older outer leaves naturally die back as new growth emerges from the centre. No shaping or structural pruning is needed for this clumping houseplant.

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.
