When to prune golden mosaic ctenanthe 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 golden mosaic ctenanthe
Cut individual leaf stems at the base with clean scissors. Remove any all-green reverted stems entirely at soil level. Divide congested root clumps in spring, separating rooted stems.
Golden Mosaic Ctenanthe needs minimal pruning. Remove yellowed, damaged, or tatty leaves by cutting the entire petiole cleanly at the base. If stems become crowded or the plant produces unvariegated growth (reversion), remove those stems entirely. Dividing congested clumps every 2–3 years is more beneficial than pruning.

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.
