When to prune king anthurium 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 king anthurium
Cut the petiole of a dead or yellowed leaf cleanly at its base with sterilized scissors. Remove faded flower spathes at their stem. Do not cut into the main crown or growing tip.
King Anthurium needs only cosmetic pruning. Remove old, yellowed, or damaged leaves by cutting the petiole cleanly near the base. Spent spathes and spadices can be snipped off once they fade. No structural pruning is needed or recommended — the plant grows a single upright stem and pruning it would cause serious damage.

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.
