When to prune anchomanes difformis 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 anchomanes difformis
Cut the spent petiole cleanly at ground level once completely dead and brown. Wear gloves — the sap contains irritating calcium oxalate. Clear mulch and debris before new growth emerges.
Anchomanes difformis is a dramatic West African tuberous aroid that dies back to its corm after each growing season. It needs no pruning while in growth. Once the single large leaf dies back naturally, remove the dead petiole at the base. No shaping or cutting of live growth is appropriate.

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.
