When to prune dracontium polyphyllum in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune dracontium polyphyllum
Allow the petiole to yellow fully before cutting it at the base — premature removal reduces energy return to the corm. Wear gloves as the sap can cause skin irritation.
Dracontium polyphyllum is a geophytic aroid that typically produces a single compound leaf per season from its corm. There is almost nothing to prune — simply remove the leaf stalk once it yellows and dies back in late season. No structural pruning is possible or needed.

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.
