When to prune voodoo lily 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 voodoo lily
Pull or cut the collapsed spathe stalk cleanly from the corm. Do not cut the leaf while green — it photosynthesises for the corm all summer. In autumn, once fully yellowed, cut to the base.
Voodoo lily (Sauromatum venosum) needs almost no pruning. The flower spathe appears before leaves on a bare corm and collapses on its own; remove it at the base once it dies. Let the single leaf die back naturally in autumn, then cut the stem to the ground before dormancy.

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.
