UK pruning guide · RHS timing
When to prune rivieri 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 rivieri voodoo lily
Use a sterile sharp blade to cut spent flower stalks at ground level promptly after the bloom fades to redirect energy to the corm. Remove dead leaf stalks the same way in autumn.
Rivieri Voodoo Lily (Devil's Tongue) is a deciduous tropical that produces a single leaf per season and goes dormant each year. No pruning is required. Cut the spent inflorescence stalk at the base after the flower fades, and remove the dead leaf stalk in autumn once it collapses.

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.
