When to prune zantedeschia jucunda 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 zantedeschia jucunda
Cut spent flower stems cleanly at the base with sharp, clean scissors or secateurs. Remove yellowed or damaged leaves at the petiole base as the plant dies back — do not pull, as this can damage the corm.
Zantedeschia jucunda benefits from light pruning after flowering. Remove spent flower stems at the base once blooms fade to redirect energy to the corm. Cut back yellowing foliage as the plant enters dormancy in late summer or autumn. This tidies growth and supports a strong return the following season.

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.
