When to prune zantedeschia 'captain safari' 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.

Zantedeschia 'Captain Safari' needs deadheading as flowers fade to keep the plant tidy and encourage further blooms. Cut spent spathes off at the stem base. Once all flowering is done and the foliage begins to yellow in late summer, cut the entire plant back to ground level and allow the rhizome to rest.

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.
