When to prune spathiphyllum 'mauna loa' 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 spathiphyllum 'mauna loa'
Cut spent flower stalks off at the base. Trim brown leaf tips at a slight angle following the leaf's natural shape. Remove entirely any fully yellowed or dead leaves at the base.
Spathiphyllum 'Mauna Loa' needs very little pruning. Remove spent flower spathes once they turn green and then brown, cutting the stem at the base. Trim yellowing or brown leaf tips with sharp scissors. No hard pruning is ever required — the plant does not produce woody stems, and cutting back healthy leaves stresses it.

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.
