When to prune aglaonema super white in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune aglaonema super white
Cut spent leaves and flower stalks cleanly with sterilised scissors at the petiole base. Avoid heavy pruning — 'Super White' grows slowly and highly variegated cultivars can struggle to recover from aggressive cuts.
Aglaonema 'Super White' needs very little pruning. Its pale, low-chlorophyll leaves make it more sensitive than green cultivars, so unnecessary cutting is unwise. Simply remove any yellowing or browning leaves at the petiole base as they appear. Remove flower spikes promptly to keep energy in the foliage.

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.
