When to prune aglaonema 'sparkling sarah' 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 'sparkling sarah'
Use clean scissors to sever petioles at the stem. Remove flower stalks early to maintain strong leaf colour and density.
Aglaonema 'Sparkling Sarah' is low-maintenance and rarely needs pruning. Remove discoloured or damaged leaves by cutting the petiole close to the stem. Snip flower spathes at the base as they emerge to focus the plant's resources on producing its vivid pink-and-green foliage. No shaping cuts are typically required.

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.
