When to prune aglaonema 'lady valentine' 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 'lady valentine'
Cut petioles close to the central stem with sterile scissors. Sever flower stalks at the base early to keep the plant's focus on foliage production.
Aglaonema 'Lady Valentine' requires only cosmetic pruning. Trim away yellowed, damaged, or old lower leaves at the petiole base. Remove flower spathes promptly to preserve energy for the striking deep-pink foliage. No structural pruning is needed — this cultivar maintains a naturally bushy, upright rosette without intervention.

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.
