When to prune aglaonema burmese evergreen 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 burmese evergreen
Cut dead or yellowing leaves cleanly at the petiole base using sterile scissors. For leggy, bare stems on mature plants, cut back to a healthy node in spring to encourage new shoots.
Aglaonema brevispathum (Burmese Evergreen) needs minimal pruning. Remove dead, yellowing, or damaged leaves at the base as they naturally occur. This species grows slowly and maintains a tidy upright form. If stems become bare over many years, cut back to a node in spring to stimulate fresh 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.
