When to prune aglaonema (chinese 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 (chinese evergreen)
Cut individual leaves off cleanly at the base of their petiole. For a leggy stem, cut the cane back to a healthy leaf node using clean scissors or a blade. Remove flower spikes at the base as soon as they appear if you want to preserve foliage vigour.
Aglaonema rarely needs pruning. Remove any yellow, brown, or damaged leaves at the base as they appear. Leggy plants can be cut back to a lower leaf node to encourage a bushier habit, but this is infrequent. Flower spikes (spathe/spadix) can be removed as they are not ornamental and drain energy.

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.
