When to prune aglaonema modestum 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 modestum
Use sterile scissors to cut dead or yellowing leaves at the petiole base. For leggy stems after years of growth, cut back to a healthy node — new growth will emerge from below the cut.
Aglaonema modestum (Chinese Evergreen) is a slow-growing, undemanding houseplant. Pruning is limited to removing yellow, brown, or dead leaves at the base as they occur. Older plants may develop bare lower stems over many years; cut these back to a node in spring to refresh the plant.

When should I prune aglaonema modestum in the UK?

Is it illegal to prune aglaonema modestum in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to aglaonema modestum, since birds do not nest in it. The Wildlife and Countryside Act 1981 still protects any active nest you do find anywhere in the garden — the rule is about the nest, not the plant.
How do you prune aglaonema modestum?

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.
