When to prune aglaonema legacy 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 legacy
Snap or cut yellowing petioles cleanly at the base. Cut flower stems before they fully open if foliage display is the priority. Leggy canes can be cut back to 10–15 cm above the soil — stumps resprout reliably.
Aglaonema 'Legacy' requires minimal pruning. Remove yellowing lower leaves and any flower stalks that appear — the blooms are inconspicuous and take energy from the foliage. The plant rarely becomes unruly indoors. If it does grow leggy over many years, a stem cutback to a node in spring will reinvigorate it.

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.
