When to prune urn plant (aechmea fasciata) in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune urn plant (aechmea fasciata)
Cut the spent flower spike at its base with sterile scissors once it has fully faded. Peel or cut away dead outer leaves from the declining mother. When pups are 10-15 cm tall, separate them with a sharp knife, ensuring each has some root material, then pot individually.
Urn Plant (Aechmea fasciata) needs very little pruning. The mother rosette blooms once then slowly dies — this is normal. Remove the spent flower spike at its base once it browns. As the mother declines, pups (offsets) grow from the base; remove dead or browning outer leaves. Harvest pups when they reach one-third the mother's size.

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.
