When to prune mexican aechmea in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune mexican aechmea
Use clean scissors to trim dead leaves near the base as they brown. When the mother plant is spent, cut it out at the base with a sterile blade, leaving healthy pups undisturbed.
Mexican Aechmea is a monocarpic bromeliad — the mother rosette flowers once then dies. Pruning is limited to removing browning outer leaves as they age and cutting out the dead mother rosette after pups have established. No shaping or regular trimming is needed beyond this routine tidying.

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.
