When to prune pineapple bromeliad 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.

Cut the spent flower stalk at its base with sterilized shears. Trim dead or badly damaged leaves back to the stem. Wear gloves to protect against the spiny leaf margins. Mature pups can be prized off and potted in a very fast-draining mix.
Pineapple Bromeliad (Acanthostachys strobilacea) needs minimal pruning. This pendant, epiphytic bromeliad flowers and then produces pups.

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.
