When to prune large-cupped billbergia 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 large-cupped billbergia
Cut dead leaves close to the base with clean scissors. Use a sterile, sharp blade to sever the spent mother rosette at soil level without disturbing surrounding pups.
Large-Cupped Billbergia needs only basic housekeeping. As a monocarpic bromeliad, each rosette flowers once then slowly dies while producing offsets. Remove dead or yellowing leaves as they appear. Once pups are at least one-third the size of the mother and she is fully spent, cut the old rosette away at the base.

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.
