When to prune billbergia zebrina 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 billbergia zebrina
Cut the faded flower spike to its base with clean secateurs. Once the mother rosette browns and dries, use a clean knife to separate offsets that have developed their own roots, then pot them in a fast-draining bromeliad mix.
Billbergia zebrina is a clumping bromeliad needing minimal pruning. Trim away the spent flower spike once blooming is done. The mother rosette declines after flowering — remove it when pups at the base are well rooted and large enough to sustain themselves. No regular cutting schedule is needed.

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.
