When to prune guzmania wittmackii 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 guzmania wittmackii
Cut the faded spike near its base with clean, sharp scissors. When the mother rosette is entirely spent, cut it away at soil level with a clean blade, avoiding damage to any pups nearby.
Guzmania wittmackii is a monocarpic bromeliad requiring very little pruning. After the striking flower spike fades and browns, trim it back for neatness. The mother rosette will gradually yellow and die over several months; remove it cleanly at the base once fully spent. Grow on any pups that have emerged.

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.
