UK pruning guide · RHS timing
When to prune regel's nidularium 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 regel's nidularium
Cut dead or brown leaves at the base using sterilised scissors. Remove the declining mother rosette at soil level post-bloom, ensuring pups are stable before doing so.
Regel's Nidularium is a tidy rosette bromeliad that needs very little pruning. Remove dead or damaged outer leaves at the base whenever they appear. As with all Nidularium, the mother plant blooms once then declines; remove it cleanly after flowering once the offset pups are well established.

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.
