When to prune heart of fire 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 heart of fire
Wear gloves — the leaf margins are extremely sharp. Cut dead outer leaves at the base with heavy-duty sterilised scissors or loppers. Remove the spent central rosette at the base once surrounding pups are several inches tall.
Heart of Fire (Bromelia balansae) is a large, spiny, clump-forming bromeliad that needs very little deliberate pruning. Remove dead or damaged outer leaves with care — the serrated margins are sharp. After the central rosette flowers and dies, it will offset naturally; remove the dead mother plant once pups are 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.
