When to prune eternal flame plant 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 eternal flame plant
Snip spent flower stalks at the base with clean scissors once the orange bracts fade. Remove yellowed or damaged leaves by cutting the petiole cleanly near the soil line.
Eternal Flame Plant benefits from deadheading spent flower spikes to encourage further blooming and keep the plant tidy. Remove individual damaged leaves as with all Calatheas. No structural pruning is needed — the plant grows from a rhizome. Cutting spent flowers promptly can prolong the blooming display.

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.
