When to prune peperomia maculosa 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 peperomia maculosa
Pinch or snip stem tips just above a leaf node with clean scissors to encourage branching. Remove dead leaves cleanly at their base.
Peperomia maculosa (Radiator Plant) is an upright, compact houseplant that needs very little pruning. Remove dead, yellowing, or damaged leaves and spent flower spikes as they appear. If any stems grow leggy, pinch them back in spring to encourage a fuller, more compact habit.

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.
