When to prune firecracker 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 firecracker plant
Pinch or cut stem tips back by one-quarter, cutting just above a leaf node. Remove thin or bare stems entirely at the base. Avoid cutting back into completely leafless old wood.
Firecracker plant (Gesneria cuneifolia) can become leggy in low light and benefits from periodic pinching. After a flush of tubular blooms, trim stem tips back to a healthy pair of leaves to encourage branching and a fuller habit. Remove any dead or weak stems at the base. This tropical gesneriad tolerates light pruning well.

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.
