When to prune pelargonium 'deacon fireball' 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 pelargonium 'deacon fireball'
Snap off spent flower clusters at their base. Pinch stem tips just above a node in spring for additional branching. Trim stems back by one-quarter in late summer with clean secateurs — Deacon types need only a light trim, not a hard cutback.
Pelargonium 'Deacon Fireball' is a Deacon series miniature zonal with vivid red double flowers. Like all Deacon varieties, it has a naturally compact, self-branching habit that needs little pruning. Deadhead consistently for continuous bloom. A light tip-pinch in spring boosts branching further. Trim lightly by one-quarter before overwintering indoors.

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.
