When to prune calamondin orange 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 calamondin orange
Cut back overly long stems by one-third to an outward-facing bud. Remove any dead wood, crossing branches, and vigorous water shoots. Use clean, sharp secateurs and wipe with alcohol between cuts if disease is suspected.
Calamondin needs modest annual pruning to prevent legginess and improve air circulation. It fruits on new growth, so cutting back long, unproductive stems after harvest encourages fresh fruiting shoots. Remove suckers from the base promptly. It is naturally compact and does not require heavy reshaping — light tidying is usually enough.

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.
