When to prune blood orange moro in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune blood orange moro
Remove water sprouts flush to the trunk or branch collar, thin crossing interior branches to improve light penetration, and cut dead or diseased wood to healthy tissue. Aim for a vase-shaped canopy with an open centre. Container plants can be lightly headed to limit height.
Blood Orange 'Moro' is pruned like other sweet oranges: light annual shaping to maintain an open canopy and remove unproductive or crossing wood. Water sprouts should be removed promptly. Avoid heavy pruning, which pushes excessive vegetative growth at the expense of fruit. The deep pigmentation is temperature-driven and not affected by pruning timing.

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.
