When to prune begonia 'maori haze' 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 begonia 'maori haze'
Pinch stem tips just above a node using clean fingers or sterilised scissors to promote bushier growth. Remove dead leaves and spent flower stalks at the base. Ensure good airflow after pruning — rex begonias are prone to powdery mildew in stagnant air.
Begonia rex 'Maori Haze' benefits from light, regular pruning to stay bushy. Pinch back leggy stems in spring or summer to encourage compact, multi-branched growth.

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.
