When to prune begonia 'silver limbo' 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 'silver limbo'
Snip dead petioles flush to the rhizome with clean scissors. If the rhizome grows out of bounds, cut the offending tip back to keep the plant within its container. Never remove large numbers of healthy leaves at once.
Begonia rex-cultorum 'Silver Limbo' is a Rex begonia valued for its silver-patterned leaves. Pruning is minimal. Remove dead or yellowing leaves cleanly at the petiole. Trim any rhizome that has crept excessively beyond the pot edge in early spring. Avoid cutting back healthy leaves — Rex begonias are grown for their foliage and do not need structural pruning.

Pruning begonia 'silver limbo' in the UK — FAQ
When should I prune begonia 'silver limbo' in the UK?
Prune begonia 'silver limbo' in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

Is it illegal to prune begonia 'silver limbo' in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to begonia 'silver limbo', since birds do not nest in it. The Wildlife and Countryside Act 1981 still protects any active nest you do find anywhere in the garden — the rule is about the nest, not the plant.

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.
