UK pruning guide · RHS timing
When to prune gryphon begonia 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 gryphon begonia
Pinch stem tips just above a node to encourage bushiness. Cut leggy stems back by up to one-third using clean, sharp scissors. Remove spent flower stalks at their base.
Begonia 'Gryphon' is a vigorous cane-type hybrid that responds well to pruning. Pinch stem tips regularly to keep the plant full and prevent legginess. Cut back any stems that become bare or elongated. Removing spent flower stems tidies the plant and can redirect energy to foliage, which is its main ornamental draw.

Is it illegal to prune gryphon begonia in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check gryphon begonia for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
