When to prune natal plum bonsai in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune natal plum bonsai
Remove dead, damaged, or inward-crossing branches after flowering. Trim new growth regularly to keep the silhouette compact. Never strip an entire branch of all foliage. Use caution when wiring older branches as they become brittle; check wires frequently due to rapid growth.
Natal Plum bonsai benefits from regular pruning — it grows vigorously, especially in warm climates, and responds by budding back strongly. Prune after the flowering period to maintain a compact, bushy structure. Light trimming can be done year-round. Never remove all foliage from a branch, as this causes dieback on that branch.

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.
