When to prune spring cyclamen 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 spring cyclamen
Twist spent flower stems and yellowed leaves free from the tuber surface — they detach easily when dry. Avoid cutting near the tuber. Leave the dormant tuber undisturbed in dry soil through summer.
Spring Cyclamen (Cyclamen coum) needs no active pruning. After flowering in late winter to spring, leaves and stems die back naturally as the tuber enters summer dormancy. Simply pull away dried stems and leaves with a gentle tug. Do not cut healthy foliage or disturb the resting tuber through summer.

Pruning spring cyclamen in the UK — FAQ

Is it illegal to prune spring cyclamen 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 spring cyclamen 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.
