When to prune compassion rose 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 compassion rose
Cut main canes back by one-third; reduce flowered laterals to 2–3 buds. Remove any dead, weak or rubbing stems entirely, cutting to the base. Tie new long canes horizontally or at a gentle angle to maximise flowering spurs.
Compassion is a repeat-flowering climbing rose that needs annual pruning to maintain vigour and encourage reblooming. Remove dead, diseased, and crossing stems, then shorten sibling laterals. Tie in new canes to a support. Without pruning it becomes congested and flowering declines markedly.

Pruning compassion rose in the UK — FAQ
When should I prune compassion rose in the UK?
Prune compassion rose in early to mid spring. 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.
Is it illegal to prune compassion rose 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 compassion rose 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.
