Japanese rose: when to prune it?
End of winter.
Japanese rose: how to prune it?
- Cut the oldest stems off at ground level and shorten the rest.
- A hedge can be cut back as a whole; it readily regrows from the base.
- Spade off suckers that spread too far, roots and all.
How much to cut, and how often?
- Trim a hedge once or twice a year, after the first flush of growth (late June) and, if needed, in late summer. Check first that no birds are nesting.
What does it mean for wildlife?
- Pruning in March can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
- A dense hedge gives birds a place to nest and shelter, and hedgehogs take cover underneath. Leave some leaves at the base.
- Japanese rose flowers in June–September, when it attracts bees.
- Prunings can go on a dead hedge or brash pile in a corner of the garden: shelter for hedgehogs, wrens and insects.
Common mistakes
- Clipping without first checking for nesting birds.
- Letting the hedge grow wider at the top than at the bottom: the base then goes bare.
Caution: Wear thick gloves and long sleeves. Never dump prunings or suckers in the countryside: they easily take root again.
