Japanese wineberry: when to prune it?
After the harvest, in August–September.
Japanese wineberry: how to prune it?
- As for blackberries: a stem fruits only once, in its second year. After the harvest, cut the fruited stems off at ground level.
- Tie in 4–6 strong young stems to the wires for next year; the rest can go.
- Also remove thin, weak and crossing stems.
How much to cut, and how often?
- One pruning period a year: August–September.
- Prune in moderation: never remove more than about a third of the shrub at once.
What does it mean for wildlife?
- Pruning in August can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
- 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.
- Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.
Caution: The stem tips root where they touch the ground: that is how it easily escapes from gardens.
