Black bryony: when to prune it?
In February–March, before the new shoots appear.
Black bryony: how to prune it?
- Pull the dead, dried stems out of the hedge; they come away easily.
- Leave them until the end of winter: the berries are winter food and the stems shelter insects.
- Wear gloves: even dried berries and stem remains are poisonous.
- Ideally prune the hedge it climbs in at the same time, before it starts growing again.
How much to cut, and how often?
- One pruning period a year: February–March.
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.
- As a native plant, it feeds more insects than a non-native species.
- 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.
Caution: Do not cut living stems in summer without good reason: the plant needs its leaves to fill up its tuber.
