Dutchman’s pipe: when to prune it?
In February–March, before new shoots start. It tolerates hard pruning.
Dutchman’s pipe: how to prune it?
- Cut out dead, thin and damaged stems.
- Shorten overlong or rampant shoots to the desired shape.
- To rejuvenate it, cut a few old stems back to about 1 m above the ground; it will shoot again.
- Thin it out so that light and air reach between the leaves.
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.
- 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: Wear gloves: all parts are poisonous. Do not leave prunings lying where children or animals can reach them.
