Wild parsnip: when to prune it?
In August–September: after flowering if you want to limit self-seeding, or after seed set.
Wild parsnip: how to prune it?
- In a wildflower meadow, leave some of the stems with seed standing into winter: the hollow stems shelter insects.
- If you want fewer seedlings, cut off the umbels as soon as they have finished flowering, before the seeds turn brown.
- Mow the rest of the meadow in September and remove the cuttings.
- Always work with gloves and long sleeves, ideally on a cloudy day or in the evening.
How much to cut, and how often?
- One pruning period a year: August–September.
What does it mean for wildlife?
- As a native plant, it feeds more insects than a non-native species.
Caution: The sap makes skin sensitive to sunlight. Never cut it with a strimmer without protective clothing: it sprays sap onto arms, legs and face.
