Wild teasel: when to prune it?
Real pruning is not needed. In March, cut down the dead stems once the birds have eaten the seed; in September you can remove some of the heads to limit self-seeding.
Wild teasel: how to prune it?
- In March, cut the dead stems of second-year plants off at ground level, or pull the whole plant out, root and all.
- For fewer seedlings, cut off some of the heads in September before the seed ripens, and leave a few for the goldfinches.
- For dried arrangements, cut heads with a long stem as soon as they turn brown.
- Leave this year’s green rosettes: they will flower next year.
How much to cut, and how often?
- There are 2 pruning periods a year: March and September. You don’t have to prune in every one.
What does it mean for wildlife?
- Wild teasel flowers in July–August, when it attracts bees and butterflies.
- As a native plant, it feeds more insects than a non-native species.
Caution: The plant dies after flowering: that is normal for a biennial.
