Corn mint: when to prune it?
In March, cut away the dead stems; in June, cut back by half for fresh leaves if you wish.
Corn mint: how to prune it?
- Leave the faded stems standing over winter: small insects overwinter in them.
- In March, cut them to just above the ground, before the new shoots appear.
- For fresh leaves, cut the plant back by half in June; it soon regrows and flowers afterwards.
- Cut stems with rust down to the ground straight away.
How much to cut, and how often?
- There are 2 pruning periods a year: March and June. You don’t have to prune in every one.
What does it mean for wildlife?
- As a native plant, it feeds more insects than a non-native species.
