Catnip: when to prune it?
Twice a year: in July after the first flush, and in March to remove the old stems.
Catnip: how to prune it?
- In July, cut the faded stems back by about half: it regrows quickly and flowers until September.
- Remove spent spikes before they set seed if you do not want seedlings.
- Leave the dead stems standing in autumn: they protect the base in winter.
- In March, cut all old stems down to just above the new shoots at the base.
How much to cut, and how often?
- There are 2 pruning periods a year: March and July. You don’t have to prune in every one.
What does it mean for wildlife?
- Catnip flowers in June–September, when it attracts bees and butterflies.
- If pruning falls during flowering, wait until it is over or leave part of the plant to flower, so bees and butterflies still benefit.
