Caucasus catmint (Nepeta grandiflora): when to prune it?
Twice a year: in July after the first flush and in March, before the new shoots appear.
Caucasus catmint (Nepeta grandiflora): how to prune it?
- In July, cut the spent flower stems and part of the foliage back by half; it soon shoots again.
- Leave the stems standing in winter for insects and as protection for the crown.
- In March, cut all old stems to 5–10 cm above the ground.
- Remove dead or damaged parts.
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?
- Caucasus catmint (Nepeta grandiflora) 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.
