Water regularly, allowing the soil to dry out slightly between waterings. Nepeta nepetella prefers well-drained soil and is somewhat drought-tolerant once established. Avoid overwatering, which can lead to root rot.

Water more frequently during prolonged dry spells and less in cooler, damp weather.

Prune back flowering stems after the first flush of blooms to encourage a bushier habit and a second flowering. Cut back by about one-third to one-half.

A more significant cut to the ground can be done in late autumn or early spring to remove dead foliage and shape the plant.

Lesser catmint is easily propagated from seed sown in spring or from stem cuttings taken in late spring or early summer. Seeds can be sown directly into the garden or started indoors.

Cuttings should be rooted in moist, well-drained potting mix.

Repot Nepeta nepetella when it becomes root-bound, typically every 2-3 years. Choose a pot only slightly larger than the current one with ample drainage holes. Use a well-draining potting mix.

Repotting is best done in spring before new growth begins.
