How to Propagate Catnip

some love her, while others are happy when she has finally disappeared from the garden. Over self-seeding, the catnip multiplies gladly and quickly in self-direction. But you can also take the propagation into your own hands.

Method 1: Sowing

Catnip produces numerous small seeds after flowering. So they become new herbaceous perennials:

    • collect in autumn and sow in spring
    • easily cover with nutrient-poor soil
    • ideal germ temperature: 20 °C
    • keep earth moist
    • after 2 to 3 weeks the seeds


  • plant out after the ice saints

Method 2: Division

Another method is the sharing of catnip. Over the years, a small perennial plant becomes a plant that takes up a lot of space and loses its vigour over time. Therefore it is advisable to divide the catnip every 2 to 3 years.

The best period has come between April and June. The old plant is being dug up. Then take a spade and separate the plant once in the middle. The root balls are generously watered before planting. Then they grow good.

Method 3: Propagation of cuttings

In early spring or in autumn, for example during the annual pruning of the plant, the cuttings can be propagated. This method is the most common, fastest and most effective.


  • to cut off a 7 to 10 cm long shoot
  • Remove lower leaves
  • Place cuttings into a glass or vase with water
  • leave in a bright, warm place – Attention: not within cat’s reach)
  • Replace water regularly to prevent rotting
  • when rooted in soil plants

Tips & Tricks

There are varieties which cannot be propagated by sowing or only with difficulty. These include, for example, the catnip/bluehead and the white-flowering catnip.
