Takes just:

30 minutes

As the weather turns colder in autumn, it's sensible to be prepared and insure your precious herbs against damage from winter cold and wet.

You can take semi-ripe cuttings from shrubby herbs such as lemon verbena (Aloysia citrodora) and rosemary, or divide low-growing herbs such as Corsican mint (Mentha requienii) and overwinter them in small pots, in a cold frame or cold greenhouse.

The following steps can also be used for lawn chamomile and pennyroyal (Mentha pulegium).

You will need

  • Large modules
  • Compost mix
  • Corsican mint


Fill modules with a cuttings compost made from one-third fine-shredded bark, on-third perlite, and one-third multi-purpose potting compost. Firm in well. Dig up some Corsican mint, or remove side shoots from a pot-grown plant and cut into sections, each with some roots attached. Cut off excess roots or top growth.

Gently push the roots into a hole in the compost. Back-fill with more compost and firm so that the top growth is on the surface. Water well and place in a cold greenhouse, or on a cool windowsill. Don't let the compost dry out.
