Total time:

Step 1

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.

Step 2

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.
