Mint is easy to propagate from root cuttings in autumn.
Once taken, the cuttings can be grown on in pots indoors to make new plants. The roots and underground stems of mint are the best parts to make cuttings from, and you can also use this method on tarragon, sweet woodruff and horseradish.
You Will Need
- Hand fork
- Sharp knife
- Multi-purpose, peat-free compost
- Horticultural grit
- Seed tray or small pots
Use a hand fork to expose thick roots or stolons around the edge of the plant and cut off long pieces for cuttings.
Cut them into short, 2-3cm lengths using a sharp knife. Discard thin, weak pieces.
Fill a seed tray by two thirds with a 50:50 mix of multi-purpose compost and grit. Lay cuttings on the surface, then cover with more compost and water.
Grow mint in pots or containers
Mint is a very vigorous plant. Grown in the ground it can quickly spread and run riot, so is best grown in a pot or container where it can’t escape.
