How to Plant Peppermint Cuttings

Peppermints cannot reproduce on their own, so to create more plants, you need to divide, layer or plant cuttings. Once peppermint is planted, however, it sends out runners and can populate or overrun an entire bed. Peppermints are propagated easily with cuttings, and if you properly plant the cuttings, you can have a new plant, or even an entire peppermint bed, in little time.

Instructions

    • 1

      Find a healthy peppermint plant in the summer that is growing vigorously without any signs of disease. Pinch off a stem and place it in a glass of water until you can plant it.

    • 2

      Fill a small pot with a potting medium, such as a mix of half perlite and half peat. This will provide enough aeration and water retention for the cutting to grow roots.

    • 3

      Apply an IBA rooting hormone to the base of the peppermint cutting, remove the leaves from the bottom half of the plant and stick the plant into the rooting medium about one-third of its length. Tamp the medium down around the base of the plant.

    • 4

      Water thoroughly after planting. Place a gallon-size plastic bag over the top of the plant to retain humidity, then put the plant in an area with filtered sunlight. Keep the cutting moist, but not soaking, until it starts to take root and grow on its own.

    • 5

      Remove the plastic bag as new leaves start to grow. Wait until the roots are well established in the soil, then transplant the plant to a pot or outdoors.
