How to Root Mint Plants

Mint plants are so difficult to kill that even the novice would be hard-pressed to not succeed with rooting them. All mints, with the exception of peppermint, can be grown from seed, but it’s much faster and easier to root stem cuttings from one that you like. Cuttings can be taken from any of the mints whenever they’re actively growing throughout the spring and summer.

Things You'll Need

  • Clean, sharp knife or scissors
  • 3-inch pot
  • Potting soil or compost
  • 1-gallon pot

Instructions

    • 1

      Use a clean, sharp knife or scissors to trim a 6-inch stem just below a leaf node of a healthy mint plant. Put the cut end into water and keep the cutting cool until you can get it planted so that it won‘t wilt.

      Fill a 3-inch pot with potting soil or compost. Set it in a dish of warm water in the sink until the surface feels moist. Remove the pot from the water and let it drain for about an hour.

    • 3

      Strip all of the leaves from the cutting except for one or two sets of them at the top. Plant the lower half of the stem in the pot and firm it gently. Water thoroughly so that the soil surface feels evenly moist, but not soggy or wet.

      Set the cutting outdoors in a brightly lit spot in the shade and don’t allow it to dry out while it’s rooting. The soil should be kept evenly moist, but not wet, at all times. Your mint cutting will root in about two weeks.

      Repot the rooted cutting when you see new growth emerging. Plant it in a 1-gallon pot and bury the pot in a sunny or partially shaded spot in the garden. This will contain the roots of your mint and prevent it from taking over your property.
