How to Propagate Mint Plants

Purchase a small mint plant to propagate from your local nursery if you don't have one already. Mint is challenging to grow from seed, and a healthy mint plant will give you a more stable crop.

Take several cuttings of your mint plant to propagate, using the scissors. For best results, choose long stems to cut and remove at least 4 inches with a clean snip through the stem.

Place these cuttings in a vase with water and allow to sit until the stems start developing small roots, usually within 1-2 weeks. During this time, refill the water as it evaporates and place the vase in a sunny location.

Fill your empty pot 3/4 of the way with potting soil when the mint cuttings have grown new roots. Since mint is a fast growing herb, you should choose a plant that is larger than your mint plant so you don't need to re-pot within a couple months. Try a 6- to 8-inch pot if you begin with a 3-inch plastic pot.

Place the mint seedlings in the new pot. Fill the pot the rest of the way with potting soil.

Water the new plant before placing it in a sunny location. Water the plant periodically so that the soil is moist.
