Method 1: Growing Mint from Cuttings

Starting mint from cuttings is a simple and effective way to grow this herb indoors. It’s also a great method to propagate an existing mint plant.

Step-by-Step Guide:

  1. Take a Cutting:
  • Find a healthy mint plant and snip off a 4-6 inch cutting just below a node (where leaves grow from the stem). Ensure the cutting has several sets of leaves.
  1. Prepare the Cutting:
  • Remove the lower leaves from the bottom half of the cutting. This encourages root growth and prevents leaves from rotting in water.
  1. Root the Cutting:
  • Place the cutting in a glass of water, ensuring the lower part is submerged but the upper leaves stay above water. Place the glass in a bright spot but out of direct sunlight.
  1. Monitor Root Development:
  • Within a week or two, you should see roots developing. Once the roots are a few inches long, the cutting is ready to be transplanted.
  1. Transplant to Soil:
  • Fill a small pot with well-draining potting mix. Make a hole in the soil and gently plant the rooted cutting. Water it well and place the pot in a location with indirect sunlight.

Care Tips:

  • Keep the soil consistently moist but not waterlogged.
  • Trim the plant regularly to encourage bushier growth and prevent legginess.

Method 2: Growing Mint in Pots

Growing mint in pots from seeds or seedlings is another straightforward method. This approach allows you to start fresh and ensure your mint plant has optimal growing conditions.

Step-by-Step Guide:

  1. Choose a Pot:
  • Select a pot with good drainage. Mint prefers well-draining soil to prevent root rot. A pot with a diameter of at least 8-10 inches is ideal for allowing the mint to spread.
  1. Prepare the Soil:
  • Use a high-quality potting mix. You can mix in some perlite or sand to improve drainage if needed.
  1. Planting Seeds or Seedlings:
  • If planting seeds, scatter them on the soil surface and cover lightly with a thin layer of soil, about 1/4 inch deep. For seedlings, make a small hole in the soil and place the seedling in it, then firm the soil around the base.
  1. Watering:
  • Water the soil thoroughly after planting. Keep the soil consistently moist, especially during the germination phase if you’re growing from seeds.
  1. Light Requirements:
  • Place the pot in a sunny spot, such as a windowsill that gets plenty of indirect sunlight. Mint needs at least 4-6 hours of light daily. If natural light is insufficient, consider using a grow light.

Care Tips:

  • Regularly pinch off the tops of the mint stems to promote bushier growth.
  • Rotate the pot occasionally to ensure even light exposure on all sides of the plant.

Method 3: Hydroponic Mint Growing

Hydroponics is a method of growing plants without soil, using nutrient-rich water instead. This method is efficient and can yield faster growth.

Step-by-Step Guide:

  1. Set Up a Hydroponic System:
  • Choose a hydroponic system suitable for herbs. A basic setup includes a container, a water pump, an air pump, and a growing medium like perlite or vermiculite.
  1. Prepare the Nutrient Solution:
  • Mix a balanced hydroponic nutrient solution according to the instructions. This solution provides all the necessary nutrients for the mint to thrive.
  1. Plant the Mint:
  • Take mint cuttings or seedlings and place them in the growing medium within the hydroponic system. Ensure the roots are in contact with the nutrient solution.
  1. Light Requirements:
  • Provide adequate light, either natural or artificial. Mint requires 12-14 hours of light daily in a hydroponic system. LED grow lights are an excellent choice for indoor hydroponic gardens.
  1. Monitor and Maintain:
  • Regularly check the water levels and nutrient concentration. Refill and adjust as necessary to keep the plants healthy. Ensure the pH level of the nutrient solution stays between 5.5 and 6.5.

Care Tips:

  • Prune the mint regularly to prevent it from becoming too leggy and to encourage fuller growth.
  • Keep the hydroponic system clean to prevent algae growth and disease.


Growing mint indoors is a rewarding experience that ensures you have fresh, aromatic leaves whenever you need them. Whether you choose to grow mint from cuttings, in pots, or using a hydroponic system, each method has its benefits and can yield a bountiful harvest.
