How to Grow Mint Indoors

Growing Mint Indoors in Soil

• 1

  Select a 4-inch pot with good drainage.

• 2

  Provide mint with quality potting mix that includes vermiculite or perlite to help retain moisture.

• 3

  Fill the pot 3/4 full of potting mix and add mint cuttings or a small plant and top with soil.

• 4

  Press the soil in place to remove any air pockets.

• 5

  Mint likes moisture, so include a 1/2-inch layer of mulch on top of the soil.

• 6

  Keep mint plants uniformly moist at all times. If watering will be an issue, consider adding water-retaining polymers to the soil or add wicks and a dish reservoir.

• 7

  Offer mint good indirect light from a southern or western-facing window in winter, or an eastern-facing window in summer.

• 8

  Harvest small sprigs of mint after the first month. Don't take more than half the foliage over the winter season.

Growing Mint in Water

• 9

  Place 6-inch long mint cuttings in a glass jar filled 3/4 full of tepid water.

• 10

  Add liquid fertilizer according to manufacturer's instructions.

• 11

  Place the jar in a window that receives six hours of light each day.

• 12

  Replace water once a week.

• 13

  Clean and wipe down the jar if it develops algae growth.

• 14

  Harvest no more than half the length of the sprig over the winter, and only that if you see new growth sprouting. By spring, the cuttings should have vigorous root growth and can be planted in the garden or into a pot for indoor use.
