Peppermint is a popular herb among home gardeners for its use in teas and homemade soaps and lotions. Gardeners who grow peppermint outdoors will quickly learn how fast peppermint spreads in a growing space. For this reason, many people choose to grow peppermint in containers to prevent it from taking over a garden. Another growing option is to grow peppermint indoors in a pretty container. Find a sunny windowsill or place a peppermint plant under a grow light to provide peppermint for your needs.
Place a small amount of gravel over the bottom of the container to cover the drainage hole. Fill the container almost full with potting soil.
Sprinkle approximately 10 seeds over the top of the potting soil. Lightly cover the seeds with approximately 1/8-inch of potting soil.
Spray the surface of the potting soil generously with water to moisten the soil. Keep the soil evenly moist during the entire germination time.
Watch for the seedlings to sprout and place the container under the grow light after the seedlings emerge from the soil. Place the grow light 2 to 4 feet above the seedlings. If you are using standard fluorescent light bulbs, place them 2 to 4 inches above the seedlings.
Thin the seedlings when they are approximately 2 inches high. Keep the two strongest seedlings in the container and discard the rest. Make sure the seedlings are positioned so they are as far apart as possible in the container.
Decrease the amount of water you give the peppermint plants now. Wait until the soil is completely dry before you water each time.
Give the peppermint plants approximately two hours of sunlight or time under a grow light and keep the plant in a location that stays approximately 70 F.
