Mint is an easy herb to grow. It can be grown from seeds, cuttings or small plants. For more general information on planting herbs, read Planting Herbs in a Garden.

Seeds and Transplanting:

You can start mint indoors any time of the year.

1. After purchasing mint seeds, (click here for mint seeds from , prepare the starter kit. One recommended complete kit is the Jiffy Seed Starting Greenhouse Kit from Amazon, or use any seed starting tray with peet pellets or seed starter soil. A homemade seed starter soil will consist of equal parts sand, peat, and perlite mixed together.

If the starter soil you have is dry, moisten the soil over night so it is moist but not dripping wet.

Fill the starter tray 3/4 of the way to the top of each section. Be sure each section of the tray has a drainage hole.

2. Mint seeds are very tiny, so do your best to place just a few seeds on the top of each section. Cover them with a very thin layer of vermiculite. The seeds germinate best when exposed to the heat.

3. Place the tray in a bright sunlit room where it will receive consistent heat. The seeds prefer room temperature or slightly warmer, between 68 and 75 degrees Fahrenheit (20 degrees to 23.9 degrees Celsius).

4. Mist your tray every day to keep the soil moist until the seeds germinate.

5. It can take up to 3 weeks for the seeds to sprout. Normally they germinate within 10 to 15 days.

Sprouting Seeds:

1. Once the sprouts have 2 complete leaves, you can thin out each section of the tray to have one stem standing.

2. After the sprout has 4 or more complete leaves, it is time to transplant it into a larger pot.

3. Transplant them into a 6 to 10 inch diameter pot full of rich, moist, well drained soil.

Tip Cuttings and Plant Division:

Tip Cuttings:

The tip cutting technique to propagate more mint plants is very simple. It’s a wonderful way to create a new plant and offer it to a friend, family member, or just to have another plant!

Simply cut a 5 to 6 inch top section of a stem from above a leaf shoot. Remove the bottom 2 to 3 inches of leaves and place it in a glass of water in a window that receives at least 4 to 6 hours of full sun each day. Watch it grow root tendrils. When the root tendrils are about an inch or two long, plant it into a pot using the method described above.

This is a great science lesson for a young child!

Division of Plants:

If your plant is rather large, divide the plant into sections and transplant each section.

Remove the mint from the pot.

Find a spot where you can easily tear it apart. With your hands grab the roots and the leaves and tear apart.


Buy an Already Established Mint Plant:

You can always take the easy route and purchase an already established plant. After you bring it home, transplant it into a 10 inch diameter pot with a drainage hole and follow the directions above.

Easy peasy!

General Tips About Mint

  • Do not allow the plants to flower and seed.

How to Care for Your Mint Plant

3. If the plant is not placed in a humid room, place the pot on a tray filled with pebbles and water.
