You can find mint seeds at your local garden center or online. Once you have your seeds, plant them in a small pot or seed tray. Cover the seeds lightly with soil and water regularly to keep the soil moist. It’s important to keep the soil moist but not too wet, as mint doesn’t like to be overwatered. You should see sprouts within a week or two.

Here’s how to plant peppermint seeds inside: Get some small, individual pots or a seed flat. I personally think a seed flat is easier, especially if you’re growing more than one plant Place a small layer of prepared soil into the container Sow the seeds about 1/4 inch deep into the soil

Pot up your mint plant with a good potting mix, either a regular commercial type or one with equal amounts of sand, peat, and perlite mixed in. Water the mint plant well after planting and place it in an area with indirect light, preferably an east-facing window during spring and summer or a west or south-facing one in fall and winter.

You can grow mint from seed, with mint seeds regularly available in garden centers or online. Sow the seeds thinly in compost, keep them moist, and the seeds should germinate within a few weeks at 70˚F.
