How to Plant Mint From Seeds

Use large pots to plant mint seeds indoors. If planting outside, place a barrier, such as a bottomless plastic pot, between the mint and other herbs and plants. Mint grows forcefully, overrunning other plants quickly, if allowed. Place the bottomless pots at least 12 inches away from each other and about 1 foot under the ground.

Plant mint seeds in the spring, after the chance of frost passes, if planting outside. Dig a hole 2 inches deep and place the mint seeds in the hole. Cover with soil.

Water the freshly planted seeds. The key for mint to grow well is to keep the soil moist. Mint grows well in direct sunlight or partial shade. Keep the mint well-watered if grown under direct sunlight.

Harvest mint when its flowers bloom. Use pruners to cut the leaves and stem from the top of the plant when the leaves are still moist in the morning. Do not cut from the bottom of the plant, as this discourages new growth.

Use a natural pesticide on the mint plant. Spray only if insects, such as flies or beetles, become problematic. Harmful rust forms on the underside of the leaves. Check regularly and remove the leaf/leaves if you find orange spots.
