Purchase a mint plant rather than try growing one from seeds. Be sure the plant has no insects on it.
Repot purchased plant into larger pot. Use a pot large enough for future growth. Add enough potting soil to keep the mint plant near the top of the pot.
Place pot in window or garden. Mint tolerates some shade, but ensure that it receives adequate sunlight.
Mint requires plenty of water. Make sure the pot's soil remains moist at all times. Revive dried plants by placing them in the sun and gradually supplying enough water. Be careful not to overwhelm the delicate plant.
From time to time cut sprigs with larger leaves to start new plants, flavor teas or make mint oil.
Repot mint plants each year to provide sufficient room for proper root development and continued growth of leaves.
