How to grow mint
Take a cutting from a pre-existing mint plant.
Mint is difficult to grow from seed, and it is virtually impossible for some varieties, like peppermint. Cut a 4 inch (10 cm) sprig about inch (1 cm) above a junction to allow new branches to grow in its place.

Select from the following. (1). When harvesting fresh mint, you'll need a very small wire cutter or other tool that will allow you to cut at a roughly 8 inch (20 cm) range. Till weekly, remove plants every two weeks, and prune clippings shortly after planting. (2). The sprig does not need to have many leaves, and almost any sprig will do. Place the sprig in a glass of water, and remove any leaves that fall below the water line. (3). If you live in a place where there is only a handful of mint plants each year, it's best to plant from a larger bush. This makes it easier for new growth to grow and limits the risks of potential diseases. (4). If you are already growing mint, you should only cut the sprig from seeds, as a slight revolution of stem will cause the same result and disturb mint root growth. Remove a flower stem from the mint.
The answer is:
(2).
