Growing and Harvesting Mint
If you are planning on planting mint, do so in a container to restrict its root growth. It is known as an invasive species for a reason. A perennial herb, mint will grow in most conditions, but it thrives in damp, moist soil with partial shade.
Mint will grow anywhere from 10 to 120 cm tall and its leaves can be harvested at any time. Fresh mint leaves should be used immediately or stored up to a couple of days in a plastic bag in the refrigerator.
If you buy a bunch of fresh mint, it should be placed in a container of water, stems down, with a plastic bag loosely covering the top. Ideally change the water every two days and the mint should stay fresh for up to a week.
Dried mint leaves should be stored in an airtight container and placed in a cool, dark, dry area.
