Mints have wide-spreading underground and overground stolons and erect, square, branched stems. All mints thrive near pools of water, lakes, rivers and cool moist spots in partial shade. Mint can also be grown in full sun. Mint grows all year round. To control mints in an open environment, they should be planted in deep, bottomless containers sunk in the ground or planted above ground in tubs and barrels.
The most common and popular mints for cultivation are peppermint, spearmint and apple mint. Mints are supposed to make good companion plants, repelling pesty insects and attracting beneficial ones. Harvesting of mint leaves can be done at any time. Fresh leaves should be used immediately or stored up to a few days in plastic bags in a refrigerator.
