Mint is an easy plant to grow. It prefers a lightly shaded spot with good, moist soil but will grow almost anywhere under almost any conditions. It grows a vigorous root system that can spread very fast. Mint is best grown in a pot so it doesn’t invade the rest of the garden. You can grow new mint plants by taking a cutting of a mint runner. Just digging down a little at the edge of a clump of mint should loosen up a runner that already has roots, and can be clipped off and used to grow a new plant.
