Mints grow best in rich, moist, well-drained soil. Although they prefer partial shade, a sunny location will do. There are not many growing conditions that deter mint. Allow at least twelve to eighteen inches between plants. If mint starts crowding the garden, simply pull up stems, you can always replant them elsewhere, but be aware that the stem is usually attached to an under ground runner, so it will continue to flourish.
Mints are very aggressive in the garden, spreading by underground runners. Once established in a garden they can be difficult to keep within bounds. One way to control them is to grow them in containers rather than in the ground. Be careful where you place the container. After several years, a container of mint can root into the ground and spread.
