Cultivation: Seeds can be sown in flats or in the ground. Plants also can be propagated by cuttings. Place cuttings in a medium, keep moist, and transplant once the root system is well established. Spearmint spreads rather quickly by runners. Contain the plants in pots buried to the rim or grow in a large area where they can spread. Frequent cutting or mowing of large plots will keep mints at their prettiest. In late fall, cut back to the ground and mulch if winters are severe.

Garden notes: To curtail spreading, we planted our 4-inch seedlings in 5-gallon pots with the bottoms cut out and buried the pots in the garden with about 1 to 2 inches of rim exposed. We also removed creeping runners whenever they invaded neighboring areas. The runners wrapped themselves around the inside of the pot many times despite our diligent efforts.
