4" Pot Herb - Spearmint
Spearmint is a hardy perennial up to USDA plant hardiness Zone 5 that grows best in partial shade with well-draining, rich, moist soil. Spearmint, once planted, takes off quickly and can take over quickly as well. Many people question how to plant spearmint due to its invasive nature. Some cautious gardeners grow spearmint in hanging baskets or containers to avoid having to pull out runners constantly. Another way to plant spearmint if you want it in the garden is to plant it in a 5-gallon (18.9 L.) pot with the bottom cut out. This will help keep the runners of growing spearmint plants from invading other spots of your garden.
