Heirloom Herb. Learning how to grow spearmint isn’t much different than growing other mint plants. Spearmint is a hardy perennial plant that grows best in partial shade with well-draining, rich, moist soil and a pH of 6.5 to 7.

 

Mint is easiest to grow from plants, but you can sow seed once the ground has warmed in the spring. Keep seeds moist until they germinate and thin plants to 1 foot (30 cm.) apart. 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 kl.)pot with the bottom cut out. This will help keep the runners of growing spearmint plants from invading other spots of your garden.

 

Perennial hardy to Zone 5 when grown in quickly draining soil under full sun.

 

How to Grow

2800 seed/gram. Sow Spearmint seeds directly outdoors in a sunny site with average soil in mid-to-late May or again in mid-August through to mid-September. In spring, the seed can also be started indoors on the surface of a soil-less mix 8-10 weeks before the last frost date. Keep the temperature at 21°C (70°F) for the 10-20 day germination period, then grow on under drier conditions at a slightly cooler temperature before hardening off and transplanting outside after the danger of frost has passed. Sow seed no more than 3 mm (1/8″) deep and 2.5 cm (1″) apart then thin the sprouts to 20 cm (8″) apart in the garden.
