When to Plant Mint

Understanding your regional temperatures is crucial when planning to grow mint from seed. While mint plants are generally cold-hardy, young seedlings may be vulnerable to harsh winter weather in certain regions.

In USDA Hardiness Zones 4 to 9, it is best to plant this perennial herb in the spring, after the threat of frost has passed. This can be done either by starting seeds indoors or outdoors, in the ground or in containers.

Two months before the last predicted frost date for your area, sow seeds indoors for later transplanting. If you’re starting outdoors, wait until the danger of frost has passed. In frost-free areas, you can sow seeds outdoors when temperatures consistently reach at least 55°F. Alternatively, consider sowing in the fall as temperatures start to cool in warmer regions.

Starting Seeds Indoors

When starting mint seeds indoors, it’s essential to use a sowing aid like a seed sower to prevent overcrowding of seeds. Begin by filling a plug tray with potting soil and carefully sow two to three seeds per cell on the surface of the medium. Place the tray on a heat mat and provide adequate sunlight or grow lights for germination. Be sure to transplant seedlings after they have developed at least two sets of true leaves.

Sowing in Containers

For indoor or patio cultivation, choosing containers with drainage holes is essential to prevent mint from taking over. Simply scatter seeds in a pot filled with potting soil, keep the soil moist, and thin out weaker seedlings as they grow.

Sowing Seeds Outdoors

After the last frost date, choose a sunny or partially shaded location with well-draining soil to sow mint seeds. Thin out seedlings as needed to maintain adequate spacing and improve air circulation.

Transplanting

Once seedlings are ready and have been hardened off, transplant them into a sunny location with ample sunlight per day. Water well and prune to encourage bushier growth. Watch for buds and pinch them off to prevent seeding.

A Word of Caution About Mint

Mint is a vigorous creeper that can quickly spread by rhizomes underground, so it’s essential to monitor its growth regularly. Consider planting mint in containers to prevent invasive growth.
