Spearmint Germination Information

Spearmint Seed Germination How to Sow Spearmint:
  • Best sown indoors at alternating temperatures of 55 and 72°
  • Sow with NO cover as light aids in germination
  • Seeds can also be sown outdoors in situ when the soil is cool in the spring or fall
  • Sow with barely any cover
  • Indoors and out, expect germination in 15-20 days
  • The seeds are very small
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Spearmint:
Transplanting: Transplant when there are at least two sets of true leaves

Spacing: Space 18-24 inches apart

Lighting: Site in full sun

Soil: Site in rich, well-drained soil kept evenly moist

Additional Care: As plants vigorously spread underground via runners, plant them in submerged containers or in areas bordered by walkways or edging. Pinch to encourage branching and sheer plants after flowering to prevent seed formation. For indoor culture, it is best to start new plants from seed rather than potting up clumps from the garden

Appearance and Use:

This plant grows 18-24 inches tall and spreads indefinitely. The small, tubular, pink, lilac, or white flowers are not showy, but they attract bees. Grown for its bright green, aromatic, edible leaves. Harvest them at any time for fresh use; to dry them, harvest just before the flowers open. The leaves are used to flavor many concoctions: tabbouleh, mint jelly, mint sauce, desserts, and they flavor many drinks from mint juleps, mojitos, to iced tea. The essential oil is used to flavor candies and gum
