Growing peppermint

 To sow the seeds indoors, place them on top of the Bio Sponge in your Bio Dome, or on top of the medium in your seed flat. Do not cover the seeds with potting mix!!!; they need light to germinate. They should sprout within 14 to 21 days at room temperature or slightly warmer (68 to 75°F). Transplant into the garden or container when they have at least 2 sets of true leaves.

To sow the seeds outdoors, place them on top of well-worked soil, then sprinkle a fine layer of vermiculite on top of them. If you are sowing directly into the garden, consider placing a row cover over the seeds until they sprout.

Mint thrives best in partial shade and rich, moist soil. However, it is famously unfussy, so chances are it will not only survive but flourish in any light from full sun to deep shade, and any quality of soil provided the drainage is decent. Many gardeners deliberately plant it in less favorable conditions to slow down its spread!
