Days to Maturity: 10–15 days
Native: Widespread; probably Eurasia

When to Sow Outside: Not recommended. Microgreens are fragile, and outdoor growing conditions makes them difficult to clean.
When to Start Inside: RECOMMENDED. Sow indoors any time of year. For a continual crop, sow every 7 to 14 days.
Days to Emerge: 3–4 days
Seed Depth: ⅛”–¼”
Seed Spacing: ¼”–½”
Thinning: Not required
Harvesting: When seedlings emerge, the first pair of leaves to show are the cotyledons, which can look very different from the leaves that follow, called “true” leaves. Microgreens are ready to harvest when they have cotyledons, or when the first true leaves have begun to form, depending on preference. Cool growing temperatures may slow the expected amount of days to maturity. Using scissors, cut microgreens just above the soil line when you are ready to use them.
