When to Sow Outside: Not recommended. Microgreens are fragile, and outside soil makes them difficult to clean.

Days to Emerge: 5–8 days
Seed Depth: 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. Beet microgreens are ready to harvest 15 to 25 days after sowing, 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.
