Sow directly in late fall or spring after last frost. Direct seed germination in spring can take 2-3 weeks in cooler soil. Small plants require weed-free sterile soil. Thrives in cold weather and cool winter greenhouses and rich soil. Natural seed usually germinates in the fall. The germination of the smaller seeds from the perennial species is more dependent on temperature than the larger seeds from the annual species. The highest rate is between 65–75˚F day and 40–50˚F evening temps. Can tend to biannual. For micro greens, space 3-6” within row. Seeds require light to germinate, press into soil, do not cover. Soil pH 6.1-7.8. Hardiness zones 5b. Perennial.
Usual seed life 4–5 years.
