Spinach Microgreens
Spinach Microgreens: 25 days to harvest, 3-7 days to germinate, Dense seeding, no spacing needed between plants, pH 6.5-7.5, hardy in zones 2-11. Fruit runs to about 2-3 inch tall with first true leaves beginning. Give it full sun to partial shade (4-6+ hours) and bottom watering preferred, keep soil moist but not soggy water. It will crop in a container. Because this is a hybrid, seed saved from it will not repeat the parent — plan on fresh seed each year.
