Keep the soil consistently moist. Prevent soggy soil by pouring off any excess water that collects in the drip tray after watering. To harvest, snip the microgreens right above the soil line when their first true leaves unfurl (about 7 to 14 days after germination, depending on the green). The microgreens are nutrient-dense and make a healthy addition to salads and sandwiches.
