Fill a shallow container with good potting soil to ½ inch from the top. Use trays specifically made for growing microgreens, or upcycle takeout containers. Just be sure that the container you use has sufficient drainage.
Sprinkle seeds for microgreens densely on the soil surface. Cover loosely with a light layer of additional soil.
Use your hands to press the soil down firmly over the seeds.
Water the seeds in thoroughly.
Place the container on a tray to catch excess moisture and set in a spot where the tray will receive plenty of light. Without strong light microgreens will grow spindly and leggy.
Water gently when soil begins to dry out.
Notes
Microgreens can be grown in a sunny window if you live where there is adequate sunlight year round. If you live north of the 40th parallel, you’ll need supplemental light in the winter months to grow microgreens.
