Beet microgreens are a colorful, earthy tray crop with red stems and a mild beet flavor. They take longer than most microgreens and germinate unevenly, so they suit growers with a little patience.
About Beet Microgreens
Beet microgreens (Beta vulgaris) are a colorful, earthy tray crop with deep-red stems and green leaves and a mild beet flavor. Beets trace back to the Mediterranean and Near East, and at the microgreen stage they bring striking color to a plate. The tray itself is small, a shallow 2-litre container in moderate light, so the space cost for a renter is low even though this crop takes longer than most microgreens.
These are rated moderate mainly because germination is slow and uneven. Each "seed" is really a corky cluster of several, so soak them 8 to 12 hours before sowing to help them along, and expect patchy sprouting. Moderate light is enough, and good light once they're up deepens the red stem color. They take longer than brassica or radish trays, usually around 14 to 21 days to harvest.
What it’s like to grow
Beet microgreens are the most patience-testing tray in this group, though not difficult once you accept the timeline. Germination is patchy and slow compared with faster microgreens, since each husk holds several seeds, and the corky husks can grow mold if kept too wet. Soak before sowing, water carefully, and give good light once up to bring out the red stems. They want only moderate light overall. Non-toxic to cats and dogs, they're for a grower with a little patience who wants color and an earthy flavor.
What to expect
First harvest in about 14–21 days. It asks for a little consistency, but nothing fancy. No sunny window? It also does fine under a clip-on grow light.
