What Are Microgreens?

The word “micro” here says it all. Microgreens are young seedlings of edible vegetables and herbs. Unlike larger herbs and vegetables that take weeks or months to grow, microgreens can be harvested and eaten a week to 10 days after the cotyledon — a part of the embryo within the seed — leaves have developed.

These tiny versions only grow to a few inches and can come in 50 to 60 different varieties. Microgreens were originally limited to fancy dinner plates and boutique grocery stores due to their higher cost.

After each harvest, growers need fresh soil, seed and a sterilized container or growing mat to repeat the growing process. These costs add up compared to mature herbs and vegetables that grow back after they’re initially cut or trimmed.

Benefits Of Microgreens

Despite their small stature, microgreens actually boast a more intense flavor than larger vegetables and herbs. One study even found they have more health benefits and can be up to 40 times more potent in phytochemicals.

The study, from 2012 by the Journal of Agricultural and Food Chemistry, analyzed 25 microgreens and, on average, determined microgreens have four to six times more nutrients than their mature counterparts. For example, red cabbage microgreens had 40 times more vitamin E and six times more vitamin C, while cilantro microgreens had three times more beta-carotene.

Among the microgreens assessed, red cabbage had the highest concentration of vitamin C, cilantro had the highest concentration of carotenoids (a type of antioxidant found in brightly colored foods), garnet amaranth had the highest concentration of phylloquinone (a type of vitamin K) and green daikon radish had the highest concentrations of tocopherols (a type of vitamin E).

While microgreens are nutrient-dense, they aren’t typically viewed as a substitute for regular vegetables due to the cost and volume you’d have to eat.

How to grow microgreens

As expensive as some microgreens are in grocery stores, you can easily grow them in your own kitchen or outside in a garden. All you need is light, a container, soil and water. Of course, you also need seeds to plant. Many stores or internet marketplaces sell pre-packaged seed mixes that have similar flavor profiles.

Some of the more popular seeds include the following plants:

Depending on the seed size, some may require a pre-soak in water before planting. Make sure to read the directions. Microgreens such as kale and pea have larger seeds, while arugula, basil and mustard are medium seeds. Herbs such as oregano, thyme, mint, tarragon and sage all have small seeds.

Growing microgreens outdoors

Once you have your seeds picked out, it’s now time to plant! If you’re planting the microgreens in an outdoor garden, break up the existing soil and smooth it with a rake.

Place the seeds ¼ -inch from each other and press gently into the soil with your hands. Cover with about ⅛ inch of soil. Take a spray bottle and mist the seeds so they’re damp, or until the soil feels like a sponge — not too wet but not too dry. Using a spray bottle will avoid dislodging the seeds.

Growing microgreens indoors

If you choose to plant your microgreens indoors, fill a small container with a few inches of organic potting mix. Plastic containers used for fruit, such as blueberries or strawberries, work well for this type of planting. Clamshell takeout containers will also work, as will aluminum pie trays — just be sure to poke some holes in the bottom so water can drain. Place a damp paper towel in first before the potting mix to prevent it from leaking out.

Using the same technique as you would for your outdoor microgreens, scatter the seeds ¼-inch apart and gently press them into the soil. Proceed to cover the seeds with ⅛ inch of potting mix. Mist the soil with enough water so it feels like a sponge.

Some growers recommend placing plastic wrap over the microgreens to promote germination. Place the microgreens on a south-side windowsill or another area of your house where it gets at least four hours of sunlight a day.

When to harvest microgreens

Moisten the soil as necessary and avoid overwatering. The microgreens should be ready to harvest in 10 days to two weeks once the true leaves (not the seed leaves) begin to sprout. Take a scissor and snip the microgreens slightly above the soil. Unfortunately, the microgreens won’t regrow after an initial harvest. To grow more, you will need new seed and soil.

For an easier solution to growing microgreens, you can also buy microgreen kits that take most of the work out for you. These kits generally include seed packets, compostable grow trays, soil discs and tray covers. All you do is water each day until the microgreens reach their desired length. Many big box stores, such as Lowe’s and Home Depot, now sell microgreen kits.
