How to Grow Corn Microgreens?

Corn microgreens, also known as Corn sprouts as they can be harvested just after they sprout, became popular among vegetarians and healthy eaters in the mid-1990s. Ever since then, cultivating them has become a common practice among home gardeners across the world.

To grow your own young, healthy, and tasty corn microgreens, you would first have to choose and prepare your seeds before you start off with the process.


The first thing to do to start the process of growing your corn microgreens is to soak the seeds in water to facilitate germination. Unless you have soaked your seeds enough, the hard shells would not soften, air circulation would not take place, and eventually, your seeds would not germinate after being planted.

You would not be seeing the seeds sprout like in the case of wheatgrass and some other microgreens, but soaking them for about 8 to 12 hours is mandatory to make sure all your seeds sprout in the soil. Keeping the seeds in an open region where proper air circulation is good should help the seeds.

Sowing the seeds

After your corn seeds have soaked well, they are ready to be planted. For this, first, you have to prepare the soil. Corn microgreens do well in potting mix or gardening soils. Take a shallow, flat container, like a tray, and fill it up with about 1.5 to 2 inches of the mix.

Next, wet the surface with water. Be sure not to overwater the soil as corn microgreens do not grow well in puddles of water. Make sure your container has drainage holes. In case it doesn’t, make holes in it in a way that allows excess water to drain out of the bottom.

Spread the soaked seeds on the soil. The seeds can be close together, but do not pile them one on the other. The surface of the soil should be wet enough for the seeds to stick to it. Make sure that the seeds have good contact with the soil and cover the tray with another tray.

Take extra care to keep the tray covered, and preferably keep it in a dark but warm place for germinating. Do not expose the germinating seeds of corn to direct sunlight at any cost.

In case of exposure to the sun, your corn sprouts would start the process of photosynthesis, and develop sturdy, tough, and fibrous shoots. Soon, they would turn green, acquiring a bitter taste, and take the form of corn husks.

The target is to prevent them from turning green. When left in darkness, away from direct sunlight, the microgreens would remain yellow, with a tender, crunchy texture and a slightly sweet, delicious taste. Corn microgreens take about 2-3 days for germinating.

Use a spray bottle to water your corn microgreens about once a day, every day until the young sprouts have firmly established their roots in the soil. However, avoid overwatering. If the soil is too wet and water reaches the seeds, mould might develop on them, after which the microgreens would die.

If possible, add another tray full of water under the tray with the seeds. Make holes in the upper tray so that the roots from the seeds can access the water source to fulfil their needs. Clean the water tray regularly to keep the plants healthy.

While watering, you can uncover the plants but be sure to cover them up again, putting the lid in place to prevent the plants from getting any direct sunlight. The plants would have to be watered, and their growth would have to be monitored for the next five to nine days during which your plants would grow.


Your corn microgreens would be ready to be harvested when the sprouts are about 2-4 inches tall. You can harvest them according to your taste preference and need once they have attained the proper size.

The taste of the microgreens would keep changing a little every day, and to find out the perfect taste for you, cut a small portion everyday and taste. Make sure you cut microgreens as close as possible to the soil.

To store your microgreens, place them in a plastic bag and refrigerate. Make sure to store them dry as moisture would cause mould to develop, and might even result in rotting. Wash them as and when you use them to make sure they stay fresh for the longest time possible. If stored properly, they can stay fresh for about two weeks.

Growing microgreens at home can be a fun experience, with the added bonus of a delicious and healthy variation on your table. If you are a lover of corn and sweet corn and enjoy their delightful taste during summers, growing them as microgreens would bring you the opportunity to enjoy them all year round, as and when you please.
