Here’s your step by step guide for how to grow corn microgreens:

Step 1 – Soaking

It is essential to soak your seeds in water for around 12 hours before you plant them. You won’t see them sprouting at the end like wheatgrass does. Make sure there is air circulation in the sprouter and you don’t have a closed lid.

Top Tip: The seeds like air-circulation. Keep them in an open place where there is plenty of air flow. Prior to shoot growth, indirect sunlight is not an issue.

Step 2 – Planting

Corn microgreens actually grow very well in a potting mix (peat moss + vermiculite). It is important to note that corn microgreens are not happy in puddles of water. You should, therefore, make your soil approximately 1-2 inches deep. with drainage holes in the bottom.

Water the soil thoroughly and make sure there are no puddles of water before planting. You can put as many as 2 cups of seeds in a 10×20 tray, being packed together is not an issue for these plants.

Once planted the seeds need to be covered in the dark. Keeping them dark will ensure they have a yellow color, making them sweet like popcorn. Restaurants prefer sweet corn for microgreens and they are yellow instead of green.

Step 4 – Watering

Spray the plants once a day until their roots are established in the soil. Then you should only water the soil, not the plants (bottom watering – make sure the water is only touching the roots, not the seed kernels to prevent mold growth). If there is little soil visible then add water to the drip tray under the planting tray; this will allow them to access the water they need.

You’ll need to monitor them and water them daily for the next 5-9 days.

Bonus Tip: Keeping them covered will give you yellow stalks which are sweeter.

Once they reach between 2-4 inches tall they’ll be ready to harvest depending on your taste preference.
