Check out this Step by step growing amaranth microgreens guide:

Step 1 – Choose Your Growing Medium

To successfully grow amaranth microgreens you need to have a deep medium, 3-4 inches is a good starting point. This will give your roots room to grow and the soil will stay moist enough that you don’t need to water it too often.

You’ll need either a 10×20 tray or another container that suits the number of amaranth microgreens you’re hoping to grow.  It will also be important to decide your preferred growing medium. A 50% soil and 50% coconut coir is a great option, although clay can also be a good way of keeping the plants moist without drowning them.

It can also be a good idea to make sure that your tray has drainage holes in it. You can then place a water tray under the growing tray, allowing the soil and plants to absorb water as they need it.

Step 2 – Preparing Your Seeds

It’s a good idea to use a seed shaker but you can do it by hand if you prefer. You’ll need to lightly cover the top of your growing medium. They should not be so dense that you can’t see any soil but you also don’t need to much soil still showing!

Step 3 – Germinating

Once you’ve planted the seeds slightly mist them with water. Don’t put too much on, you’ll increase the chances of mold growing.

You should then cover the tray with another tray; you don’t want the light to get in but a couple of ventilation holes on the sides will help to reduce the risk of mold growth.

For the next 2-3 days lightly mist the seeds once a day; you should see signs of germination by the end of this period.

Step 4 – Letting Them Grow

Once they have germinated you can leave the cover on for an extra 24 hours, this will help them grow a light pink color.

However, as soon as they reach ½ inch tall it’s time to remove the cover and transfer them to the light.

They don’t actually need direct sunlight, this is likely to kill them. During this time you should mist the plants daily or ensure there is always water in the tray below the growing media.

Once they hit 10 days old they should be ready to harvest!

How to harvest amaranth microgreens

Once your amaranth microgreens appear to be ready use a sharp knife or scissors and cut the stems just above the soil line. This will prevent the soil from contaminating your plants; ensuring they don’t need to be washed.

Washing them can damage them as they are very delicate at this age.

Once dry, simply place them into a plastic bag or container and store them in your refrigerator. They will only last 5-7 days and do taste better fresh. You may prefer to harvest them when you want to eat them.
