How to Grow Arugula Microgreens

Arugula microgreens are tiny leafy vegetables that you can increase in your home any time of the year. Therefore, they are a rich source of vitamins and other minerals and are used as garnishes or ingredients for different dishes.

More often, people confuse or use the same name to describe both the arugula microgreens and sprouts. They grow from the same seed but at different stages, and they taste differently. Arugula is more nutritious compared to sprouts making it the most expensive too.

 The arugula microgreens are easy to grow in that they need few essential items such as the sun and water, pizza, soups, or a salad. Growing arugula microgreens is super simple.

How to Grow Arugula Microgreens

For you to harvest highly nutritious Arugula, you will need suitable Materials. However, it’s up to you to make it complex if you wish by growing it without soil (hydroponics). So basically, all you need to grow your Arugula is these materials.

  • Containers such as 10×20 plant growing trays
  • Potting soil, a balanced mix of coconut coir and soil, would be great
  • Light
  • Arugula Seeds
  • Spray bottle for misting your plants

Planting                                                            

After you have collected all the materials you need, it’s time to plant. As you prepare to plant your Arugula, ensure that the surface of your growing media is flat, smooth, moistened and that you have the right kind of seeds.  

For example, if you are using a 10×20 plant propagation tray, 30ml of arugula seed will be sufficient. With such a space, you will have an adequate distribution of your seeds on the surface. If you are not using the propagating tray, use 2 inches of soil or growing media, especially if you intend to grow your microgreen past eight to nine days.

Cover your container with something that will block out all the light. Complete blocking of light provides your seeds with an ideal germination environment.  

Germination Time and Requirements

If planted appropriately, the arugula plant will germinate in three days. Ensure that you mist your seeds once or twice a day using the spray bottle to avoid drying the soil, which may lead to wilting. Continue keeping your soil or medium moist even after germination of the seeds. Note that if your medium is more profound, then you won’t need to water your plants frequently. It may take up to nine days before you water again.

Sometimes overwatering your Arugula can cause them to have molds. But this should not be confused with overgrown roots. The hundreds of tiny roots look like molds. The only difference is that they are evenly distributed and cluster around the taproot of your arugula plant.

Your microgreens will be ready for light after four to five days. Uncover them and put them in a well-lit area, but you will have to water them more if you decide to leave them outside.  If you move them indoors, then the number of watering sessions doesn’t have to be increased because the plants will not be subjected to intense sunlight.

When to Harvest

After planting and watering, your arugula microgreens should be ready for harvesting between 7 to 14 days. Also, when your microgreens are two-inch inches tall and the leaves are bright and open, it’s time to harvest.

Using a sharp knife or scissors, cut your Arugula at 1/4″-1/2″ above the soil to avoid the stress of washing them and cutting them excess dirt or seed husks. Store your arugula well in a dry place and ensure that they are dry if you washed them. If stored well, then you will get to enjoy them for seven days before they wilt.
