Micro-greens may be tiny, but they’ve become a huge trend found everywhere from corner bistros to plastic-wrapped at the grocery store. And if you’ve taken a look at the prices, they are not cheap! The good news is that it’s easy to grow your very own organic micro greens, indoors or out.

What Are Organic Micro-greens?

Micro-greens are simply greens, lettuces, and herbs that are harvested when they are quite young — generally when they are approximately an inch tall, growing them organically is just the method that’s healthiest for you.

What Can You Grow as a Micro-green?

Basically, you can grow any lettuce, salad green, or herb as a micro-green. It’s easy to start with a pre-packaged organic seed mix, and you can look for specific micro-green mixes. Here are a few popular varieties to grow as micro-greens:

  • Mustard
  • Kale
  • Endive
  • Arugula
  • Beet greens
  • Spinach
  • Tatsoi
  • Radish greens
  • Watercress
  • Mizuna
  • Peas
  • Cabbage
  • Basil
  • Lettuce(any)

How To Grow Micro-greens

Micro-greens are very easy to grow. You can grow them outside, in a garden bed or in containers, or inside on a sunny windowsill.

If you are planting micro-greens in a garden bed, loosen the soil and rake it smooth. Scatter your seed mix so that the seeds are about 1/8 to 1/4 inch apart — remember, we’re harvesting them very young, so they don’t need a lot of room. Once the seed is scattered over the area, cover it with about 1/8 of an inch of soil and water gently but thoroughly.

If you’re planting in a container, the first step is to choose a container that is at least two inches deep and as large in diameter as you want. Fill it with a good quality organic potting mix, and smooth the soil. Scatter the seeds so that they are about 1/8 to 1/4 inch apart, and cover with 1/8 inch of soil. Water gently but thoroughly, an place your container in a spot where it will get at least four hours of sunlight. If you’re growing them indoors, a south-facing window is best, but an eastern or western-facing one will do as well.

In either case, do not let the soil dry out, and be sure to remove any weeds so that the tiny greens don’t have to compete with them for water and nutrients.  If you’ve got plenty of organic matter in your garden bed, that will provide the perfect amount of nutrients. For containers, mixing in a bit of granular organic fertilizer to the soil before you plant will work fine, especially if you plan on using the same soil for several plantings of greens (more on this below.) Micro-greens grow for such a short period of time that they are rarely bothered by pests and diseases. However, if you are growing brassicas in your mix (mustard, kale, etc.) and cabbage worms are a problem, you may want to cover your micro-greens with a floating row cover to protect them.

Harvesting Micro-greens

The best time to harvest micro-greens is when they’ve developed their first set of true leaves (the first ones are seed leaves, and don’t look anything like the actual leaves of the plant), which is generally about ten days to two weeks after planting. To harvest, simply snip the micro-greens just above soil level.

Unlike baby greens, you won’t be able to get additional harvests from one planting of micro-greens. Because the plants haven’t had much time to develop, and you’re snipping off everything except the very bottom of the stem, the plant has no way to generate new growth. You can plant another crop after harvest by simply scattering fresh seed and covering it with soil. You don’t need to remove the old roots; they are good sources of organic matter.

As you can see, micro-greens are simple to grow, and provide you with a quick harvest for not much work. You can add them to salads, sandwiches, or stir-fries, and it’s much cheaper to grow your own than it is to purchase them. Experiment with different mixes, adding the varieties you like best. They’re definitely deserving of a spot in your garden.
