Microgreens: Tasty Accents from Small Spaces

My first response to microgreens was: “Why would I spend my time growing 3-inch tall plants to eat?”

Then I thought about all of the tiny leafy green plants (beet, lettuce, kale, basil, etc.) I had eaten over the years in the process of growing transplants at home and in greenhouses. And it started to make more sense: why not plant seeds closely in a container to just grow baby plants?

Benefits: When you eat microgreens you are ingesting the cotyledons, stems, and small expanded true leaves of edible plants. Some reasons to give them a try:

Microgreens don’t constitute a meal; they add pizazz to a meal! Use them fresh in wraps, paninis and sandwiches, soups, omelets, and frittatas; sprinkled on green salads and vegetable salads, burgers, pestos, nutritional smoothies; as garnishes for grain and pulse dishes and cocktails, or chopped in dips; and eat them raw by themselves.

Getting started: Growing microgreens really is very similar to starting seeds to produce flower, herb, and vegetable transplants. Two plant families are especially well-suited: Amaranthaceae (e.g., beet, Swiss chard, leafy amaranth, magenta spreen) and Brassicaceae (e.g., kale, cabbage, radish, mustard, arugula, mizuna, komatsuna, Tokyo bekana). Best not to mix the two families because of varying germination and growth rates.

Cilantro and basil (both slower growing), pea shoots, onion, and lots of other plant species have been grown for microgreens. Soaking Amaranthaceae seed and cilantro seed in water for 12-24 hrs. speeds germination.

What Do I Need?



Light (16 hrs. under a shop light) and heat (70-75⁰ F.) are needed for quick germination and growth.

How do I grow them?


Roots watered from the bottom when shallow grow tray is inserted into deeper tray without holes.

Does it pay for itself?

If you select reusable containers, buy non-hybrid seeds by the ounce and growing media in large bags, you can grow your own microgreens for about 1/2 of the supermarket price!
