While harvesting you should cut the stem above the soil line Microgreen contains fully developed cotyledon leaves and some partially developed to leaves.

  • Microgreen plants are consist of three basic parts
  • Central stem, Cotyledon leaf, true leaves

They vary in size according to the variety; the typical size of a microgreen plant is 1 to 1.5 inches. The plants which grow above the height are known as petite green. Microgreen plants can be harvested after 10-14 days from seeding. There are some slow growing microgreen varieties that take 16 to 25 days to get ready for harvesting such as beets, chard and various herbs. Generally, microgreens are consumed with entire plants including root, seed and shoots depending on the variety. There are two marketing terms used: “baby greens” and “microgreens”.          

Growing

Plants such as potatoes, tomatoes, eggplants and peppers should not be grown as microgreens because the sprouts of these plants are poisonous; they contain toxic alkaloids such as solanine and tropanes hence consuming these sprouts can cause adverse symptoms in digestive and nervous system.

According to USDA Agricultural Research Centre 25 varieties were tested and key nutrients were found are ascorbic acid (vitamin C) tocopherols (vitamin E), phylloquinone (vitamin K) and beta carotene (vitamin A). Red cabbage, cilantro, garnet amaranth and green daikon radish are some of the greens that contain the highest concentrations.

Microgreen contains 40 times more nutrition including vitamin C. K and E in comparison of fully grown leaves.

How to grow microgreens

Most varieties of microgreen crop grow within a week or two weeks but some varieties need time to get ready for harvest; they might take around 3-4 weeks. Harvesting of microgreens is done with scissors cutting them just above the soil surface. You can check cotyledons expansion before starting microgreen harvesting if cotyledons are expanded well then they are ready to harvest. It is seen that some microgreen growers sell microgreens while growing in trays to be cut later for fresh microgreen ingredients.

One of the major problems that people face; when the seed germinate they look for light when they don't get enough light the looks legi and eventually they become weaker and the fall on the soil this is basically the sign that your plant is looking for more light you cannot grow microgreens in low light condition so whenever you see symptoms like this shift them to direct sunlight these steps are applied to most of the microgreens Don't try to grow every kind of seeds as microgreens don't use potatoes as microgreen.
