What happens if you let microgreens keep growing?
The plant will not be able to overcome that kind of stress to grow back. That is why microgreens don't grow back after you harvest them. But not cutting off the stem and leaves (leaving them growing in the tray) will also eventually cause them to have an extraordinary amount of stress causing them to die.
To harvest microgreens, you'll simply cut each baby stem above the soil line. Unlike with sprouts, you won't eat the entire plant, just the stems and leaves, because the roots will be covered in growing medium.
Microgreens are ready to eat immediately after they've been cut or harvested. But be sure to rinse them with filtered water before serving. Bacteria is an unlikely possibility because microgreens grow in an open-air environment and with soil, but it's better to give a quick rinse before serving than be sorry later.
Microgreens are basically many of the same leafy greens as are used for salad mixes but are cut at a smaller stage and only harvested once.
Eating microgreens is generally considered safe. Nevertheless, one concern is the risk of food poisoning. However, the potential for bacteria growth is much smaller in microgreens than in sprouts.
But do microgreens regrow after cutting? Unfortunately the answer is no, in most cases. All of the energy in a microgreen seed goes into producing those first few sets of leaves. So once you cut the microgreen, there's no energy left for it to grow back again.
As a general rule, purchased microgreens typically last 10-12 days in your fridge. If you were to grow your own microgreens and cut them at home, they would last about two weeks, on average.
One of the most common questions we receive is: "Can I reuse microgreen soil after harvesting?" Our answer has always been, "No, it's best to use new soil to reduce the possibility of disease. Plus, the new microgreens will grow better on fresh soil."
Microgreens rank among the simplest, smallest, and yet most nutritious and delicious plants you can grow in the garden. There are many rewarding aspects to starting these quick-growing plants for yourself, but perhaps the best thing about microgreens is how easy they are to grow at home.
The methods are the Weighted Blackout Method and the Domed Blackout method. The two trays on the bottom use the weighted method, the weights and upper tray are pushing the seeds into the soil. This makes for better seed to soil contact and usually better germination and more vigorous, sturdier microgreens.
Can you survive off microgreens?
Q: Can you survive on just microgreens? A: Microgreens are packed full of vitamins and minerals. Compared to fully grown crops, they contain 4 to 40 times the nutrients. But I wouldn't recommend a diet that exclusively consists of microgreens.
Tasty foods can make you overeat. So, you should be aware that some vitamins and minerals have a maximum daily dose to prevent bad effects like nausea and diarrhea. However, you would have to eat 20-plus pounds of microgreens a day for a week to reach levels that could cause you any potential life-threatening harm.
Pea shoots are one of the healthiest types of microgreens, which is why we like to include them in our Seasonal Microgreens Seed Club from time to time. Pea shoots contain beta-carotene – which our bodies convert into vitamin A, vitamin C, folate–essential building blocks for the human body, and fiber.
You should rinse your microgreens. Yes, I know it is easier to just eat out of the package (or right out of the living tray), but your really do want to rinse them off anyway.
Microgreens are edible plants harvested when they are young and small, at about 1.5 to 3 inches tall.

You've probably seen plenty of claims about how much money you can make growing microgreens. Yet one of the most common questions people still ask is: “Are microgreens profitable”? The short answer to this question is: Maybe.
Microgreens are clearly more nutrient dense, meaning typically they are more concentrated sources of vitamins and minerals. And like the full sized versions, microgreens are equally low in energy (about 120kJ or 29kcal per 100g based on US data).
Additionally, sprouts are better sources of amino acids, pectins and sugars than microgreens. Microgreens were characterized by high content of carotenoids and chlorophylls, and organic acid, without any sugars, exhibiting higher anti-diabetic and anti-cholinergic activity than sprouts.
Radishes are the fastest growing microgreens and should be harvested before their first true leaves develop. A family shouldn't have any problem using up a Home Microgreen Tray full of radish microgreens before they need to harvest and store them in the refrigerator.
Microgreen seeds are no different from regular seeds. They are the same varieties grown in the garden or found in the produce section of the grocery store. So you don't need special seeds for microgreens.
What do you do with microgreen roots after harvest?
When using a reusable grow medium, you want to try and remove the left-over microgreens & roots. If you're using a mesh screen then you simply remove the harvested Microgreens leftovers and compost them afterwards. You can do this by pulling them out or scraping the remains into a compost bucket with your hands.
Microgreens definitely need to be refrigerated. Just like lettuce and other leafy greens, microgreens need to be kept cool to extend their freshness.
STORAGE: Dry the sprouts and store in an air-tight container in the fridge. If there is excess moisture, the sprouts may become moldy. Use quart-sized mason jars - as the seeds sprout, they take up 2-3 times the original amount of space in the jar.
As a general rule, 12-18 hours of artificial light is sufficient for microgreens' best growth. Under natural light, it is best to give them 5-8 hours of sunlight under shade to prevent scorching. However, different seeds will have varying growth rates even if they receive the same amount of light.
Also, if you're like us and cringe to waste anything (especially a seed!), here is some great news: growing microgreens is an easy way to use old seed without letting them go to waste. Even as germination rates may drop as seeds age, microgreens are sown so densely that it generally works out brilliantly.
It should preferably be soil-less. A peat based mix (either coco peat or peat moss) with vermiculite and perlite works best. Commercial garden soil varieties are not the best medium for microgreens because they are too compact and don't allow the roots to penetrate and grow.
Soil. Soil is the tried and tested way of growing microgreens. Any organic potting soil will work best, but a favorite among many US-based microgreens growers is Happy Frog potting soil by Smart Naturals, which is available at most Walmart stores and lots of garden centers across North America.
Sprouted seeds and microgreens are often more nutrient-dense than ungerminated seeds or mature vegetables.
If your climate is suitable, microgreens can be also be grown outdoors in the garden, under shade. Like all fragile seedlings, you'll need to protect them from weather extremes and drying winds, not to mention hungry garden pests.
You open the lid and are dismayed to see white fuzz growing on the roots – what the fluff, is this mould!? No, this is a common misconception, and the white fluff that you see are actually tiny microgreen root hairs and they are completely normal (and beneficial) to the microgreen growing process.
Do microgreens attract bugs?
There are few microgreen pests to worry about. Because microgreens are usually grown inside the house and they have a short life span there isn't much contact or time for infestation. The three most common pests are aphids, whiteflies, and fungus gnats.
The microgreen growing process is quite labor intensive, what with keeping the greens sufficiently hydrated, nourished, and well-lit. This is why, in the grocery store, you will see microgreens priced higher than full size vegetables.
All microgreens excel when eaten raw. Skipping the stovetop not only keeps them fresh and crisp, it also preserves the delicate flavor profile you expect from each of these mini powerhouses.
The five most flavorful microgreens to try growing are mustard, pea, beet, garden cress, and radish.
In addition, they can contaminate food with their feces, containing harmful bacteria such as E. coli and salmonella. Microgreens need to be thoroughly washed before they're served.
Researchers say buckwheat microgreens are good to eat but don't consume more than 40-grams per day. This is a reminder that eating a lot of one thing is most likely not as good as adding a variety of greens to your diet.
Both in vitro and in vivo studies have shown that microgreens have anti-inflammatory, anti-cancer, anti-bacterial, and anti-hyperglycemia properties, making it a new functional food beneficial to human health.
Pre-freeze the microgreens for about 30 minutes or an hour by placing them on a parchment paper or a tray. Avoid overlapping them if possible, as this will prevent them from sticking together. After an hour, remove them and preserve the dry microgreens in an airtight freezer bag or container.
If you wait too long to harvest, they will start to yellow or have stunted growth. Signs of plant stress can happen from several factors such as soil quality, plant species, and more. This is why it's best to harvest your microgreens when the cotyledons or true leaves appear.
Microgreens are ready to harvest usually two to three weeks after planting, making them a very quick crop for gardeners. Harvest when you see the first set of real leaves. Once leaves appear, snip the microgreens just above the soil line. Serve immediately for the best flavor.
Can you let microgreens go to seed?
You can't harvest seeds from microgreens. Microgreens are vegetables, herbs, and flowers gathered two to four weeks after sprouting. To grow more microgreens, you will need to harvest seeds from a mature plant.
As a general rule, purchased microgreens typically last 10-12 days in your fridge. If you were to grow your own microgreens and cut them at home, they would last about two weeks, on average.
One of the most common questions we receive is: "Can I reuse microgreen soil after harvesting?" Our answer has always been, "No, it's best to use new soil to reduce the possibility of disease. Plus, the new microgreens will grow better on fresh soil."

YES! You can eat microgreens and they're super beneficial… however… The growing environment for sprouts is the most optimal environment for bacteria such as listeria and e coli to grow.
