What are Microgreens?
Microgreens are ordinary vegetables that are simply harvested when they are young seedlings. True to their name, they鈥檙e harvested when 鈥渕icro鈥 or about 2 inches tall鈥攁s soon as the first leaves (called 鈥渃otyledons鈥) appear.
include salads, herbs (basil, parsley, chives, cilantro), beet greens, radish greens, turnip greens, kale, arugula, chard, peas, watercress, and bok choy.
How Long Does it Take to Grow?
Most microgreens germinate in 2 to 3 days. They can be harvested in 1 to 2 weeks!
Most often, microgreens are grown at home on a sunny kitchen windowsill. They鈥檙e delicate and grow quickly, so it鈥檚 not worth exposing these tiny babies to the elements of outdoor weather.
Note: Microgreens are different than bean sprouts. Sprouts are harvested earlier before true leaves have begun to emerge. They鈥檙e often grown without soil. Not sure which one to grow? Our gardeners tested microgreens versus sprouts!
Why Grow Microgreens at Home?

What You Will Need
If simply growing in the home for your family, they do not require typical gardening equipment.
Seeds
A flat growing tray or seed tray. You could also recycle any type of shallow container without growing holes.
Potting soil (not garden soil). Peat-based mixes from the garden nursery are popular, but there are also peat alternatives, including coconut coir. We personally love the growing mats; they combat mold and fungal growth as your microgreens sprout.
Place trays on a sunny windowsill, balcony, or small porch; if you wish to grow year-round, it鈥檚 worth investing in some energy-efficient LED grow lights.
Fill the trays with a couple of cups of water. Then add all-purpose potting soil within half an inch from the top of the tray. (Even better, just use a growing mat.)
Tamp it all down with something flat-bottomed, such as a wood block.
Broadcast sow your seeds, crisscrossing back and forth across the surface of the potting mix. Try to avoid any clumps and avoid burying the seeds.
Then, tamp the seeds gently down so they are in good contact with the potting mix.
Water your seeds by spraying them gently with a spray or mister.
Place the seeds in a warm, dark place to germinate for 2 to 3 days (warmer than 60掳F)
Apply gentle pressure to the seeds by stacking the trays two or three deep, then place an empty tray on top and weigh it down. This encourages thicker stems and stronger growth.
Growing
As soon as seeds germinate, transfer seed flats to a well-lit area, like a windowsill that gets indirect sunlight or grow lights. The more light, the faster they grow.
Leave grow lights on for between 12 and 16 hours a day. Put the lights on a timer, or alternatively, just switch them on when you get up and off when you go to bed.
Check the moisture of the potting mix daily. If necessary, mist with fresh water, but don鈥檛 over water as this can lead to mold growth.
To limit the contact between water and the greens, it’s best to water the trays from the bottom.
Types
While microgreens are easy to grow and super-quick, some seeds are better for beginners. If you’re just getting started, try radishes, mustard, greens, and kale.
Many online nurseries (such as ) also sell 鈥渕icrogreen mixes鈥 with various veggies, such as beet greens, kale, mustards, radishes, arugula, cabbage, and pac choi, as well as herbs.
None of these microgreen seeds require any special treatment such as soaking, etc.
Harvesting
Harvest your microgreens when they鈥檙e about 1 to 3 inches tall and have produced their first adult leaves. Use scissors to snip them off close to the bottom of the stem.
Microgreens are best enjoyed as soon as possible, but they can be kept in plastic bags in the salad compartment of your refrigerator for up to 5 days. Serve them in a salad or main meal or as a garnish.
To serve, wash them with water and dry them with paper towels or a salad spinner. Harvest and serve them immediately for the freshest flavor. Enjoy!

Pests/Diseases
Mold is the most common problem. It will appear as white, grey, or black fuzz and causing the microgreens to die. It’s a humidity issue that requires that you increase air circulation. Try adding fans or a dehumidifier.
Damping off is caused by a soil-borne fungi. Avoid overcrowding seed in a tray. Be sure to sow evenly.
Cooking Notes
Microgreens can be used as a salad green or as a side dish, similar to kale or spinach.
Sprinkle on sandwiches or avocado toast. Mix into smoothies or juices. Add to stir-fries, pasta dishes, veggie bowls, omelets, or any dish for added crunch and nutrition.
