How to Grow Microgreens: A Growing Guide

Growing microgreens is the perfect activity if you are getting the gardening itch or just want a little extra antioxidant boost (source). It’s an easy way to maintain access to fresh greens even when outdoor gardening isn’t feasible because of snow and cold, or if you’re short on gardening space.

From start to finish, microgreens only take 8-14 days to harvest so you won’t have to wait very long to be tasting your very own! These tiny powerhouse plant starts are quick and easy to grow, require minimal supplies, and thrive in small spaces.

Let me show you how to grow microgreens on your countertop (or table). You’ll be growing these little beauties on repeat all year long.

What Are Microgreens?

Microgreens are young sprouts (of regular plants) that are harvested at an early stage of their growth, pretty quickly after they have germinated. These edible greens are then snipped after they develop their first set of true leaves and can be used as a garnish, added to salads, or eaten on their own.

Microgreens are known for their big flavor and bright color. They also pack a nutrient punch, often having a higher vitamin content (Vitamins K, C, A, and E) than their full-grown siblings (source)!

Microgreens can be eaten raw or cooked and are perfect for salads, sandwiches, and smoothies. We even like to eat them by the handful!

Common Types of Microgreens

Cilantro: mild version of its big brother
Sunflower: mild, nutty
Radish: spicy and peppery
Peas: sweet and crunchy
Broccoli: earthy and slightly sweet (we call it “light broccoli”)
Salad Mix: mild peppery taste
Spinach: mild and sweet

Benefits of Growing Microgreens in Winter?

Winter can be challenging to find fresh produce that doesn’t cost a lot, especially if you are looking for organic. And with cold weather and limited sun, most of us in the Midwest aren’t able to grow a garden outside from November to March. Growing microgreens inside offers you that fresh pop of green and a burst of nutrients at a low price.

It only takes a packet of seeds, some soil, and light, and you will be on your way to a supply of fresh and nutritious greens.

Essential Supplies for Growing Microgreens Indoors

1. Seeds

You can buy seeds specifically labeled for microgreens, but it is not necessary. Microgreens can be grown from most standard seeds, although some seeds may be more recommended and packets labeled for microgreens may come with more seeds.

If you buy regular seed packets you may have to purchase a few to get enough seeds. Make sure you purchase untreated seeds. Our favorite microgreens to grow are from Barefoot Microgreens.

2. Containers

You will want to get some shallow trays or containers with drainage holes. Recycled items like plastic containers or Tupperware can also be used, as long as there’s drainage.

3. Soil

Microgreens can be grown in a variety of mediums, but we generally prefer to use soil as that gives the best flavor. An organic potting mix will work just fine!

4. Light

We like to place our microgreen trays on a table or cart near a south-facing window. If it is winter or you don’t have space near a window and sunlight is limited you can purchase grow lights to provide your microgreens with light.

5. Small Watering Can

When first planting the microgreen seeds you’ll just need to sprinkle or spray a bit of water to keep the soil damp, but once you expose the sprouts to light you will need to water them every day from the bottom. You can use a mini watering can or even just a water bottle or cup.

Step-by-Step Guide to Growing Microgreens

Growing your own microgreens is simple and rewarding. Follow our step-by-step guide to give yourself a bountiful harvest.

Below is the schedule that typically works for us when we grow broccoli and salad microgreens, but the length depends on the seed type. Take a look at your seed packet(s) and it will tell you how many days it takes to germinate. Use that as a reference for when to uncover your microgreen sprouts and keep an eye out for the first true set of leaves before harvesting.

DAY 1: Prepping Microgreens

Step 1: Find Some Space

Select a spot on your countertop or a table that maintains a consistent temperature, and it’s a bonus if this space has natural light. Near a south-facing window is best.

Step 2: Prep Your Growing Container

Choose shallow container that is approx. 1–2 inches deep. Make sure there are drainage holes to prevent soggy and rotting roots. Add a layer of soil about 1 inch deep and spread it evenly across the container.

Step 3: Adding the Seeds

You will want to sprinkle your seeds evenly across the soil, trying not to have big piles.

You can lightly press the seeds into the soil or you can sprinkle a “dusting” of soil over the top of the seeds.

Spray or dribble all of the seeds lightly with water. You can use a spray bottle, or just drop water with your hands over the seeds. You want to make sure the soil and seeds are moist but you do not want to soak them.

Cover your container with a tray or lid to keep the seeds in the dark and to retain moisture while they germinate. You want the darkness to mimic being planted outside in the soil.

DAYS 1-3: Germinating Seeds

Keep microgreens covered for about 3 days, occasionally checking to make sure they are not drying out. If you need to you can mist them with a bit more water to keep them damp.

DAY 4: Let Them Have Light

On day 4, or once your seeds have germinated, you will want to uncover your microgreens and expose them to light. This can be from the south-facing window or from LED grow lights.

DAYS 5-9: Growing Microgreens

Every day you will want to water (from the bottom) your microgreens with about 1/2-1 cup water per tray. Try not to overwater them as you do not want the roots to get soggy or start to rot.

I also like to turn my trays 180 degrees when I water as the seedlings will lean toward the window and I want them to get even exposure.

DAY 10-14: Harvesting Microgreens

Harvest your microgreens! Your microgreens are ready to harvest when they have developed their first set of true leaves and are about 2-3″ tall.

Cut your microgreens with a clean sharp knife or scissors. Make sure to cut them straight across and not at an angle, and as close to the soil as you can. Don’t worry about perfection though!

You can choose to just harvest part of your tray every couple of days to maintain freshness.

You may get lucky and get a late bloomer round of microgreens after your initial harvest, but I generally do not wait for those. I will compost my used soil and then start with fresh soil when I am ready to grow more microgreens.

Storing Microgreens

Place freshly cut microgreens in a well-ventilated and dry container like a plastic berry container or a container lined with a paper towel.

You can store them in the fridge for up to about a week if they are stored properly. They must be kept dry!

If you choose to wash your microgreens after harvesting, quickly run under cold water, then pat them very dry before storing to avoid molding and wilting. Check your microgreens regularly to remove anything that has wilted.

I hope you’ll try growing and harvesting your own microgreens so you can enjoy fresh, flavorful greens any time you want!
