Microgreens: The Superfood You Can Grow at Home

Indoor gardening is satisfying, healthy, and great for beginners, too.

Microgreens are young plants that are harvested just a few weeks after germination. They are smaller than baby greens but larger than sprouts, and are often used as a garnish or in salads, smoothies, and sandwiches. Microgreens come in a variety of colors and flavors. Seeds that are often grown as microgreens include romaine lettuce, beets, and radish.

Are Microgreens Better for Me?

Studies have shown that microgreens are not only delicious, but also highly nutritious. In fact, they can contain up to 40 times more vitamins and minerals than their fully grown counterparts! They are also rich in antioxidants, which can help protect against chronic diseases such as cancer and heart disease.

What Seeds are Good for Microgreens?

There are so many varieties to choose from. It’s fun to rotate through the list to find your favorites. But if you know you like the flavor of basil, you’ll like it as a microgreen, too.

Our favorites include snap pea, cilantro, spinach, beet, romaine, radish, pepper cress, and coriander.


How to Grow Microgreens

It’s easy to get started, you just need a few basic supplies:

Seeds: Choose high-quality, organic microgreens seeds from a reputable online supplier like Park Seed. With so much variety, you'll find just what you need from organic to bulk microgreen seeds, and all conveniently availabe to order online for home delivery.

Soil: Use a high-quality seed sprouting soil or a soilless growing medium such as Espoma Seed Starting Mix or coconut coir.

Containers: You can use anything from seed trays to plastic containers with drainage holes.

Light: Microgreens need plenty of light, so either place them near a sunny window or use grow lights.

Water: Water your microgreens regularly, keeping the soil moist but not waterlogged.

Steps to Grow Microgreens

Step 1: Prepare the Growing Medium

  1. Open the bag of Espoma Seed Starting Mix and moisten the soil mix.
  2. Fill the Perma-Nest Plant Tray with the moistened Seed Starting Mix to about 1/4 inch below the rim.
  3. Very gently tamp down the mix to create a level surface.

Step 2: Sow the Seeds

  1. Sprinkle the seeds evenly along the top of the soil.
  2. You can mix seed types or sow them separately.
  3. For the small tray, plan to use two packets of seeds, four packs for the medium tray, and eight packs for the large tray.
  4. Sprinkle a little bit of the remaining moistened Seed Starting Mix over the top of the seeds. It’s important not to cover the seeds with too much soil so the microgreens can emerge easily when germinating.

Step 3: Providing Optimal Conditions

  1. Place the Humidity Dome over the Perma-Nest Plant Tray to create a mini greenhouse environment.
  2. Find a sunny windowsill or use a grow light for optimal growth. Microgreens thrive with 12-16 hours of light daily.
  3. Ensure the growing medium remains consistently moist but not waterlogged. You can mist the seeds and the surface if needed.

Step 4: How to Care for Your Microgreens

  1. Keep an eye on the seeds as they germinate and grow. This process usually takes a few days to a couple of weeks, depending on the variety.
  2. Once the microgreens have grown to a desirable height (usually 1-2 inches), remove the Humidity Dome and continue to provide light and water as needed.


Step 5: Harvest and Enjoy

  1. Harvest your microgreens when they've developed their first true leaves. This is usually around 1-2 weeks after germination.
  2. Use clean scissors to snip the microgreens just above the soil line.
  3. Rinse the harvested microgreens gently under cool water and pat them dry.
  4. Most microgreens are one and done but some seeds are cut and come again. These include beans, peas, coriander, and kale. If you’re growing these seeds, return to Step 3: Providing Optimal Conditions.
  5. Enjoy your homegrown microgreens in salads, sandwiches, or as garnishes!

Step 6: Share the Joy

  1. Share the experience with family and friends! These microgreens make great gifts and are an excellent way to introduce gardening to kids.
  2. Follow the same steps to sow new seeds for a continuous supply of microgreens.

Delicious and easy, too, growing microgreens is a rewarding way to boost your nutrition and add some fresh, tasty greens to your diet. With just a few basic supplies and some patience, you can enjoy a bountiful harvest of these superfoods right from home.
