How to Grow Quick and Easy Microgreens

"Microgreens" is an umbrella term for a variety of leafy greens that are harvested in a very early stage of their growing cycle. This stage is called the "cotyledon growth stage" and is where the plants first set of true leaves sprout. Microgreens can be harvested as early as 14 days of growth! This is what makes them so appealing to the young, old, seasoned, and beginner gardeners alike. Common types of microgreens are as follows: kale, arugula, beet greens, onions, radish greens, dandelion greens, spinach, mustard, chard, bok choy, watercress, and herbs such as cilantro, basil, chervil, parsley, and chives.

The nutritional value of microgreens is exceptional as well and is likened to that of sprouts, but the two are not to be confused. Microgreens differ from sprouts in that sprouts are grown using only water and microgreens are grown with soil. The microgreens absorb nutrients from the soil as they grow, increasing their nutritional value. Also, since they undergo more photosynthesis than sprouts, they acquire more nutrients this way as well.

The nutritional and health benefits vary from green to green. Leafy greens are rich with beta-carotene, iron, and calcium. Darker leaved greens, like kale and chard, are additionally high in lutein and zeaxanthin, which both help protect your eyes from degenerative conditions. Even though the greens are small, they pack quite the nutritional punch, giving full meaning to the saying "a little goes a long way".

Because microgreens require only minimal sunlight and growing space, they are ideal to grow in a container on your kitchen windowsill for easy access. Since you are able to control the growing environment by planting the seeds yourself, you can choose to use fully organic growing methods.

Step by Step Instructions for Growing Microgreens

1. Select a shallow container with drainage.

We used fiber packs, which are a peat material. The size of the container should directly reflect how much you want to grow. Fill the container with 1.5"-2" of moistened potting mix or seedling mix. Press the layer of soil down gently to create a flat, even surface.Plastic seed labels and seed packets on a table

2. Select a microgreen seed that interests you.

Whether it be a mix or a singular type of green. The Pinetree Kitchen Sink Mix and Healthy Blend Mix are popular with our customers, and we offer a number of single green packs such as ArugulaCabbageCeleryCilantro, Beets, Basil, Broccoli, Kale, Sorrel, and more. Scatter the seeds over the surface of the soil before lightly pressing them down.dirt in container with plastic label.

3. Sift or sprinkle a very fine layer (1/8") of soil over the seeds.

We use germination paper (see photo). Make sure you have a drip tray under your container before watering the seeds as gently as possible. We used a sprayer to mist them. Place the tray on a sunny, south-facing window or under a grow light. The seeds will germinate within 3-7 days. Cover with a propagation dome or similar cover.

4. Keep the soil constantly moist.

Prevent it from being soggy by pouring off any excess water that collects in the drip tray. To harvest, snip the microgreens right above the soil line when their first true leaves appear (about 7-14 days after germination).

5. Harvesting your microgreens.

After harvest, it is time to start a new crop if you wish to have more greens. Harvesting them at such a young stage prevents them from producing a second crop on their own. The good news is that as long as you didn't have any issues with pests or diseases, you can reuse the soil. Simply pull up the remaining roots and stems and till the soil gently with a fork. Add more soil if needed and start the process over.

For continuous crops, use succession planting. Start a second crop of microgreens around a week after the first crop, the third crop about a week after the second crop, and so on. This will allow for a continuous harvest of delicious microgreens.

HI Linda! We do not actually sell germination paper at this time, but have found it previously on Amazon. We also still use a propagation dome with it. Thanks for checking!

Your microgreens are very interesting and appealing to me. I love greens in the Summer! Dandelions, beet greens, chard, etc. As well as mixed green tossed salads with chopped veggies. Mmm, Mmm! I’m getting hungry! Having some fresh greens year-round would be awesome. I’ll be planning an order. Thanks!

I’m interested in the germination paper you s hi owed in your blog on microgreens. I’ve tried paper towels in the past but they weren’t really that helpful since they dried out quickly. I usually cover the seedling trays with clear wrap and/or domes, but am intrigued by the paper. A web search didn’t turn up a supplier. Do you sell it?
