Kohlrabi microgreens contain fiber and antioxidants that provide a number of health benefits. They fight against disease, reduce the risk of cancer, improve your heart health, and lower your blood pressure.

Kohlrabi Microgreens Growing Medium

There are two types of growing mediums commonly used for growing kohlrabi microgreens – seed starting soil and coconut coir. Both of these have a variety of advantages and disadvantages that should be considered. We recommend coconut coir because it holds moisture, is pH neutral, and reduces the risk of soilborne diseases.

Coconut Coir

Coconut coir is created using the husks of the coconut. This soilless growing medium is easy to use and is the perfect solution for kohlrabi microgreen gardens.

  • Plant directly in Mother Earth Coco + Perlite

Seed Starting Growing Medium

Seed starting growing medium is a soilless product that contains nutrients that new crops need to flourish. Because microgreens are harvested at such an immature stage, these nutrients aren't needed. The seeds will contain everything your kohlrabi microgreens need for growth.

Step by Step Growing Guide for Kohlrabi Microgreens

Are you ready to grow kohlrabi microgreens? Our easy step by step growing guide will provide you with easy to follow instructions to ensure your success. Follow our directions and you will be enjoying a bountiful harvest of kohlrabi microgreens within two weeks.

Step 1 Prepare Your Kohlrabi Microgreen Growing Trays

The first step is to gather your supplies and prepare your growing tray. Grab a ten inch by twenty inch growing tray with drainage holes and fill it with your growing medium. The growing medium should be filled to slightly below the lip of the tray.

Kohlrabi microgreens require moist, not sopping soil. There are two ways to ensure your soil is properly moistened – using your misting bottle or allowing your growing medium to soak in a sink of water.

If you will be using your misting bottle, evenly spray the soil with water, using approximately ten sprays. Then, allow the water to soak in for about fifteen minutes. Repeat the process three to five more times.

 If you will be soaking your growing tray in a sink of water, place the tray in an inch of water and allow it to soak for approximately thirty minutes. Then, allow any excess moisture to drain from the growing medium.

Step 2 Plant Your Kohlrabi Microgreen Seeds

Once your soil is thoroughly moistened, place your tray with drainage holes inside one of the trays without holes. Then, spread about three to four tablespoons of seeds evenly across your soil.

Use the remaining tray and gently press the seeds into the soil. Then, cover with a light layer of growing medium and press down with the lid to ensure the soil is even and level.

Step 3 Understand the Kohlrabi Microgreen Germination Process

Once you have planted your seeds, it is time to allow your seeds to germinate. Seeds need consistent temperature, no light, and evenly distributed weight. Take your remaining growing tray and invert it and place it on top of your seeds.

Place a heavy stone, heavy book, or weight atop the growing tray. Don't worry the weight will not hurt the seeds and will cause the roots to grow downward for better germination.

Finally, place your microgreen trays on your growing rack atop your heating mat and set the temperature to a balmy eighty degrees Fahrenheit. It will take your microgreen seeds approximately two to three days to germinate.

Check the soil's moisture level daily. If the soil has begun to dry out, either add a small amount of water to the bottom tray and allow the soil to draw moisture up for thirty minutes, or lightly spray the soil with your misting bottle.

Once ninety percent of the kohlrabi microgreen seeds have germinated, it is time to remove the weight and blackout lid. Now, the plants need bright light for optimal growth.

Step 4 Place Your Kohlrabi Microgreens Under Grow Lights

Once your kohlrabi microgreen seeds have germinated, you will want to place them in a well-lit area. Although your microgreens do not need direct sunlight, they will grow the best under a grow light.

The grow light should be placed approximately twelve to eighteen inches from the germinated microgreens. The lights should be left on for about eighteen hours each day. When grow lights are used, your microgreens will grow straight rather than stretching to one side or the other towards the light.

Step 5 Turn on Your Circulation Fans for Kohlrabi Microgreens

Once your kohlrabi microgreens have been placed under grow lights, it is time to turn on your circulation fans. Your circulation fans should blow across the tops of your kohlrabi microgreens, not across the top of the soil. Make sure your fans are blowing horizontally, not vertically or diagonally as this can dry out your soil too quickly.

Step 6 Know When to Harvest Kohlrabi Microgreens

Knowing when the best time to harvest kohlrabi microgreens is essential to tasty microgreens. They will be ready to harvest once the first set of true leaves form and the microgreens are two to three inches tall.

Many individuals are surprised to learn that the flavor of a microgreen can change within a day or two. To ensure delicious microgreens, begin tasting your microgreens when they reach two inches tall. Once your kohlrabi microgreens have reached the peak of flavor, it's time to harvest your microgreens. The best time to harvest is between day five and day fourteen.

Once the flavor has developed, withhold watering your microgreens for twelve hours. Doing this will ensure your kohlrabi microgreens are crispy and delicious. Furthermore, this will help increase storage times.

Harvesting Kohlrabi Microgreens

You will need very few supplies for harvesting your kohlrabi microgreens. All you will need is a paper towel, a pair of scissors or a sharp knife, and a storage box if you will not be enjoying them immediately.

Begin with clean, dry hands, and clean dry equipment. Then, gently grasp the microgreens loosely in your non-dominant hand. Then, using your scissors or knife, cut the microgreens slightly above soil level. Work quickly and place the cut microgreens on your paper towel.

It will only take a couple of minutes to cut an entire tray of kohlrabi microgreens. Once they have been harvested, you must decide what you will be doing with them.

If you will be eating immediately, dunk the microgreens in a bowl of cool, not cold water. Then, place them on a paper towel and allow them to dry before using.

Storing Kohlrabi Microgreens

If you will be storing your kohlrabi microgreens, the most important thing is to not allow one drop of moisture to touch the microgreens prior to eating. This means you should not wash them until you are ready to eat them.

Instead, as soon as you harvest your microgreens, place them in your favorite storage container or airtight storage bag. Then, place the bag in the crisper drawer of your refrigerator. For best results, the optimal storage temperature for kohlrabi microgreens is thirty five to forty degrees Fahrenheit.

Final Thoughts

Kohlrabi microgreens have a distinct flavor that can be added to salads, sandwiches, pasta, or used as a garnish. The brassica flavor pairs wonderfully with sharp flavors like radishes as well as sweet microgreens like corn microgreens.

Kohlrabi microgreens are extremely easy to grow. Once planted using our detailed step by step instructions, it will take between one and two weeks for your microgreens to be ready for harvest. Whether you are new to microgreen gardening or have been growing microgreens for several years, kohlrabi microgreens are a delicious microgreen to include in your repertoire.
