Step by Step Growing Guide for Collard Microgreens

Our easy-to-understand and easy-to-follow step-by-step growing guide for collard microgreens will ensure that you can easily grow and harvest collard microgreens. We walk you through the process from beginning to end. You will learn how to prepare your growing trays, how to plant collard microgreen seeds, how collard microgreens germinate, how to grow micro collard greens, how to harvest collard microgreens, and how to store collard microgreens.

Step 1 Prepare Your Collard Microgreen Growing Trays

The first thing you must do is to prepare your growing trays for collard microgreens. Begin by placing the growing tray with holes inside a growing tray without holes. This setup allows you to water from the bottom, which can reduce the risk of mold, powdery mildew, and other soilborne diseases.

Once you have prepared your growing trays, it is time to add the soil and prepare for sowing collard microgreen seeds. Fill the grow tray with holes almost to the top with the growing medium, ensuring the growing medium is level from side to side. Use the remaining growing tray and gently press down to level the soil. If necessary, add more soil until the soil is slightly below the top of the tray.

Once you have filled your collard microgreen trays with soil, you will want to water your growing medium so that it is ready for the seeds. You can use your misting bottle to thoroughly water your soil from the top down, or you can water from the bottom up. If using the misting bottle, wet the soil thoroughly (approximately 10 squirts across the tray and allow it to soak in for 5 minutes, repeating the process five times to ensure the soil is amply moistened.  If you decide to water from the bottom up, lift your tray with holes up slightly and add an inch or two of water to the bottom tray. Replace the tray and allow the soil to soak up the water for approximately 30 minutes.

Step 2 Plant Collard Microgreen Seeds

You will need approximately 1 ounce of seeds for each 10 inch by 20 inch microgreen growing tray. Sow the seeds evenly across the entire surface of your grow tray. Then, gently press down to help set the seeds in the soil. Finally, sprinkle a small amount of soil atop your collard microgreen seeds and press the soil atop the collard microgreen seeds.

Once you have planted the seeds, you will need to water them before placing the germination tray atop the seeds. Grab your misting bottle and spray 10 sprays across the entire surface of the tray. The fine mist of water ensures the soil and seeds are properly moistened without disturbing them. This is why you should only water using a misting bottle during this step.

Step 3 Understand the Collard Microgreens Germination Process

After you have watered the seeds and soil, it is time to place the remaining tray atop the seeds and soil. Invert the tray and place a brick or heavy stone atop the third tray. The weighted-down inverted tray ensures that your seeds remain in total darkness during the germination process.

When seeds are planted in soil, the soil is placed atop the seeds, which blocks out all traces of light. When sowing microgreens in growing trays, only a small amount of soil is placed on top of the seeds. The inverted tray allows you to keep your collard microgreen seeds in complete darkness. Once you have placed the inverted tray atop your seeds, place the tray in a dark place like an unused closet.

Step 4 Place Your Collard Microgreens Under Grow Lights

Your collard microgreens must remain in complete darkness until during the germination process. Once your collard microgreens have germinated, you will remove the blackout tray and place your collard microgreens under the LED full spectrum grow lights.

Place your micro collard greens approximately 12 inches away from the grow lights and turn the lights on. Within just a few days, your pale, white collard greens will turn a beautiful dark green as photosynthesis occurs. Your collard microgreens will remain under these grow lights until your micro collards are ready to be harvested.

Step 5 Turn on Your Collard Microgreens Circulation Fans

One of the main things you can do to reduce the risk of mildew, mold, and other soilborne diseases is to use circulation fans. These fans increase airflow to your collard greens. Attach the circulation fans to the side of your planting rack and allow the air to blow horizontally across the microgreens rather than down on the plants.

Step 6 Know When to Harvest Collard Microgreens

Knowing when to harvest your collard microgreens is of vital importance. Most people find that the easiest way to determine the appropriate time for harvesting is to begin sampling collard microgreens as soon as the two cotyledons form and the first set of true leaves form.

Taste a small amount of collard microgreens daily until they develop the color, texture, and flavor you desire. Then, withhold water from your micro collard greens for 8 to 12 hours to ensure your collard microgreens remain crisp after harvest.

Harvesting Collard Microgreens

When it is time to harvest collard microgreens, you will need a clean paper towel or plate and a pair of sharp scissors or a sharp knife. Gently grasp the collard greens in one hand and cut the stem near the soil level, placing the freshly harvested micro collard greens on a clean paper towel.

The next step will depend on whether you plan on eating the collard microgreens immediately or storing the collard microgreens. If you will be eating the microgreens immediately, you will want to wash your microgreens. Conversely, if you will be storing the collard microgreens, you will not wash your microgreens. Instead, you will go to the next step and wash the microgreens when you are ready to eat them.

Washing your microgreens is simple. Fill a large bowl with cool, not cold water. Place the collard microgreens in the water and swirl to remove any dirt. Then, lay the freshly washed microgreens on a clean paper towel and allow the collards to dry before using.

Storing Collard Microgreens

Collard microgreens will store in the refrigerator for a week to ten days when they are properly stored. If you plan on storing or shipping collard microgreens, follow these directions as soon as you harvest your micro collard greens.

Microgreens must be stored in a cold refrigerator to maintain their crispness. Wrap the microgreens loosely in a clean paper towel and place them in an airtight storage bag or storage bowl. Place the storage container in the crisper drawer until you are ready to eat them. You will then remove them from the refrigerator and follow the instructions listed above on how to wash your collard microgreens.

Final Thoughts
