Like most microgreens, borage microgreens will not regrow once harvested. Once you harvest your borage microgreens, compost the roots and clippings. If you would like to have fresh borage microgreens each week, plant a second tray of borage microgreens one week after sowing your first tray of microgreens.

How Fast Do Borage Microgreens Grow?

Borage microgreens are fast growing. They will germinate within 2 to 4 days and can be harvested within 10 to 20 days from planting. The amount of light, moisture, and heat can affect their rate of growth. Warmer temperatures speed up their growth.

Specific Equipment Needed for Borage Microgreens

If you decide to purchase your equipment separately, you will need to purchase several items to ensure a bountiful harvest of borage microgreens, including:

Growing Medium – Borage microgreens are hearty and can successfully be grown in either a soilless medium like coconut coir or in an organic potting mix. When shopping for soil, you want fine-grained soil that drains well.

MOTHER EARTH Coco Plus Perlite Mix - For Indoor and Outdoor Container Gardens, Provides Strong Aeration & Drainage, 70% Coconut Coir, Resists Compaction, 50 Liter
  • Mother Earth Coco + Perlite is a great alternative to potting soil as it enables gardeners to aggressively feed and not worry about over-watering
  • Use Mother Earth Coco + Perlite with indoor and outdoor container gardens
  • Achieve better aeration and drainage with a mix that incorporates 70% of the finest coconut coir and 30% perlite
  • Plant directly in Mother Earth Coco + Perlite
  • Coconut coir resists compaction and last longer in a container (vs traditional growing media)

Growing Trays – For an optimal harvest, you will need two growing trays without holes and one growing tray with holes. This will allow you to water from the bottom to reduce the risk of mold as well as ensure your borage microgreens properly root. Most home microgreen growers prefer growing trays measuring 10 inches by 20 inches; however, there are also 10 inch square growing trays on the market.

Borage microgreens should be sown in a shallow growing tray with drainage holes. These holes allow you to water from the bottom up to reduce the risk of mold and other diseases from damaging your microgreens. Here are the growing trays with drain holes that we use:

Light Source – Borage microgreens require at least four hours of bright sunlight. If they are not receiving enough light, they can become leggy and pale. A grow light will help ensure your microgreens are receiving an ample amount of light for photosynthesis and a large harvest. You will need a grow light if you will be growing your microgreens during the winter to ensure your borage gets an ample amount of light.

Growing Borage Microgreens

Borage microgreens are easy to grow when you follow the step-by-step process defined below. Once you have read the tutorial and ordered your supplies, you will be enjoying borage microgreens within days.

Pre-Soaking and Planting Borage Microgreen Seeds

Borage microgreen seeds do not need to be presoaked. The seeds can simply be sown directly into the soil. To reduce the risk of mold, borage microgreens should be watered from the bottom tray.

  • Setting Up Your Growing Trays – You will need three growing trays for borage microgreens. Egin by placing a growing tray with drainage holes inside a tray with no holes. If you are only using one tray, you will want to put your soil in the solid tray and mist your soil using your misting bottle.
  • Fill Up Your Growing Trays – Next, you will want to fill your growing trays about three-fourths of the way full. Then, take one of your trays with no holes and gently pat the soil to level it and slightly compact it. Continue adding soil and patting down until the soil level is slightly below the top of the growing tray. Water the soil to help remove air pockets and ensure your soil is adequately moistened before planting your microgreen seeds.
  • Sow Seeds – When sowing borage seeds, you want to sow moderately heavy. Plan to use approximately 24 grams of seeds for each 10 inch by 20 inch tray. Spread the seeds evenly across your grow trays then sprinkle a layer of soil over your seeds.
  • Water – Once you have sown your seed, you will want to evenly water your seed and soil again. Spray the entire surface using your misting bottle, three times to ensure your soil and seeds are watered.

Growing and Caring for Borage Microgreens

The growing process begins with germination that takes place in the dark thanks to the third tray that is placed on top of the seeds. Then, as your seeds begin to sprout, the tray is removed, and photosynthesis occurs.

  • Install the Second Tray and Weigh It Down – After you have sown your seeds and watered them, place the second tray with no holes on top of your soil and seeds. Weigh the tray down with a brick to ensure your seeds are in total darkness. If you do not have a spare tray, you can over your growing tray with a couple of layers of newspapers.
  • Check for Sprouting at the End of Day 2 – After day two, remove the top tray and see how many seeds have sprouted. Check the moisture level of your soil. If the soil feels dry, you can gently spray; however, take care not to disturb the seeds that have not sprouted. Remember, overwatering is just as bad as underwatering when it comes to growing microgreens. Cover the seeds and sprouts back up and leave for one more day.
  • Germination – On day 3, most of your seeds should have sprouted. If more than three quarters of your seeds have sprouted, remove the cover and water from the bottom or use your misting bottle to gently water your microgreens. If less than three quarters have sprouted, place the lid back on and wait one more day.
  • Place under Light – Your borage microgreens require ample amounts of light to grow and flourish. You can place your microgreens in diffused sunlight or under a grow light. When microgreens receive enough light, they will transform from pale green to a beautiful vibrant green.
  • Turn on the Fan – Once you have removed the cover and placed your microgreens under your grow lights, you will want to turn your fan on to help circulate the air. Airflow helps to minimize the risk of mold and other diseases.
  • Continue Monitoring Your Borage Microgreens – You will need to continue monitoring your borage microgreens to ensure they are growing and getting the water they need. You may need to water several times as they grow. Remember to avoid overwatering as this can increase the risk of disease and mold.
  • Harvesting – Borage microgreens should be harvested when the cotyledons are fully developed, and they have reached approximately 1 to 2 inches in height. Depending on the amount of light the microgreens receive, the amount of water received, and the temperature of the soil, your microgreens will be ready to harvest between 10 and 20 days after planting.

Harvesting Borage Microgreens

Borage microgreens will be ready in approximately 2 to 3 weeks from when you first sowed your borage seeds. As your borage microgreens mature, tiny hairs can develop on the stem of the microgreens. If borage microgreens are allowed to fully mature, they will produce cornflower blue edible flowers.

  • Harvest Above Soil Level – Before you harvest your borage microgreens, make sure your scissors or knife is sharp and clean. Then cut your borage microgreens approximately one half of an inch above the soil level.
  • Clean Using Cool Water – Once you have harvested your borage microgreens, fill a clean bowl with cool, not cold water. Rinse your borage microgreens and place them on a clean paper towel to dry. You can use a fan to circulate the air to help them dry quicker.
  • Compost – Borage microgreens will not regrow once harvested. Place the roots, soil leftovers, and remaining bits in your compost.

Storing Borage Microgreens

Borage microgreens should be stored in an airtight container or zip lock bag in the refrigerator. When properly stored, borage microgreens should last between 5 and 10 days. If you will be eating them within 2 to 3 days, your microgreens can be placed between two paper towels and kept in the crisper.

If you will be shipping your borage microgreens, you will want to gently wrap the microgreens in paper towels before placing them in a sealed bag or container. The paper towel will absorb excess moisture and protect them from damage during transport. When properly packaged, your borage microgreens will last for several days.
