Growing Beet Microgreens

Want to add a touch of elegance and a burst of earthy richness with a hint of sweetness? Look no further than beets microgreens!

Not only do they add a touch of sophistication to your plate, but they are also packed with nutritional goodness. In 13-21 days, you can grow a bed of these crimson gems.

Are you ready to experience the delicious and nutritious taste of beet microgreens? Let’s go and get our hands dirty!

Step 1 Preparing Your Seeds

First, you need to measure your seeds using a scale. The best seeding rate for a 10″ × 20″ tray is 30-45 grams. If you plan to grow them in a 10″ × 10″ tray then simply divide the total amount by two, in this case, 15-22.5 grams.

If you’re a rebel like me, you can just eyeball it without weighing; just make sure that your seeds are approx ⅛-¼” (3-6mm) apart.

Pro Tip 1
Some seeds perform better soaked, some do not. If you’re growing in soil you can skip soaking your seeds and sow them dry. You will need to test your seed lot to see if soaking or not works better for you.

After measuring the seeds, it’s important to give them a thorough rinse under running water using a colander. This will help remove any dirt, dust or other contaminants that may be present on the seeds.

Personally, I like to soak the seeds in mason jars for around 1-4 Hours. Once that time has passed, I drain the water and rinse them under running water one last time and drain thoroughly.

Step 2 Sowing Your Seeds

To get started, prepare your growing tray by filling it with your preferred medium such as soil, potting mix, coco coir, or any other medium you prefer. But make sure to leave 1-2cm of empty space between the tray edge and the soil level.

This space between the tray edge and the growing medium is beneficial during harvesting as it reduces the risk of accidentally digging into the medium with your knife and contaminating your harvest.

Pro Tip 2
Beets thrives in well-drained loamy soil and can also grow in other mediums, provided they are well-aerated.

Next, lightly mist your growing medium with a spray bottle to ensure it is damp but not overly saturated. Finally, evenly distribute your seeds across the medium, taking care to spread them out uniformly.

To finish off, I like to cover my seeds with a layer of vermiculite and another gentle misting so that it’s all covered with a fine mist of water.

Covering your seeds with a layer of soil or vermiculite aids in better germination, if you don’t have vermiculite, cover them with your grow medium.

Pro Tip 3
Beets prefer a slightly acidic to neutral soil pH ranging from 6.0 to 7.0. Soil that is too acidic or too alkaline can affect nutrient availability.

Step 3 Germination & Weight Period

Take an empty tray without any holes and put it on top of the seeds you have planted. I usually use a 15lb (6.80kg) paving block for trays that are 10″ x 20″ or a 7lb (3.17 kg) brick for trays that are 10″ x 10″.

This method helps the seed radicle to penetrate the growing medium easily when it starts to emerge. Without any weight, the radicles may struggle to dig into the growing medium.

Pro Tip 4
Beets thrive in cool weather and prefer temperatures that are not too extreme. Beets optimal germination range is around 60°F to 75°F (15°C to 24°C). Warmer temperatures may result in faster germination.

Remember that the seeds will start to sprout when they are covered and pressed down. Many people tend to mix up the germination and weight periods and mistakenly combine them, but this is not correct.

The purpose of the germination period is to provide an estimate of when the seeds will sprout. However, it is important to note that you should not add the germination time and blackout time together.

During the germination period, make sure to keep your growing medium moist while your seeds are weighed down. You can achieve this by gently misting your seeds every 12 hours. Once in the morning and once at night.

Step 4 Blackout Time

After allowing the seeds to rest for about 4-5 days, you should notice that they have germinated and the seedlings are now lifting the tray with the weight. It’s time to remove the weight and begin the blackout period.

Remove the weight from your empty tray and turn it upside down to create a dome that blocks out light. Place it back over your seeds.

Keeping them in darkness for around 1-2 days will encourage the newly sprouted seedlings to stretch and search for light, helping them grow taller. I prefer doing 1 day of black out.

Now you can start watering your beets microgreens from below. Simply add water to the drain tray at the bottom. Personally, I add 1 cup of water twice a day. Once in the morning and once in the evening (every 12 hours).

Once the blackout period of 1-2 days is over, you can remove the top tray or blackout dome and expose them to light. I’ve found that giving them 17 hours under lights followed by 7 hours of darkness works well for me.

Continue growing your beets for about 8-13 days, making sure to water them daily with 2 cups of water per day, spaced out every 12 hours.

Step 5 Harvest

Harvesting your microgreens is straightforward and only requires a sharp tool. Personally, I absolutely love using the Green Mercer Produce Knife—I highly recommend it! But if you prefer scissors, that’s also completely fine; just make sure they’re sharp!

Here’s an important tip to keep your harvest pristine: keep your chosen tool (whether it’s a knife or scissors) away from the soil! It’s imperative to avoid any accidental contact between the blade and the soil; you don’t want any unwanted dirt sneaking into your microgreen harvest and contaminating it.

It is crucial to follow this advice to guarantee that your harvested microgreens are of the highest quality and purity.

Microgreen Pests & Diseases

The following are the most common pests and diseases that can affect your microgreens.


White Mold – Sclerotinia sclerotiorum

Sclerotinia sclerotiorum is a necrotrophic fungal disease that causes what’s known as white mold, it can infect over 400 plant species worldwide. It’s also called cottony soft rot, stem rot, watery soft rot, crown rot, and seedling blight.

S. sclerotiorum key properties are its ability to create sclerotia which are its black resting structures, and mycelium which are the white fuzzy spiderweb-like growths you see on stems and growing medium.

Damping Off

Damping-off is an umbrella term that covers fungi and fungi-like organisms in several genera including Rhizoctonia, Botrytis, Phytophthora, and Fusarium, with the soil fungus Pythium being the often culprit.

Damping-off is a soil-borne fungal disease that affects seeds and seedlings typically by rotting of the stems and roots at and below the soil surface.

When a seed germinates the seedling will emerge fine but within 24 hours to a few days will become mushy and water-soaked, collapse at the base of the stem and die.

Aphids crawling on a plant stem

Aphids – Aphidoidea

Aphids suck! Quite literally. They’re soft-bodied insects that use their piercing-sucking mouths to feed on plants and there are over 4,000 aphid species in the world.

Other common names are greenflies, blackflies, and plant lice. They come in varying colors such as light green, black, white, brown, gray, or yellow.

When aphids feed on plants they secrete a sticky fluid which is called honeydew (no, don’t eat it). This goo they leave behind drips onto plants and can attract other pests such as ants. If the honeydew is left on leaves it can promote black sooty mold.
