How To Grow Sango Radish Microgreens

Want to add a touch of elegance and a burst of pungent-radish flavor? Say hello to my little friends: Sango Radish microgreens! These tiny powerhouses bring a subtle zing to your salads and culinary creations. In just 5-7 days, you’ll have an abundant harvest of these charming greens.

They’re like colorful confetti that packs a flavor and nutritional punch! So, let’s get our hands dirty and learn how to grow your very own Sango Radish microgreens. Ready? Let’s rock! 🌱🚀

Step 1 Preparing Your Sango Radish Seeds

Firstly, you’ll want to use a scale to measure your seeds. For a tray that’s 10″ × 20″ in size, the recommended seeding rate is between 25g and 30g. If you’re using a smaller tray measuring 10″ × 10″, simply divide the total amount by two, resulting in around 12.5g to 15g.

If you’re feeling a bit rebellious like me, you can skip the weighing process and just estimate the spacing between your seeds to be approximately ⅛ ¼” (3 6mm) apart.

After you have measured your seeds, there is no need to wash or pre-soak them. The reason being that Sango Radish seeds are small, with a diameter of about 3 to 4mm. If they get wet, it will become nightmare to evenly distribute them on your growing medium.

Step 2 Sowing Your Seeds

Prepare your tray by choosing a medium you prefer, such as soil, potting mix, or coco coir. Leave a gap of about 1 to 2cm between the edge of the tray and the level of the medium.

Keeping this space between the tray edge and grow medium will be beneficial during harvesting, as it reduces the risk of accidentally digging into the medium with your knife or scissors.

Ensure that you distribute and level out the medium evenly using your hands. This will prevent clumps from forming and avoid seeds from grouping when you sow them.

Start by lightly spraying your growing medium with a spray bottle until it becomes slightly damp, but not overly saturated.

Next, carefully distribute the seeds evenly across the surface of the medium. Take your time to ensure that they are spread out in a uniform manner. Finally, give the seeds a gentle misting with water so that they are all covered with a fine layer of moisture.

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 assists the seed’s radicle in penetrating the soil when it starts to grow. Without any weight, the radicles find it more challenging to dig into the growing medium and establish firm roots.

Keep in mind that the seeds will germinate while they’re covered and weighed down. A lot of people confuse the germination and weight period to be independent of one another and that you add them together, this is incorrect.

The germination time is there to give you an idea by what time the seeds will germinate, but you don’t add the germination time and blackout period together.

While your seeds are germinating and are weighed down you will need to keep your medium moist. You can do this by lightly 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 2 to 3 days, they should have sprouted and now you can carefully lift the empty tray. It’s time to remove the weight and begin the blackout phase.

Take your empty tray and flip it over to create a dome that blocks out light. Place it back over your seeds.

By keeping them in darkness for another 1 to 2 days, the newly sprouted seedlings will naturally stretch and reach out for light, helping them grow taller.

Now you can start watering your sango radish microgreens from the bottom. Simply add water to the drainage tray underneath. Personally, I recommend adding 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 to 2 days is over, you can remove the top tray or blackout dome and expose your microgreens to light. I’ve found that providing them with 17 hours of light followed by a 7 hour break works well for me.

Continue growing your Sango Radish microgreens for around 5 to 7 days, remembering to water them daily with approximately 2 cups of water per day. Once every 12 hours.

Step 5 Harvest

Harvesting your sango radish microgreens is a straightforward and simple task that only requires a sharp tool. Personally, I absolutely love using the Green Mercer Produce Knife—I highly recommend it! But if you prefer scissors, there’s also a fantastic option available; these sturdy and dependable heavy duty scissors.

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

By following this important pointer, you’ll ensure that your harvested microgreens are of top notch 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.

microgreens suffering from damping off disease

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.
