What Are Radishes?

The radish (Raphanus raphanistrum subsp. sativus) is an edible root vegetable of the family Brassicaceae that was domesticated in Asia prior to Roman times.

Radishes are grown and consumed throughout the world, being mostly eaten raw as a crunchy salad vegetable with a pungent, slightly spicy flavor, varying in intensity depending on its growing environment.

Radish Varieties

Some good radish varieties for growing microgreens include Cherry Belle, Sparkler, and French Breakfast.

These varieties are all known for their spicy and flavorful leaves, and they are well-suited for growing as microgreens.

Other radish varieties that are commonly used for microgreens include China Rose, Black Spanish Round, and Easter Egg and Daikon radish.

The China Rose radish is a very popular variety of microgreens. Red Rambo radish microgreens are another fast-growing, popular variety.

Most radishes have green leaves and purple stems but some varieties have purple leaves too.

It’s important to note that the flavor of radish microgreens can vary depending on the variety of radishes that were used to grow them, so you may want to experiment with different varieties to find the ones that you like best.

How To Grow Radish Microgreens In 7 Easy Steps

Growing radish microgreens is a simple process that anyone can do with minimal effort.

To Nature Jims Sprouts Salad Sprout Mix - Organic Salad Mix for Growing - Non-GMO Microgreen Seeds - Healthy Broccoli, Alfalfa, Radish, Clover Sprouting Seeds Variety Mix - Microgreens Growing 1lbget started, you’ll need some basic supplies such as soil, radish microgreen seeds, and a shallow tray or container.

Microgreen seeds will be certified organic and non-GMO.

Some garden seeds are treated with chemicals so you don’t want to use regular seeds unless you’re sure they are untreated.

You will not be growing mature plants but will be after the greens so you will not get mature radishes from them. We will walk you through the whole process.

1. Choose a Suitable Growing Tray

Make sure to use a shallow, wide container with drainage holes in the bottom. You can use recycled clamshells or other plastic containers but make sure to thoroughly clean them.

Bottom watering is a great way to water your radish seeds. You will want one microgreens tray with holes and one without.

You will put your growing medium in the top tray with holes. To water, you will fill the second watering tray partly full and place the tray with soil in it.

Watering this way will prevent washing your seeds around as with top watering methods. Don’t use cold water.

2. Fill Up Your Container With Soil

The first step is to add your soil to the container where your microgreens will be planted. Radishes grow so fast you don’t need any nutrients. The seed itself will feed your tiny plants.

Use a lightweight medium that drains well. You can use potting mix but you may need to lighten it up by adding some perlite.

3. Place The Radish Seeds Into The Soil

To start your next step bottom water your tray before seeding it. Don’t soak your seeds before planting because they will be harder to sow evenly.

Spread the radish seeds evenly over the surface of the soil. You can press them in with your fingers or cover them lightly with additional soil.

You want to sprinkle your radish seeds over the soil surface, leaving very little space between each seed for an optimal germination rate and a full tray.

After sowing your seeds give the tray a light misting with a spray bottle to make sure there is moisture for germination.

I like to place a seedling tray on top of the seedbed to help hold in moisture. When there are radish sprouts showing in a few days I take the tray off.  

Radish seeds will usually germinate in 3 days and then they will be ready to harvest in about a week. Keep your radishes at room temperature they are a cool weather crop. Avoid giving them too much water.

4. Place In A Bright Location

Place your tray in an area that receives some direct sunlight each day for up to 6- 8 hours for even growth.

Microgreens need plenty of sunlight, so make sure you place them in an area with a good light source.

If you live in North America there will not be enough natural light in most locations.

You will need to use supplemental lighting to grow your microgreen radish crop. This LED grow light will give great results.

5. Water Regularly

Keep your microgreens moist but not too wet, as this can cause fungal growth and rot in your microgreens. Don’t overdo it with bottom watering.

A fast crop like radishes probably only needs one bottom watering. From there use a spray bottle to give them a light misting or two every day.

6. Harvest When Ready

Radish microgreens are typically ready to harvest 7 days after planting. Once you see the first two leaves appear, they are ready to be harvested.

You can go until you start to see their first true leaves if you want in about 10 days.

 To harvest them, simply use scissors or a sharp knife to cut the microgreens at the base of the stem.

Make sure to use them soon after cutting and place any unused radish microgreens in the refrigerator to extend their shelf life.

This will help to ensure that the microgreens are as fresh and flavorful as possible. Never store microgreens in an airtight container they need ventilation.

7. Enjoy

Now that you’ve learned how to grow radish microgreens in 7 easy steps, it’s time to enjoy your harvest.

You can add them as a topping for salads or as a colorful garnish for dishes. 

You can store them for about a week in the fridge inside a plastic bag or container that has holes. Place a paper towel inside the container Here is more info on how to store microgreens.

Because the plants no longer have any leaves for photosynthesis they can not produce the energy or resources to regrow. 

If you want to continue to harvest radish microgreens, you will need to plant a new batch of seeds and start the process over again.
