How to Grow Radish Sprouts in a Jar (In 5 Days!)

Radish sprouts are extremely nutritious. And, fortunately, they’re incredibly easy to grow at home. You don’t even need sun or soil.

Plus, if you’re short on space, you’ve found a perfect match. You’ll see how to grow radish sprouts in a jar, which just requires a little bit of room on your kitchen counter.

Even better:

You don’t have to wait a long time to harvest your food. Radish sprouts are ready in just five days.

And, sprouting your own seeds definitely has its advantages. You’ll save money for one thing. You can also choose to grow daikon sprouts and other popular radish varieties.

So let’s get started. Whether your interested in picking up a new hobby or you want to become more self-sufficient with food, I hope you get a lot of value from this information.

Radish Sprouts By Color

Before you start sprouting your seeds, think about the radish varieties you’d like to try.

Personally, I like to sprout colorful radishes just for the fun of it. 🙂 If you’d like to do the same, here are four different radish varieties (with their colors in parenthesis) that you might enjoy.

​Colorful Radish Varieties

• Red Vulcano (red)

• Daikon (green)

• China Rose (pink)

• Rambo (purple)

True Leaf Market has many different varieties of radish sprouting seeds (including the ones listed). For another option, here’s a colorful trio of radish seeds on Amazon.

​Seed Sprouting Supplies

You don’t need much to start sprouting. In fact, you probably have a lot of these items already.

Specifically, here’s what you’ll need:

• Radish sprouting seeds (2 TBSP to 3 TBSP)
• ​Mason jar (quart size, wide mouth)
• Sprout​​ing lid
• Filtered water
• Bowl

Radish Sprouts Growing Instructions

Here are the steps to sprouting your radish seeds in five days. (There’s also a video and printable instructions further down the page.)

Soaking Radish Seeds

On the first day, add 2 to 3 TBSP of radish seeds to a clean mason jar. Fill the jar halfway with filtered water and then screw on the lid.

Now, place your jar in an area out of direct sunlight and in an open air environment. (For instance, the top of a kitchen counter.)

Draining and Rinsing Seeds

On the second day, drain the water out of the jar. (You don’t need to remove the lid as the water will come out of the holes in the top of the sprouting lid.)

Fill the jar with fresh water and then drain it out immediately again. This is how you rinse your seeds. Repeat this rinsing process again.

Now, position your jar in a bowl at an angle. This helps continually remove the excess water throughout the day.

Later on, repeat the rinsing process. If you rinsed your seeds in the morning, for example, do it again in the evening.

Daily Rinsing Schedule

For the remaining days, repeat the rinsing process two times a day. Be sure to put your jar back in the bowl (at an angle) so that the water continues to drain between rinses.

It’s very important to rinse your seeds and allow them to drain to keep bacteria from developing.

Are your radish sprouts fuzzy? Don’t worry! Those are just the tiny white root hairs that normally develop.

Harvesting Radish Sprouts

By the fifth day, your jar should be filled with sprouts that are ready to eat! Simply give your sprouts a final rinse and then place them in a bowl.

You’ll probably notice some remaining radish seeds that didn’t sprout. To get rid of them, fill the bowl with water, then place your hand over the sprouts as you tilt the bowl to drain the water. Repeat this process as many times as you prefer.

How To Store Radish Sprouts

Sprouts are stored in the refrigerator after they’re dry. Use paper towels or a salad spinner to remove the moisture.

Afterwards, your radish sprouts can go in a container or plastic bag. I usually store mine in another jar with a sprouting lid for the airflow.

Be sure to eat your sprouts within 7 days.

Here’s a video that shows the whole process of growing radish sprouts in a jar.

How To Eat Radish Sprouts

If you eat mature radishes, you know that these veggies have a spicy flavor. Radish sprouts are no exception. In fact, I find that these sprouts have a very peppery and more intense radish flavor.

Raw radish sprouts can be added to so many meals where you want that crunchy, spicy kick.

Here are some suggestions:

These sprouts are also great on their own as a snack. You might find (like me) that once you have these sprouts in your fridge, you’ll often start adding them to everything!

When To Start A New Batch Of Sprouts

To keep a constant supply, I usually sprout new radish seeds after a couple of days. (Or, when I’ve eaten about half of my sprouts.)

You might want to do the same, and then adjust your growing schedule after you see how often you eat them.

Other Ways To Grow Radish Sprouts At Home

You’ve just learned about growing sprouts in a jar, but you have more options that you can use.

For example, other common methods include using sprouting containers, bags and trays. The sprouting method is similar in that you rinse seeds twice a day over a period of a few days. You might choose one over the other depending on how many radish sprouts you want to produce at a given time.

You can have multiple sprouting jars to increase your output, but you can also use something like these multi-level sprouting trays. For example, here’s how I use trays for growing broccoli sprouts.

Where To Buy Radish Sprouts

In the event that you don’t start sprouting radish seeds right away, you can buy sprouts that are ready to eat. (Be sure to download the instructions below so you can reference them when you’re ready.)

You can purchase radish sprouts in healthy food stores and farmer’s markets. If you happen to be looking for Kaiware sprouts — daikon radish sprouts used as a garnish, in salads and sushi — you can find them in Japanese and Asian grocery stores.

I hope this article gets you excited about sprouting seeds. Whether you call them radish sprouts or radish microgreens (some people do), it’s empowering to be able to grow these superfoods at home.
