THE BENEFITS OF GROWING YOUR OWN RADISH SPROUTS

In case you need some convincing before you take this quick gardening project on (the no-mess gardening project is all I need), here are some of the advantages of growing your own radish sprouts:

 

  • Radishes are one of the fastest and most flavorful sprouts to grow. In addition to sprouting quickly, they have great germination rates.
  • Each little radish sprout contains as many nutrients as a fully grown radish plant. That includes vitamin A, vitamin B, vitamin C, vitamin K, calcium, iron, potassium, and zinc. These tiny plants are also rich in amino acids and fiber. They’re basically your new daily vitamin… but better.
  • You can grow sprouts indoors any time of year and with little setup or tending required.
  • You’ll have your radish “harvest” in just 5 days.
  • Radish sprouts have all the spicy flavor of their mature counterparts, but radish microgreens and sprouts don’t have to be chopped up before tossing them into your salad bowl.

RADISH SPROUT SUPPLIES

Here’s what you need as part of your simple setup to grow radish sprouts at home. 

Sprouting Jar or Container

Start off with items you have around the house. You’ll need either a glass jar (a clean mason jar is perfect) or a big bowl and then a strainer with small holes (you don’t want your radish seeds washing down the drain!). If you have a salad spinner with smaller holes, that could work instead. Once you’re hooked on sprouting seeds, you might consider buying a sprouting jar or sprouting tower to keep out on your counter. 

Organic Radish Seeds in Bulk

There’s nothing special about seeds designated for sprout use, except that they come in bulk at a better price per ounce than seeds intended for your vegetable garden. You’ll need a couple tablespoons of seed each time you grow radish sprouts. I recommend trying multiply varieties of radish seeds (winter radishes, daikon radishes, watermelon radishes, etc.). If you’re worried about E. coli or salmonella, check that your seeds have been tested by an independent lab for safety to avoid contamination. 

I love these China Rose Radish Sprout Seeds from Botanical Interests. They also have a fun Sandwich Mix that combines radishes with red clover and alfalfa sprouts. 

WATER

The last thing you need is just a source of clean water to rinse your sprouts. Room-temp water from your faucet should be just fine. 

STEPS TO GROW YOUR OWN RADISH SPROUTS

Follow these three simple steps to have fresh, delicious, and nutritious sprouts in just five days.

Soak Seeds Overnight

Soak 1-2 tablespoons of radish seed in fresh water overnight (or for about 6-12 hours) inside the jar or bowl. Fill your container with just enough water to cover all the seeds. I recommend covering your container with a lid, dish towel, or piece of cheese cloth for the night.

Drain the Water from Your Container

Once your seeds have been soaking at least 6 hours, allow the water to run out the drainage holes of your strainer or sprouting lid. Then, spread the seeds out over the strainer so that they can air dry a bit. You’ll continue soaking the seeds over the next few days, but you no longer want them to sit in excess water. That just leads to mold or mildew.

Pro Tip:

Don’t pour your sprout water down the drain! It’s filled with nutrients from those seeds now. Add it to your favorite houseplant’s soil to give it a little boost!

Rinse Your Radish Sprouts 2-3 Times a Day

Over the next couple of days, all you have to do is run your sprouts under water, spread them back out, and let them sit. Repeat once or twice more throughout each day. This is a good habit to just add in whenever you’re working near your kitchen sink, like making coffee in the morning, doing the dishes from dinner, etc. Cover your seeds back up for the night before you go to bed.

You should start to see little sprouts appear in just 2-3 days. After that, it’ll look like your sprouts are multiplying every time you check on them. It’s pretty satisfying to see!

Helpful tip: Don’t worry if you notice all those little root hairs are getting trapped in the drainage holes of your strainer. You don’t have to remove them. Just make sure there’s good air circulation around each little sprout at the top of the tray.

Your sprouts will grow without any light, but if you want them to be nice and green by harvest time, expose them to a little indirect sunlight on day 4 or 5. Plants need sunlight, of course, to synthesize chlorophyll and turn green. Without sunlight, you’ll have greenish yellow sprouts that are just as tasty and full of nutrition!

HOW TO HARVEST YOUR RADISH SPROUTS

Your radish sprouts should be ready in just 5 days. You should see lots of tiny heart-shaped leaves on pinkish or white stems.

All you have to do to “harvest” your radish sprouts is give them one final rinse. You’ll notice the seed hulls (the outer seed coats) are still mixed in with your sprouts. You can eat them if you’d like, or you can remove them (the better option if you’re not immediately consuming your sprouts, since those little hulls can trap excess moisture and cause mold). Just fill a large bowl with cool water and then give your sprouts a little swish. The hulls should float to the top for easy removal.

It’s a good idea to drain your sprouts really well before storing them in the fridge. They should stay fresh for 3-5 days.

HOW TO ENJOY YOUR RADISH SPROUTS

You can add your sprouts to any dish that needs a spicy kick! Toss them in salads and wraps and tacos and rice bowls. Mix them with some cottage cheese. Slather a piece of toast with cream cheese and then pile on the sprouts.

One thing to keep in mind is that these delicate little sprouts won’t hold up to cooking well. If you want to add them to a stir fry, toss them on in the last 20 seconds of cooking.

That’s all there is to growing your own sprouts. Once you’ve enjoyed your first batch, wash out your sprouting supplies and start another batch. Just think of all the flavor and nutrition you’re growing right on your kitchen countertop, in the tiniest and most adorable of little plant packages!
