Start the process of rinsing and draining your seeds again the next day. In the 12 hours or so after you soak the radish sprout seeds, make sure you rinse them at least twice a day for the next five to seven days.
These steps are so simple, right? No lights, no soil, no special tools required. And yet, you’re gardening.
In three to four days, the seeds will start to get a little bigger before a tiny white tail comes out. That tail is the radical, the very first root of the radish plant. The radical would look for food, light, and water if it were growing in soil, but since these plants are only sprouts, it will be happy with water for now.
As a health-conscious gardener, I love growing my own radish sprouts. These nutritious sprouts pack a peppery punch and make a crunchy addition to sandwiches, salads and more. But for beginners, the growth stages of sprouts can be a bit mystifying. If you’re new to sprouting, you may wonder – what does a radish sprout look like at each stage of development?
In this complete visual guide, I’ll walk you through the life cycle of a radish sprout with photos and descriptions so you know exactly what to expect day-by-day as you grow your own. Let’s start from seed and watch these sprouts progress!
Radish Seed
Radish sprouts begin as tiny, round seeds that are typically brown or beige in color. Some popular radish varieties used for sprouting include Daikon, China Rose, Champion, Cherry Belle and Icicle. When purchasing radish seeds for sprouting, look for a reputable supplier and non-GMO varieties.
Day 1 – Soaking
The first step is to place radish seeds in a jar or sprouting container and cover with water for 8-12 hours. This soaking period kickstarts the germination process as moisture is absorbed by the seeds. They will swell up to twice their dry size.
Day 2 – Sprout Tail Emerges
After soaking rinse and drain the radish seeds thoroughly. Over the next day, repeats this rinse and drain process 2-3 times. Around day 2, you’ll notice a small sprout tail (also called the radicle) emerge from one end of the swollen seed. It looks like a tiny little white thread.
Day 3 – Root Growth
As you continue rinsing and draining the seeds 2-3 times per day, the emerging root will lengthen and thicken. More extensive root growth will become visible on day 3. The seeds themselves will split open as the sprout grows.
Day 4 – Leaf Growth
Around day 4, you’ll notice the first signs of leaf growth. Look closely! Tiny green leaf buds will form at the top of the developing sprouts. They will be partially curled up at first.
Day 5 – Leaves Unfurl
On approximately day 5, the sprout leaves will fully unfurl, revealing two small seed leaves on each sprout. They will likely be pale yellow or yellow-green since radish sprouts grown indoors don’t receive light for photosynthesis.
Day 6 – Ready for Harvest
Once the sprout leaves are fully open your radish sprouts are ready for harvest! This occurs around 5-7 days after first soaking the seeds. Clip off the sprouts just above the root. Rinse thoroughly before eating.
Mature Radish Sprouts
At harvest time, mature radish sprouts will have:
- Root – White, slender, 1-3 inches long
- Stem – Pale green, slightly fibrous
- Leaves – Two seed leaves, yellow-green in color
- Height – Approximately 2-3 inches
- Texture – Crunchy
- Taste – Mild, peppery
So there you have it – a complete look at the life cycle of a radish sprout, from seed to harvest. Now that you know what to expect, you can grow these healthy, homegrown sprouts with confidence!

Supplies to Grow Radish Sprouts
As I already said, one of the best things about growing sprouts is how easy it is. All you need are some radish seeds, a sprouting jar or container, and fresh water.

This doesnt have to be anything fancy. You can start with things you already have at home and then improve your setup as much as you want if you find that you really enjoy adding sprouts to your tacos and sandwiches.
If you’re reusing things around the house, you’ll need a container that doesn’t drain, like a Pyrex dish, a glass jar, or a big bowl. Then you need something that can drain, like a strainer (the kind you use to get the water out of cooked noodles). Small holes in the bottom should allow water to drip through. This draining container will be set inside the non-draining container.
If youd like a designated container for growing sprouts, there are many inexpensive options on Amazon. Try these sprouting jars that come with a drip tray or a sprouting tower, which allows you to start multiple batches of sprouts at once or over the course of the week. My personal favorite is this stainless steel sprouting tower because I think it looks the best sitting out on my kitchen counter (Im constantly starting sprouts, so it never really gets put away.) You can find other suggested supplies here.
I really like the sprout seeds from Rainbow Heirloom Seed Co. There are three kinds of radishes in their radish seeds mix: the red arrow radish, the purple triton radish, and the white daikon radish. Look for non-GMO seeds from growers you can trust, and make sure you buy a lot of them (like a 1-pound bag). A small package of radish seeds costs a lot more per ounce, and they will only grow sprouts for a week or two.
(If you’re concerned about sprouts being contaminated with E. coli or salmonella, look for sprout packages that say an independent lab has tested a sample of each seed lot to make sure it is safe. ).
There is only one more thing you need to grow sprouts after you have your seeds and a way to rinse them. Water is the thing that tells your seeds to wake up from their nap. It swells inside each seed coat until the seed literally bursts open and starts to grow. I use water from the faucet that is at room temperature, but you can use a pitcher full of fresh water.

It’s a radish sprout! Radish sprouts are SPICY. Eating a single, tiny radish sprout can be give you a full radish-spice kick. Radish sprouts do very much still taste like radish, but they’re a whole new type of radish taste experience as opposed to biting a chunk off a whole radish.
What are radish sprouts?
Radish sprouts are germinated radish seeds that have just begun to produce leaves. They are an excellent source of vitamin C and mineral salts, and have remineralizing, antiseptic and diuretic properties, which are also useful in preventing asthma.
What do radish seeds look like?
These are called the “seed leaves”. All of the rest that form after that are called the “true leaves”, and those look exactly like miniature versions of the normal ones. Since you probably planted your radish seeds directly in your vegetable bed, caring for the seedlings is simple.
Do radish sprouts turn yellow?
That gives your radish sprouts a little spurt of leaf growth and they turn from a yellowy colour to a beautiful green. One last step before your sprouts are ready to eat. Put them in a colander and rinse them with fresh water to wash away the seed hulls and any seeds that didn’t sprout.
