Radishes are a favorite vegetable to grow in home gardens thanks to their fast growth and spicy kick. But if you’re new to sprouting radish seeds, you may wonder – what does a radish sprout look like at each stage of growth?
In this complete visual guide, we’ll walk through the life cycle of a radish sprout with photos and descriptions. By the end, you’ll know exactly what to expect as these nutritious sprouts progress from seed to harvest!
Radish Seed
Radish sprouts begin as tiny, round seeds that are typically light brown or beige in color. Popular radish varieties used for sprouting include Daikon, China Rose, Champion, Cherry Belle and Icicle.
When purchasing radish seeds for sprouting, look for non-GMO, organic sources Reputable suppliers will often provide testing data to confirm the seeds are pathogen-free
Day 1 – Soaking
To kickstart germination, radish seeds are first soaked in water for 8-12 hours. This soaking period allows the dry seeds to fully imbibe water and swell up to double their original size.
Day 2 – Sprout Tail Emerges
After soaking, rinse and drain the radish seeds thoroughly. Over the next day, repeat this rinsing 2-3 times. Around day 2, you’ll notice a small white sprout tail (also called the radicle) emerge from one end of the swollen seed. It looks like a tiny thread.
Day 3 – Root Growth
With continued rinsing and draining 2-3 times per day the emerging root will lengthen and thicken. More extensive radish root growth becomes visible on day 3. The seed coats also split open as growth continues.
Day 4 – Leaf Growth
Around day 4, the first signs of leaf growth appear. Look closely – tiny green leaf buds will form at the top of the developing sprouts. They remain curled up at first.
Day 5 – Leaves Unfurl
On approximately day 5, the sprout leaves unfurl fully, revealing two small seed leaves on each radish sprout. They will likely be pale yellow or yellow-green since indoor-grown sprouts don’t photosynthesize.
Day 6 – Ready for Harvest
Once the seed leaves are fully open, the 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.

Growing Radishes, From Seed to Harvest
FAQ
What do radishes look like when first sprouting?
Above the soil, they sprout with two heart-shaped leaves, called cotyledons. Meanwhile, under the surface, radishes develop a taproot, which receives sugars from the photosynthesising leaves. It is these sugars that force radish roots to swell into crunchy, healthy tubers.
How long does it take for radishes to sprout?
Radishes can be sown after soils reach 40ºF. Seeds germinate best at 55-75ºF and require 5-10 days to emerge. Seeds should be planted ½ inch deep.
What does a radish seed look like?
Radish seeds are rounded and kind of a grayish light brown. They look like tiny pebbles. You can expect to find at least five to seven radish seeds growing inside each radish seed pod. In my garden, my plants will produce around 60 pods.
