When to harvest radish?

The Best Time to Harvest Radishes

Growing Conditions Matter

Radishes need good growing conditions for best eating quality. Plant in full sun or at least given them six hours of sun a day. Light, friable fertile soil – not too high in nitrogen – promotes growth and taste. Keep soil moist; dry conditions tend to make radishes hot. Whether grown in the garden, raised beds or containers, radishes should have soil at least three inches deeper than their roots.

Type of Radish and Harvesting

In addition to the classic spring radish – red, purple, white, pink and globe or carrot-shaped – other types of radishes are available. The edible podded or rat tailed radish is grown for its crisp, spicy pods rather than roots. These are also heat tolerant, so they are harvested over the summer. Winter radishes grow longer and larger, and are harvested at a larger size.


Although a radish “gourmet” might disagree, many people find spring radishes very similar. Not so with edible podded and winter radishes.

  • Cherry Belle, French Breakfast and White Icicle are typical spring radishes that mature at 22 to 27 days.
  • Rat-tailed Radish is grown in summer and its pods harvesting by cutting from the stalks.
  • Winter radishes (60 days) include Black Spanish, China Rose and Chinese White.

Spring Radish Size at Harvest

Early spring radishes can literally go from ready to overripe in just a few days. With an average maturity date of three or four weeks, the window is narrow. Check several days before the published maturity date and look for radishes about one inch in size. Pull the plant, wash and taste; if it’s ready, harvest the others.

Harvesting Edible Podded Radishes

Unlike their smaller cousins, edible podded radishes can grow three or four feet tall. They should be staked for easier harvesting. Pick or cut the pointed, lumpy pods, beginning about 50 days from planting. Keep the plants picked to encourage flowering and more seed pods. You can also simply pull up the whole plant when it is loaded with pods.

Harvesting Winter Radishes

Winter radishes will happily store in the ground most of the winter. These radishes may grow to sizes ranging from a baseball to several pounds. Harvest the first near the expected maturity date, then leave the rest in the ground throughout the winter. You may need to mulch in very cold climates. Don’t try to harvest once they start to grow again in spring.

Radishes are a quick producing vegetable which makes them always a great beginner plant to grow. After planting your seeds you only have to wait about 30 days before they’re ready to pick. Don’t you love that quick producing turnaround?

I hope you guys got your seeds planted after the How To I posted. I wanted to show you the harvest that we got that was picked from that very post. I am totally in love with these Radishes and have been including them in almost every single pasta dish we are eating. Who doesn’t love a radish as a snack too?

After a few weeks your radishes will begin to pop out of your container. They will just get bigger and bigger. Most radishes are ready to pick at around 30 days so once they’re popping out, just yank them up!

For radishes I will usually start by picking 1 or 2 to enjoy as I need it and then I’ll just clear the entire container and pick them all. Radishes store well so you can enjoy them for a few weeks after harvesting.

And then immediately after they were picked, a new bunch of seeds were planted! I’ll keep on doing this process until Fall.

Harvesting Radishes

Before harvesting radishes, it’s important to take a close look at the base of the plant. In most cases, the top of the radish should be visible. If it’s not, take a good look at the top of the plant. If the top is large and green and 6-8″ long, the radish is probably ready for harvest.

It’s always better to harvest radishes a little too early as opposed to waiting too long. When radishes are over-ripe, they get woody and pithy and aren’t nearly as tasty. We’d much rather eat a tasty radish that was a bit on the small side as opposed to a larger radish that was woody and didn’t taste very good.

When harvesting radishes, grasp the entire top firmly as close to the soil as possible and give it a gentle tug. The entire radish should come out fairly easily. Sometimes it helps if the soil is a little wet. You can water the plants a couple of hours prior to harvesting to make harvesting easier.

For fall radishes, get them harvested before the first hard freeze. If they are exposed to freezing temperatures,
their texture and flavor will start to deteriorate significantly.

Once the radishes are harvested, you can cut off the tops, leaving about 1/2 inch of stem. The tops can be washed and dried off with a salad spinner. They will keep nicely for 3 days or so in a non-airtight bag in the crisper drawer in your refrigerator.

The radishes themselves can also be washed and stored in the refrigerator in a non-airtight bag. They will last for a couple of weeks. The reason for not storing them in an airtight container is that gases will build up and cause the radishes to spoil more quickly. If we have room in our fridge, we usually just keep them in a bowl until we’re ready to cook or pickle them.

For long term storage, radishes can be pickled using your favorite pickling recipe. We like to use a sweet pickling liquid for radishes because we find that it contrasts nicely with the spiciness of the radish.

Now that you’re done picking radishes, it’s time for a few radish recipe ideas…

The radish is a cool-weather crop. Grow radishes in spring or fall for the best flavor and texture.

Sow radishes in the garden 2 to 3 weeks before the average date of the last frost in spring. Sow succession crops every 2 weeks in spring and in autumn.

Radishes require 22 to 70 days to come to harvest.

Complete the harvest before the weather grows warm. In mild winter regions, grow radishes in late autumn and early winter.

Description. The radish is a hardy cool-weather annual. Radish roots can be globe-shaped or long and tapered. Roots can be white, red, or black colored. Radishes form a rosette of lobed leaves on stems rising from the root.

Radish Yield. Plant 15 radishes per household member each month.

Thinning radishes allows for full root growth.

Planting Radishes

Site. Grow radishes in full sun or partial shade. Plant radishes in loose, well-drained soil. Remove soil lumps, rocks, and roots from radish planting beds. Obstructions can cause roots to grow malformed. Add organic matter to planting beds before sowing radishes. Radishes prefer a soil pH of 5.5 to 6.8.

Radish Planting Time. Radishes are a cool-weather crop. Sow radishes in the garden 2 to 3 weeks before the average date of the last frost in spring. Sow succession crops every 2 weeks in spring and in autumn. Two or more crops can be grown in spring. Radishes require 22 to 70 days to come to harvest. Complete the harvest before the weather grows warm. Warm weather can result in small roots. Long days may also cause radishes to flower; plant radishes during the shorter days of spring and autumn. In mild winter regions, grow radishes in late autumn and early winter. Radishes can withstand frost.

Planting and Spacing Radishes. Sow radish seed ½ inch deep and 1 inch apart; thin successful seedlings from 1 to 4 inches apart in wide rows depending upon the variety. Allow greater room for winter varieties. Space single rows or mounded ridges 10 to 16 inches apart.

Companion plants. Cucumbers, lettuce, nasturtiums, peas, peppers.

Container Growing Radishes. Radishes can be grown in containers. Sow radishes in containers at least 6 inches deep. Plant radishes in round containers in concentric circles. Move containers to cool locations if the weather grows warm.

Keep the soil evenly moist to ensure the best root growth.

Caring for Radishes

Water and Feeding Radishes. Keep radish planting beds moist but not wet. Even, regular watering will result in quick growth. Radishes that receive too little water will become woody tasting. Prepare planting beds with aged compost. Side dress radishes with aged compost at midseason.

Radish Care. Radishes will bolt or go to seed if grown during the long days of summer. Cover plants in midsummer so that they get 8 rather than 12 hours of sunlight. Keep radishes evenly watered so that they grow quickly. Slow growth will cause radishes to taste hot.

Radish Pests. Radishes can be attacked by aphids and root maggots. Pinch out infested foliage. Usually, radishes grow so quickly that pests are not a problem.

Radish Diseases. Radishes have no serious disease problems.

Harvesting Radishes

Radish Harvest. Spring radishes require 20 to 30 days to reach harvest. Winter radishes require 50 to 60 days to reach harvest. Radishes are ready for harvest when roots reach 1 inch across. Lift the whole plant when radishes are the right size. Lift a few or push the soil aside gently to decide if they are large enough to harvest. Do not leave radishes in the ground too long or they will become pithy.

Storing and Preserving Radishes. Radishes will keep in the refrigerator for 1 to 2 weeks. You can sprout radish seeds.

Black radishes

How To Pick Radish: When Do I Harvest Radishes

Radishes are an easy and rapidly growing crop that lends itself well to succession planting, which means an entire season of the crunchy, peppery roots. But what about harvesting radishes? Picking radishes at the correct time will enable you to enjoy the crop at its peak and dictate when to sow another planting. If you’re wondering “when do I harvest radishes,” read on to learn how to pick and when to pick radishes.

When Do I Harvest Radishes?

When you think of radishes, many people think of the small, round red type of radish but the fact is that there are a number of different types of radish in a variety of hues and sizes. Knowing what type of radish you are growing will tell you when to pick radishes.

The small red radish most of us are used to will be ready to harvest as soon as three weeks from planting. You can begin picking radishes when the roots are about an inch (2.5 cm.) across. Just pull one out to check on the size.

For winter radishes, such as Daikon, which can grow quite large before their quality deteriorates, pull before the ground freezes. Winter radishes can be stored in moist, cold storage for up to four months.

If you leave them too long before harvesting radishes, the root becomes quite pithy and, as temperatures warm, you risk the plant bolting.

How to Pick Radish

As previously mentioned, a good way to tell if the radishes are ready to be harvested is to simply pull one from the soil. If the soil is particularly crusted or hard, use a garden fork or trowel to gently lift the root from the soil.

Cut the tops and tail root from the radishes and wash them. Dry them well and store them in the refrigerator in a plastic bag until ready to use. Don’t forget about the radish greens! They are also edible and can be stored separately for up to three days.

Radishes can be planted and enjoyed throughout spring, summer and fall. They are great in salads and pasta dishes.

Radishes are root vegetables that are absolutely delicious and famous for both their taste and the ease with which they are grown.
