Depending on the time of planting, the time of harvest will slightly differ.

Ideally, radishes should be grown in early spring or late fall.

Radishes should be harvested rapidly, as early as 3 weeks after planting. This applies to most radish varieties. In general, harvest radishes when you notice that the roots are about 1 inch in diameter above the soil surface.

The best time to harvest a radish is in early summer when it’s still at its prime.

In late summer, radishes are ready to pick once the seeds are ready to be harvested.

However, if you want to harvest radishes for the winter, you can plant them in the fall.

Harvest Radishes When They Mature (Obviously)

The first thing to keep in mind when harvesting radishes is that they are ready when they are mature.

To tell, you can pull them out and check the size. Also, remember that you should pull them when they are large enough to be pulled out. 

Then, when you’re ready to harvest radishes, you can measure them by how long they are when they’re still a few inches tall.

The Right Way to Harvest Radishes

When harvesting radishes, you should pull up the entire plant as soon as they’re large enough to handle. This may take a few days or a few weeks, depending on the variety. If the radish is large enough to be pulled up, it is ready. 

It should be about 1/2 to 1 inch wide. The leaves will start to turn brown once it’s mature, and the plant will continue to grow until it’s too old to pull up.

How to Tell When Radishes Are Ready to Harvest

You can tell when to harvest radishes by the way they look when they’re growing. You can feel the tops of the radish plants below the soil line. 

The soil around the roots will be softer. You can then pull them out of the soil with a handpicked. After that, you can wait for another 10-14 days until the soil is warm enough to harvest the radish.

It is recommended to harvest radishes at the earliest opportunity. Small garden radishes should be harvested within 21 days of planting, but some varieties can take up to 60 days to fully mature. 

While radishes are easy to grow, they need the right soil, sunlight, and water to grow well. When harvesting a radish, you can also check its size by lifting it from the ground. If it is bigger than the desired size, it should be picked sooner.

In a garden, radishes are an easy crop to grow. They require little maintenance and can fill in the space between other slower-growing crops. 

They can even serve as a row marker for slow germinating vegetables. You should ensure consistent moisture levels in the soil. If you have a lot of clay soil, you can use larger varieties of radishes.

You should wait until they are about 2.5 cm across and start popping up on their own. If you wait longer than this, the radish might end up becoming woody or pithy. 

Then, it will crack and become woody. You can then wash and store radishes in the fridge for two weeks. They can be stored for as long as three weeks, depending on how they grow in the soil.

How Big Should Radishes Be for Harvest?


the radish root should be about an inch in diameter. If the radish is too big, you can cut the root off. But if the root is too small, the radish should be harvested in early summer when it is already usable. 

This means that the radish plant’s roots are at least one inch in diameter. If the bud is too large, you must harvest it sooner.

Ideally, wait until they are about 5 to 10 days before their maturity date. Afterward, they can be stored in the fridge for up to 2 weeks. 

Nevertheless, you should make sure that the radish is ripe before it blooms or it will go to seed. Then, it will be ready to be harvested. If the radish is too small, you can pick it early.

After they’re ready to be harvested, you can use them as quickly as possible. You can harvest them when the roots are about 2.5 cm (1 inch) in diameter. Then, you can either dig beside them or pluck them out of the ground.

You can’t leave them in the ground for too long, as they will split into woody, bitter roots. 

Alternatively, you can use the green tops as salad greens or as garnishes for sandwiches.

When to Harvest White Radishes

The time to harvest white radishes depends on your climate and the type of soil. 

White radishes are best harvested in mid-July. The plant is ready to harvest in 21 days. Depending on the variety, the roots of the radish vary in size. 

Minowase is the largest of all Daikon varieties, measuring up to 24 inches in diameter. The roots are harvested by brushing the soil and trimming off the foliage. Once the white radish is ready for harvesting, it can be stored unwashed for up to two weeks.

Winter radish, also known as daikon or mooli, needs to be kept cool and shaded for the first three months. This crucifer grows well in full sunlight. You can plant it in the fall or early spring.

The best time to grow a white radish is during the spring or fall. Chinese white radishes need to be planted as soon as the soil is workable and can be tilled. 

Sow the seeds in full sun, four to six weeks before the last frost date in your area. The radish bed should be free of rocks or debris as this may inhibit its growth. When harvesting a white radish, it should quickly come out of the soil after twisting it.

The radish should be a minimum of 5 centimeters (2 inches tall in pots.).

The length of the radishes should be slightly deeper than the pot. A white radish should be at least five centimeters/2 inches in diameter. For long radishes, it is best to plant them a little deeper than this. Remember, they grow fast, so planting a white radish during the spring is important.

While many types of radish are suitable for growing in the spring and autumn, winter radishes require soil that is well-drained. 

Dig the soil to a depth of 30 cm. After removing the stones, sprinkle the soil with bonemeal and work it in with a trowel. It should take a few days for the radish to be ready for harvest. When to harvest white radish starts with digging the soil. 

The roots should begin to pop out of the ground.

What to Do After Harvesting Radishes

After harvesting, you should remove the tops and thin root tails. The white radish is best to be harvested when it is at its most mature stage. 

It is important not to leave the radish in the ground for too long. The roots will deteriorate, so be sure to pick them while they’re young. 

While there are many varieties of radishes, most are best grown in cooler climates.
