How to Grow Radishes

Radish Plant


Speedy, easy to grow radishes, are among the first vegetables in spring. Plant a few radish seeds, and a few weeks later, you are enjoying these zesty treats. Most radishes are red and round. There are cylindrical varieties. Colors include red, white, and bi-colored.

Radishes are quick growing. Sow seeds in the ground today, and you're picking them in about four weeks. The earliest varieties are harvested in as little as 20 days! And, they take up little garden space. We recommend succession planting of small rows, to spread the harvest out across the entire growing season.

Their sharp, zippy taste livens up salads, and are great with dips and dressings. They are perfect for the relish tray.

Radishes are a great first crop for kids. The seeds are big enough to handle. And, the harvest is quick.

Did You Know? Americans consume over 400 million pounds of this zesty little root each year.

How to Grow Radishes:

Grow radishes in full sun. They will grow in average soils. Work the soil a few inches deep, removing rocks and debris that may impede root growth. Add fertilizer when planting.

Sow seeds 1/2 inch deep. Space them 1 1/2 to two inches apart. Separate rows eight to ten inches apart. Try planting them in double rows, or broadcast spreading of seeds.

Thinning seedlings is important. Overcrowded plants, will not properly develop the root bulb.

Keep rows weeded, especially in the first week or two.

Keep the soil moist.

Radishes are a cool weather crop. But, they will be damaged or killed by frost.

Radish plants are great candidates for succession planting. Plant a small row about two weeks apart, and you'll have fresh radishes all season long, to spice up your salads and vegetable tray.



Harvesting Radishes:

Days to Maturity: 20 to 30 days. Note, some cylindrical varieties may require longer.

Harvest radishes as soon as they are big enough to eat. Do not let them get too big, or the roots will get tough.

Insects, Pests, and Disease:

Sucking and chewing insects may infest the leaves, but not overall growth of the radish.

Root maggots are a problem. Rotate the crop to a new location.

Few diseases affect radishes.
