Commonly Asked Questions

How long does it take for radishes to grow?

Salad radishes are best harvested young, in as little as four weeks from germination, when the roots are about 2.5cm (1in) in diameter and mildly peppery. Early sowings take a little longer, ready in six to eight weeks. If left to get too large or old, or to grow slowly, they become pithy, hot, and inedible.

What month is best to plant radishes?

Plant radish seeds from early April through early May for a spring crop, and again August through September for a autumn crop. Allow about one inch between plants in the row. Plant smaller varieties shallowly, one-fourth to one-half inch deep. Plant larger varieties deeper, up to one inch deep.

How do I know when my radishes are ready?

Radishes are ready to harvest when the leaves are 4 inches tall. Red radishes are ready to harvest when the roots are approximately 1 inch in diameter. White radishes are ready to harvest when the roots are 3/4 inch in diameter. To harvest, pull the entire plant straight up from the soil.

Do radishes like full sun or shade?

Radish plants prefer full sun, but they can tolerate partial shade. Choose a planting area that gets at least six hours of sunlight per day. Prepare the soil. Radishes prefer loamy, well-draining soil with an average to slightly acidic soil pH level (between 6.0 to 7.0).

What is the secret to growing radishes?

Radishes prefer fertile, well-drained, deep, sandy soils rich in organic matter for the best growth. Most light soils in Utah are well-suited for radish production. Heavy soils need to be amended with plenty of compost to allow good root development.
