When to Plant Radish Seeds

Plant your radish seeds 4-6 weeks before the average last frost in your area, or as soon as the soil is workable. If you want to plant in the fall, wait until it’s cooler out.

Where to Plant Radish Seeds

Plant your Radish in an area that gets full sun. Grow radishes in full sun or partial shade. They prefer loose, fertile, well-drained soil with a pH of 5.5 to 6.8. Planting radish seeds in pots produces the food quickly with minimum effort, but they can also be grown in the garden outdoors.

How to Plant Radish Seeds

Sow your seeds directly about ½ inch deep and about 1 inch apart. Thin the seedlings out to 2-3 inches apart.

How to Harvest Radish Seeds

Harvest your radishes as they mature, usually within less than 30 days, even if you don’t plan to eat them quite yet. This improves the continuation of growth and harvest opportunities. *Rotate your radishes to a different spot in your garden every 3 years.
