Planting Radish

Prefers well-drained, loose soil, high in organic matter, free from stones, with pH 5.8 to 6.8 but can grow almost anywhere. Prepare soil by working compost into the top 2 to 3 inches. Sow seeds 1/2 inch deep about 1/2 inch apart in rows 8 to 15 inches apart. When seedlings emerge, thin to 2 inches apart in the row.

Growing Radish

Radishes have a shallow root system so they require plenty of consistent moisture.

Harvesting and Storing Radish

Harvest round radishes when the roots are the size of a quarter or less than 1 inch in diameter. Young radishes have the best flavor, so pull them promptly.

Radish Insect and Disease Information

Flea beetles can be controlled with applications of Retenone-Pyrethrin.

Radish Yield Information

Because radishes mature quickly, radishes make a good inter-crop along with slower growing vegetable plants. For continuous harvest, make additional plantings every week or 2 until temperatures average in the mid 60s; you can once again begin planting in the fall.
