Radishes are a colorful and flavorful addition to salads, soups and salsas. Their crisp, spicy bite gives them a taste all their own. It is easy to grow radishes from seed in almost any soil type or climate. In fact, the season has some impact on their taste–radishes grown in hot temperatures tend to be spicier than their cool-weather counterparts.
Radish seeds germinate quickly; you’ll see seedlings pop up as soon as three days after planting. Since they grow so quickly, radishes are a great crop for kids to maintain, even though this root vegetables isn’t at the top of most kids’ favorites lists.
Plant radishes 2 inches apart under 1/2 inch of soil. Wide-row planting also works well for radishes, just sow the seeds randomly in a 3-foot-wide row. Since their roots are relatively shallow, radishes may also be grown in containers. When the seedlings emerge, thin them so each plant has 2 inches of clearance around it in all directions. Be sure that the root is fully covered while it expands. Keep the soil evenly moist. Although radishes thrive in cooler weather, they are frost-sensitive. Plant the last seeds just before your area’s average first winter frost date.
Radishes are quick to develop, some varieties are ready to eat in as little as 30 days! Harvest radishes when they are marble-sized. They will keep in the refrigerator for a few weeks. Since radishes provide such a fast crop, it makes sense to succession plant. Sow more seeds every two weeks to reap the benefits of season-long harvests!
