How to grow radishes

Radish is a root crop grown for speed. Sown directly into a row, it moves from seed to harvestable root faster than nearly any other vegetable, making it a natural first planting in a new bed and a forgiving crop for a gardener still learning a garden calendar. Home gardeners lean on radish to mark rows for slower-germinating crops like carrots, to fill gaps between larger plantings, and to bring a sharp, peppery bite to spring and fall meals. Because a single sowing matures on a tight window, small successive sowings every couple of weeks keep a steady supply of roots at pulling size instead of one large harvest all at once.

The hardest part of growing radish well is keeping soil moisture even while the root sizes up. Clemson Cooperative Extension notes that moisture stress during root development gives radishes a strong flavor and a woody, pithy texture, regardless of the weather. A second-year gardener who treats radish as maintenance-free often lets the bed dry out while attention goes to slower crops nearby. The tops keep growing and look fine, but the roots underneath turn cracked and spongy, a defect invisible until the radish is pulled and split open.
