Favor heat-aware timing: sow round types like Cherry Belle in early spring and again in fall, and reserve daikon and winter radishes for the prime fall window.

Growing notes

Even, consistent moisture is the single biggest factor in good radishes. Keep the soil steadily damp — never bone-dry, never waterlogged — so the roots swell quickly and stay mild and crisp. Irregular watering, especially a drought followed by a heavy soaking, causes the roots to split or turn pithy and unpleasantly hot. In dry spring weather that usually means a thorough watering every two to three days; in cool, damp conditions rainfall may be enough. Water at the base in the morning to keep foliage dry, and mulch lightly between rows to hold moisture and even out the soil temperature.
