Planting Information: Radishes require crumbly, well-drained soils. Sow at any time during the season, beginning when temps are reliably under 80º Direct sow ½” deep, 2-4” apart. Do succession plantings every two weeks to keep radishes coming. Way better to harvest too early than too late, as their flavor will turn spicy and too hot if not picked in their prime. Harvest beginning at about 3-4 weeks when roots are the size of a large marble. Bunch or top and refrigerate. Topped radishes will keep 3–4 weeks in good, crisp condition if kept at 32°F (0°C), 95% relative humidity, and in breathable packaging.
