Radishes go from sowing to pulling in about a month, so they are sown a short row at a time rather than all at once. Left in warm soil they turn pithy and hot, which is what ends the spring window rather than any date.
From the guide: UF/IFAS gives the North Florida planting dates for this crop as September to March. It gives 20–30 days from seed to harvest, 1 inches apart in rows 6 inches apart, sown ¼ in. deep. On the crop itself it says: Easy and fast-growing; thin early. Plant every two weeks during the growing season for a continuous supply. Spicy, bitter flavor caused by hot weather and over-maturity.
Where these dates come from: the North Florida column of the UF/IFAS Extension Florida Vegetable Gardening Guide (SP 103/VH021), which defines North Florida as everything above State Road 40. Walton County is well inside it, and the Central and South Florida columns of the same table give different months. The guide is written for home and market gardens, so its spacing and days-to-harvest figures are a starting point for a field planting rather than a commercial schedule, and days to harvest varies by variety.
