Cabbage

Cabbage is normally set out as transplants rather than direct sown. It is hardy enough that transplants go out well before the average last frost. UF/IFAS gives North Florida one long planting window, September to February, rather than an autumn season and a spring one. Heads split if left standing once they have firmed, so the harvest window is about when to start cutting, not a period the crop can sit through.

From the guide: UF/IFAS gives the North Florida planting dates for this crop as September to February. It gives 85–110 days from seed to harvest, or 70–90 from transplants, 9–16 inches apart in rows 24 inches apart, sown ¼–½ in. deep. On the crop itself it says: Long fall/winter planting season. Buy clean plants to avoid cabbage black-rot disease. Needs ample moisture and fertilizer. Frost tolerant. Watch for caterpillars. The days-to-maturity figure on this entry is the one measured from transplanting, because that is what its planting window marks.

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.
