Cucumber

Cucumbers are direct sown after frost risk has passed and again in late summer. In the humid Gulf Coast summer, downy mildew arrives reliably and is normally what finishes a planting, so the autumn sowing is planned as a separate crop rather than as insurance.

From the guide: UF/IFAS gives the North Florida planting dates for this crop as March to April, and again August to September. It gives 40–65 days from seed to harvest, 6–12 inches apart in rows 48 inches apart, sown ½–¾ in. deep. On the crop itself it says: Two types: slicers and picklers. Many hybrids are gynoecious (female flowering; only female flowers set fruit). Bees are required for pollination.

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.
