Windows below are from UGA Cooperative Extension, Vegetable Gardening in Georgia, Circular 963, retrieved 2026-10-10. Circular 963, revised June 2023, prints one vegetable planting chart for the state. It does not give separate dates for North, Middle, and South Georgia. Where several cultivar rows share a crop name, the page uses the dates those rows print in common and names the row when a date differs.
