Dates are for a typical year and the middle of the window is the safest. Sow a little at a time across a window rather than all at once. Cold snaps, heat waves, frost pockets and city warmth all shift the real dates; watch the forecast.
Frost dates in Jacksonville
Jacksonville sees a frost only in some winters: half of all years have their last frost by February 1 and their first by January 5, so the risky stretch is a few weeks around midwinter. Keep fleece handy for tender plants then.
