Mount Zion, GA: when does the frost end?

Zone 8a (10 to 15°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Mount Zion, not a forecast for this year.
Stretching the season past the first frost
With roughly 10 weeks until Mount Zion's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/28 isn't a guarantee
03/28 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/07 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/12 and only about 1 year in 10 sees frost after that.
