When can you plant in Sumner, GA?

Zone 9a

Around 03/11 is the usual last spring frost, about 195 days away. The first fall frost typically arrives around 11/19, about 254 frost-free days later.

The USDA Plant Hardiness Zone Map puts Sumner in Zone 9a (20 to 25°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

How much risk comes with planting early here

03/11 is the middle of 30 years of NOAA records, not a promise. Plant by 02/18 and you're betting against frost in roughly 9 years out of 10. 03/29 is the safer bet, historically only a 1-in-10 chance of frost that late.
