Atlanta, MO 63530 Frost Dates
When can you plant in Atlanta, MO?
Typically, the last spring freeze lands around 04/08, roughly 223 days out. The first fall frost typically arrives around 10/28, about 201 frost-free days later.
Zone 6a (-10 to -5°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 Atlanta, not a forecast for this year.
What to do before the first frost
About 9 weeks of growing season left in Atlanta before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/08 isn't a guarantee
04/08 is the middle of 30 years of NOAA records, not a promise. Plant by 03/23 and you're betting against frost in roughly 9 years out of 10. 04/24 is the safer bet, historically only a 1-in-10 chance of frost that late.
