Antoine, AR 71922 Frost Dates
When can you plant in Antoine, AR?
Around 03/29 is the usual last spring frost, about 213 days away. The first fall frost typically arrives around 11/06, about 224 frost-free days later.
The USDA Plant Hardiness Zone Map puts Antoine in Zone 8a (10 to 15°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost

Why 03/29 isn't a guarantee
03/29 is the middle of 30 years of NOAA records, not a promise. Plant by 03/09 and you're betting against frost in roughly 9 years out of 10. 04/15 is the safer bet, historically only a 1-in-10 chance of frost that late.
