When can you plant in East Ridge, TN?
Typically, the last spring freeze lands around 03/24, roughly 208 days out. The first fall frost typically arrives around 11/09, about 230 frost-free days later.
The USDA Plant Hardiness Zone Map puts East Ridge in Zone 8a (10 to 15°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Why 03/24 isn't a guarantee
03/24 is the middle of 30 years of NOAA records, not a promise. Plant by 03/06 and you're betting against frost in roughly 9 years out of 10. 04/08 is the safer bet, historically only a 1-in-10 chance of frost that late.
