When can you plant in Coppell, TX?
Typically, the last spring freeze lands around 03/08, roughly 192 days out. The first fall frost typically arrives around 11/24, about 262 frost-free days later.
The USDA Plant Hardiness Zone Map puts Coppell in Zone 8b (15 to 20°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 03/08 isn't a guarantee
03/08 is the middle of 30 years of NOAA records, not a promise. Plant by 02/17 and you're betting against frost in roughly 9 years out of 10. 03/26 is the safer bet, historically only a 1-in-10 chance of frost that late.
