When can you plant in Aransas Pass, TX?
Around 01/16 is the usual last spring frost, about 141 days away. The first fall frost typically arrives around 01/05, about 365 frost-free days later.
The USDA Plant Hardiness Zone Map puts Aransas Pass in Zone 10a (30 to 35°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Why 01/16 isn't a guarantee
01/16 is the middle of 30 years of NOAA records, not a promise. Plant by 02/23 and you're betting against frost in roughly 9 years out of 10. 12/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
