When can you plant in Leon Valley, TX?
Around 02/22 is the usual last spring frost, about 178 days away. The first fall frost typically arrives around 12/02, about 284 frost-free days later.
The USDA Plant Hardiness Zone Map puts Leon Valley in Zone 9a (20 to 25°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Why 02/22 isn't a guarantee
02/22 is the middle of 30 years of NOAA records, not a promise. Plant by 01/16 and you're betting against frost in roughly 9 years out of 10. 03/12 is the safer bet, historically only a 1-in-10 chance of frost that late.
