When can you plant in Olmos Park, TX?

Zone 9a

The last spring frost here typically falls around 02/25, about 181 days from today. The first fall frost typically arrives around 11/28, about 277 frost-free days later.

The USDA Plant Hardiness Zone Map puts Olmos Park in Zone 9a (20 to 25°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 02/25 isn't a guarantee

02/25 is the middle of 30 years of NOAA records, not a promise. Plant by 01/28 and you're betting against frost in roughly 9 years out of 10. 03/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
