78353, near Falfurrias, TX: the frost window

Zone 9b

Around 02/25 is the usual last spring frost, about 181 days away. Fall's first freeze usually shows up around 12/01, roughly 285 days after the last spring frost.

Zone 9b (25 to 30°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Falfurrias, not a forecast for this year.

Stretching the season past the first frost

Falfurrias's growing season runs out in roughly 14 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 02/25 isn't a guarantee

02/25 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/19 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/18 and only about 1 year in 10 sees frost after that.
