Flatonia, TX: when does the frost end?

Zone 9a (20 to 25°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 Flatonia, not a forecast for this year.
Stretching the season past the first frost
With roughly 12 weeks until Flatonia's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/12 isn't a guarantee
03/12 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/18 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/11 and only about 1 year in 10 sees frost after that.
