Fort Worth, TX: when does the frost end?

Zone 8b (15 to 20°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 Fort Worth, not a forecast for this year.
Stretching the season past the first frost
With roughly 13 weeks until Fort Worth's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/05 isn't a guarantee
03/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/16 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/25 and only about 1 year in 10 sees frost after that.
