Marshall, TX: when does the frost end?
The last spring frost here typically falls around 03/11, about 195 days from today. Fall's first freeze usually shows up around 11/17, roughly 250 days after the last spring frost.
Marshall sits in USDA Zone 8b (15 to 20°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.
Stretching the season past the first frost
With roughly 12 weeks until Marshall's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/11 isn't a guarantee
03/11 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/20 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/30 and only about 1 year in 10 sees frost after that.
