Marion, LA: when does the frost end?
The last spring frost here typically falls around 03/25, about 209 days from today. Fall's first freeze usually shows up around 11/05, roughly 226 days after the last spring frost.
Marion 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 10 weeks until Marion's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/25 isn't a guarantee
03/25 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/02 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/10 and only about 1 year in 10 sees frost after that.
