Roseland, LA 70436 Frost Dates
Roseland, LA: when does the frost end?
Typically, the last spring freeze lands around 03/07, roughly 191 days out. Fall's first freeze usually shows up around 11/18, roughly 257 days after the last spring frost.
Roseland sits in USDA Zone 9a (20 to 25°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 Roseland's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/07 isn't a guarantee
03/07 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/10 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/31 and only about 1 year in 10 sees frost after that.
