71333, near Evergreen, LA: the frost window

Zone 9a

Typically, the last spring freeze lands around 02/28, roughly 184 days out. Fall's first freeze usually shows up around 11/24, roughly 270 days after the last spring frost.

Evergreen 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

Evergreen's growing season runs out in roughly 13 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 02/28 isn't a guarantee

02/28 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/31 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/21 and only about 1 year in 10 sees frost after that.
