35246, near Mulga, AL: the frost window

Zone 8a

Typically, the last spring freeze lands around 03/21, roughly 205 days out. Fall's first freeze usually shows up around 11/11, roughly 236 days after the last spring frost.

Mulga sits in USDA Zone 8a (10 to 15°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

Mulga's growing season runs out in roughly 11 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 03/21 isn't a guarantee

03/21 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/28 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/08 and only about 1 year in 10 sees frost after that.
