Palmetto, LA: when does the frost end?

Palmetto 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 13 weeks until Palmetto's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
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.
