Jackson, LA: when does the frost end?

Zone 9a

Jackson 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.

With roughly 12 weeks until Jackson's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

The actual range around Jackson's last frost

03/13 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/18 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/04 and only about 1 year in 10 sees frost after that.
