When can you plant in Sun, LA?
The last spring frost here typically falls around 03/12, about 196 days from today. The first fall frost typically arrives around 11/18, about 253 frost-free days later.
Sun 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.
What to do before the first frost
About 12 weeks of growing season left in Sun before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/12 isn't a guarantee
03/12 is the middle of 30 years of NOAA records, not a promise. Plant by 02/13 and you're betting against frost in roughly 9 years out of 10. 04/03 is the safer bet, historically only a 1-in-10 chance of frost that late.
