Frost dates for Shreveport, LA, ZIP 71104
Around 02/28 is the usual last spring frost, about 184 days away. The first fall frost typically arrives around 11/24, about 268 frost-free days later.
The USDA Plant Hardiness Zone Map puts Shreveport in Zone 8b (15 to 20°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost

Why 02/28 isn't a guarantee
02/28 is the middle of 30 years of NOAA records, not a promise. Plant by 02/04 and you're betting against frost in roughly 9 years out of 10. 03/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
