When can you plant in Ridgeland, MS?
Around 03/06 is the usual last spring frost, about 190 days away. The first fall frost typically arrives around 11/19, about 258 frost-free days later.
Ridgeland sits in USDA Zone 8b (15 to 20°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 Ridgeland before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/06 isn't a guarantee
03/06 is the middle of 30 years of NOAA records, not a promise. Plant by 02/15 and you're betting against frost in roughly 9 years out of 10. 03/24 is the safer bet, historically only a 1-in-10 chance of frost that late.
