The USDA Plant Hardiness Zone Map puts Manteo in Zone 9a (20 to 25°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
Zone 9a around Manteo has about 16 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.
Why 03/01 isn't a guarantee
03/01 is the middle of 30 years of NOAA records, not a promise. Plant by 02/03 and you're betting against frost in roughly 9 years out of 10. 03/21 is the safer bet, historically only a 1-in-10 chance of frost that late.
