Zone 6a

The USDA Plant Hardiness Zone Map puts Minden City in Zone 6a (-10 to -5°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 6a around Minden City has about 8 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 05/02 isn't a guarantee

05/02 is the middle of 30 years of NOAA records, not a promise. Plant by 04/19 and you're betting against frost in roughly 9 years out of 10. 05/17 is the safer bet, historically only a 1-in-10 chance of frost that late.
