Zone 7a

The last spring frost here typically falls around 04/15, about 230 days from today. The first fall frost typically arrives around 10/26, about 194 frost-free days later.

The USDA Plant Hardiness Zone Map puts Sparta in Zone 7a (0 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 7a around Sparta 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 04/15 isn't a guarantee

04/15 is the middle of 30 years of NOAA records, not a promise. Plant by 03/31 and you're betting against frost in roughly 9 years out of 10. 05/03 is the safer bet, historically only a 1-in-10 chance of frost that late.
