Edgeley, ND 58433 Frost Dates

When can you plant in Edgeley, ND?

Zone 4b

Around 05/07 is the usual last spring frost, about 252 days away. The first fall frost typically arrives around 10/02, about 148 frost-free days later.

The USDA Plant Hardiness Zone Map puts Edgeley in Zone 4b (-25 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

About 5 weeks of growing season left in Edgeley before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/07 isn't a guarantee

05/07 is the middle of 30 years of NOAA records, not a promise. Plant by 04/24 and you're betting against frost in roughly 9 years out of 10. 05/20 is the safer bet, historically only a 1-in-10 chance of frost that late.
