When can you plant in Belgrade, MN?

Zone 4b

Typically, the last spring freeze lands around 05/04, roughly 249 days out. The first fall frost typically arrives around 10/04, about 152 frost-free days later.

Belgrade sits in USDA Zone 4b (-25 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 5 weeks of growing season left in Belgrade before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/04 isn't a guarantee

05/04 is the middle of 30 years of NOAA records, not a promise. Plant by 04/23 and you're betting against frost in roughly 9 years out of 10. 05/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
