When can you plant in Bellingham, MN?
The last spring frost here typically falls around 05/03, about 248 days from today. The first fall frost typically arrives around 10/02, about 151 frost-free days later.
The USDA Plant Hardiness Zone Map puts Bellingham 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 Bellingham before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/03 isn't a guarantee
05/03 is the middle of 30 years of NOAA records, not a promise. Plant by 04/21 and you're betting against frost in roughly 9 years out of 10. 05/15 is the safer bet, historically only a 1-in-10 chance of frost that late.
