Beardsley, MN: when does the frost end?

Zone 4b

The last spring frost here typically falls around 05/09, about 254 days from today. Fall's first freeze usually shows up around 09/28, roughly 141 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Beardsley in Zone 4b (-25 to -20°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Stretching the season past the first frost

With roughly 4 weeks until Beardsley's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 05/09 isn't a guarantee

05/09 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/28 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/22 and only about 1 year in 10 sees frost after that.
