Starbuck, MN: when does the frost end?
The last spring frost here typically falls around 05/11, about 256 days from today. Fall's first freeze usually shows up around 09/27, roughly 139 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Starbuck 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 Starbuck's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/11 isn't a guarantee
05/11 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 05/27 and only about 1 year in 10 sees frost after that.
