Walker, MI 49435 Frost Dates
Walker, MI: when does the frost end?
Typically, the last spring freeze lands around 05/14, roughly 259 days out. Fall's first freeze usually shows up around 09/29, roughly 135 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Walker in Zone 6a (-10 to -5°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 5 weeks until Walker's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
05/14 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/29 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/31 and only about 1 year in 10 sees frost after that.
