Wayne, MI 48188 Frost Dates
Wayne, MI: when does the frost end?

Stretching the season past the first frost
With roughly 8 weeks until Wayne'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
04/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/10 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/11 and only about 1 year in 10 sees frost after that.
