Hudson, WI 54016 Frost Dates
Hudson, WI: when does the frost end?
The last spring frost here typically falls around 04/22, about 237 days from today. Fall's first freeze usually shows up around 10/19, roughly 178 days after the last spring frost.

Stretching the season past the first frost
With roughly 7 weeks until Hudson'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
04/22 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/07 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/06 and only about 1 year in 10 sees frost after that.
