Hartington, NE 68749 Frost Dates
Hartington, NE: when does the frost end?
The last spring frost here typically falls around 04/30, about 245 days from today. Fall's first freeze usually shows up around 10/05, roughly 159 days after the last spring frost.

Stretching the season past the first frost
With roughly 5 weeks until Hartington'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
04/30 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/17 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/13 and only about 1 year in 10 sees frost after that.
