Worley, ID 83876 Frost Dates
Worley, ID: when does the frost end?
Typically, the last spring freeze lands around 04/22, roughly 237 days out. Fall's first freeze usually shows up around 10/18, roughly 179 days after the last spring frost.

Stretching the season past the first frost
With roughly 7 weeks until Worley'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 04/04 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.
