Pittsfield, MA: when does the frost end?

Zone 5b

The last spring frost here typically falls around 05/13, about 258 days from today. Fall's first freeze usually shows up around 10/02, roughly 144 days after the last spring frost.

Stretching the season past the first frost

With roughly 5 weeks until Pittsfield'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

05/13 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 05/26 and only about 1 year in 10 sees frost after that.
