Manchester, VT 05152 Frost Dates
Manchester, VT: when does the frost end?
The last spring frost here typically falls around 05/16, about 261 days from today. Fall's first freeze usually shows up around 10/02, roughly 140 days after the last spring frost.

Stretching the season past the first frost
With roughly 5 weeks until Manchester'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
05/16 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/31 and only about 1 year in 10 sees frost after that.
