Montpelier, OH: when does the frost end?
The last spring frost here typically falls around 04/26, about 241 days from today. Fall's first freeze usually shows up around 10/17, roughly 170 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Montpelier in Zone 6a (-10 to -5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
With roughly 7 weeks until Montpelier's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/26 isn't a guarantee
04/26 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/14 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/11 and only about 1 year in 10 sees frost after that.
