Bowling Green, KY 42122 Frost Dates
Bowling Green, KY: when does the frost end?
Around 04/05 is the usual last spring frost, about 220 days away. Fall's first freeze usually shows up around 10/31, roughly 208 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Bowling Green in Zone 7a (0 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 9 weeks until Bowling Green's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/05 isn't a guarantee
04/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/20 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/21 and only about 1 year in 10 sees frost after that.
