42134, near Franklin, KY: the frost window

Zone 7a

Typically, the last spring freeze lands around 04/05, roughly 220 days out. Fall's first freeze usually shows up around 11/01, roughly 210 days after the last spring frost.

Franklin sits in USDA Zone 7a (0 to 5°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

Stretching the season past the first frost

Franklin's growing season runs out in roughly 9 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

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 03/21 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/19 and only about 1 year in 10 sees frost after that.
