Crestwood, KY: when does the frost end?

Zone 6b (-5 to 0°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Crestwood, not a forecast for this year.
Stretching the season past the first frost
With roughly 8 weeks until Crestwood's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/12 isn't a guarantee
04/12 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/29 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/01 and only about 1 year in 10 sees frost after that.
