Redfield, KS 66769 Frost Dates
Redfield, KS: when does the frost end?
Typically, the last spring freeze lands around 04/05, roughly 220 days out. Fall's first freeze usually shows up around 10/28, roughly 204 days after the last spring frost.
Zone 7a (0 to 5°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 Redfield, not a forecast for this year.
Stretching the season past the first frost
With roughly 9 weeks until Redfield'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 03/21 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/22 and only about 1 year in 10 sees frost after that.
