Lebanon, KS 66952 Frost Dates
Lebanon, KS: when does the frost end?
The last spring frost here typically falls around 04/24, about 239 days from today. Fall's first freeze usually shows up around 10/15, roughly 173 days after the last spring frost.
Zone 6a (-10 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 Lebanon, not a forecast for this year.
Stretching the season past the first frost
With roughly 7 weeks until Lebanon's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
04/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/09 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/07 and only about 1 year in 10 sees frost after that.
