Eastborough, KS: when does the frost end?
The last spring frost here typically falls around 04/14, about 229 days from today. Fall's first freeze usually shows up around 10/22, roughly 189 days after the last spring frost.

Stretching the season past the first frost
With roughly 8 weeks until Eastborough's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/14 isn't a guarantee
04/14 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/30 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/30 and only about 1 year in 10 sees frost after that.
