Lagrange, IN: when does the frost end?

Zone 6a

Typically, the last spring freeze lands around 04/30, roughly 245 days out. Fall's first freeze usually shows up around 10/16, roughly 167 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 Lagrange, not a forecast for this year.

Stretching the season past the first frost

With roughly 7 weeks until Lagrange's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

The actual range around Lagrange's last frost

04/30 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/17 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/15 and only about 1 year in 10 sees frost after that.
