61654, near Norwood, IL: the frost window

Zone 6a

The last spring frost here typically falls around 04/16, about 231 days from today. Fall's first freeze usually shows up around 10/23, roughly 189 days after the last spring frost.

Stretching the season past the first frost

Norwood's growing season runs out in roughly 8 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 04/16 isn't a guarantee

04/16 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/02 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/04 and only about 1 year in 10 sees frost after that.
