La Moille, IL 61374 Frost Dates

When can you plant in La Moille, IL?

Zone 5b

Around 04/24 is the usual last spring frost, about 239 days away. The first fall frost typically arrives around 10/14, about 172 frost-free days later.

The USDA Plant Hardiness Zone Map puts La Moille in Zone 5b (-15 to -10°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

About 7 weeks of growing season left in La Moille before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/24 isn't a guarantee

04/24 is the middle of 30 years of NOAA records, not a promise. Plant by 04/10 and you're betting against frost in roughly 9 years out of 10. 05/09 is the safer bet, historically only a 1-in-10 chance of frost that late.
