When can you plant in Rossville, IL?

Zone 6a

The last spring frost here typically falls around 04/22, about 237 days from today. The first fall frost typically arrives around 10/19, about 180 frost-free days later.

The USDA Plant Hardiness Zone Map puts Rossville in Zone 6a (-10 to -5°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

How much risk comes with planting early here

04/22 is the middle of 30 years of NOAA records, not a promise. Plant by 04/07 and you're betting against frost in roughly 9 years out of 10. 05/08 is the safer bet, historically only a 1-in-10 chance of frost that late.
