When can you plant in North Liberty, IN?
Around 04/19 is the usual last spring frost, about 234 days away. The first fall frost typically arrives around 10/27, about 191 frost-free days later.
The USDA Plant Hardiness Zone Map puts North Liberty in Zone 6a (-10 to -5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Why 04/19 isn't a guarantee
04/19 is the middle of 30 years of NOAA records, not a promise. Plant by 04/05 and you're betting against frost in roughly 9 years out of 10. 05/03 is the safer bet, historically only a 1-in-10 chance of frost that late.
