When can you plant in Ligonier, IN?
Around 04/24 is the usual last spring frost, about 239 days away. The first fall frost typically arrives around 10/24, about 182 frost-free days later.
The USDA Plant Hardiness Zone Map puts Ligonier 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

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