Bloomingdale, IN 47832 Frost Dates
When can you plant in Bloomingdale, IN?
Around 04/30 is the usual last spring frost, about 245 days away. The first fall frost typically arrives around 10/12, about 164 frost-free days later.
The USDA Plant Hardiness Zone Map puts Bloomingdale 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 04/30 isn't a guarantee
04/30 is the middle of 30 years of NOAA records, not a promise. Plant by 04/14 and you're betting against frost in roughly 9 years out of 10. 05/15 is the safer bet, historically only a 1-in-10 chance of frost that late.
