Bellevue, MI 49021 Frost Dates

Zone 6a (-10 to -5°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Bellevue, not a forecast for this year.
What to do before the first frost
About 6 weeks of growing season left in Bellevue before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/06 isn't a guarantee
05/06 is the middle of 30 years of NOAA records, not a promise. Plant by 04/21 and you're betting against frost in roughly 9 years out of 10. 05/23 is the safer bet, historically only a 1-in-10 chance of frost that late.
