Manchester, MI 48158 Frost Dates

When can you plant in Manchester, MI?

Zone 6a

The last spring frost here typically falls around 04/30, about 245 days from today. The first fall frost typically arrives around 10/14, about 165 frost-free days later.

The USDA Plant Hardiness Zone Map puts Manchester in Zone 6a (-10 to -5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

How much risk comes with planting early here

04/30 is the middle of 30 years of NOAA records, not a promise. Plant by 04/16 and you're betting against frost in roughly 9 years out of 10. 05/16 is the safer bet, historically only a 1-in-10 chance of frost that late.
