When can you plant in Carney, MI?

Zone 5a

Around 05/22 is the usual last spring frost, about 267 days away. The first fall frost typically arrives around 09/27, about 126 frost-free days later.

Zone 5a (-20 to -15°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 Carney, not a forecast for this year.

What to do before the first frost

About 4 weeks of growing season left in Carney before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

How much risk comes with planting early here

05/22 is the middle of 30 years of NOAA records, not a promise. Plant by 05/07 and you're betting against frost in roughly 9 years out of 10. 06/04 is the safer bet, historically only a 1-in-10 chance of frost that late.
