When can you plant in Mecosta, MI?
Around 05/13 is the usual last spring frost, about 258 days away. The first fall frost typically arrives around 10/02, about 142 frost-free days later.
The USDA Plant Hardiness Zone Map puts Mecosta in Zone 5b (-15 to -10°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
About 5 weeks of growing season left in Mecosta before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/13 isn't a guarantee
05/13 is the middle of 30 years of NOAA records, not a promise. Plant by 04/28 and you're betting against frost in roughly 9 years out of 10. 05/28 is the safer bet, historically only a 1-in-10 chance of frost that late.
