Montezuma, OH 45866 Frost Dates
When can you plant in Montezuma, OH?
Around 04/27 is the usual last spring frost, about 242 days away. The first fall frost typically arrives around 10/19, about 175 frost-free days later.
The USDA Plant Hardiness Zone Map puts Montezuma 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
About 7 weeks of growing season left in Montezuma before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/27 isn't a guarantee
04/27 is the middle of 30 years of NOAA records, not a promise. Plant by 04/12 and you're betting against frost in roughly 9 years out of 10. 05/10 is the safer bet, historically only a 1-in-10 chance of frost that late.
