When can you plant in Coolville, OH?

Zone 6b

The last spring frost here typically falls around 04/14, about 229 days from today. The first fall frost typically arrives around 10/30, about 197 frost-free days later.

The USDA Plant Hardiness Zone Map puts Coolville in Zone 6b (-5 to 0°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 9 weeks of growing season left in Coolville before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/14 isn't a guarantee

04/14 is the middle of 30 years of NOAA records, not a promise. Plant by 03/31 and you're betting against frost in roughly 9 years out of 10. 05/02 is the safer bet, historically only a 1-in-10 chance of frost that late.
