When can you plant in Andover, OH?

Zone 6a

The last spring frost here typically falls around 04/30, about 245 days from today. The first fall frost typically arrives around 10/23, about 177 frost-free days later.

Zone 6a (-10 to -5°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 Andover, not a forecast for this year.

About 8 weeks of growing season left in Andover 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

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. 05/17 is the safer bet, historically only a 1-in-10 chance of frost that late.
