When can you plant in Grandview Heights, OH?
Around 04/20 is the usual last spring frost, about 235 days away. The first fall frost typically arrives around 10/24, about 185 frost-free days later.
The USDA Plant Hardiness Zone Map puts Grandview Heights in Zone 6b (-5 to 0°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Why 04/20 isn't a guarantee
04/20 is the middle of 30 years of NOAA records, not a promise. Plant by 04/05 and you're betting against frost in roughly 9 years out of 10. 05/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
