Findlay, OH 45840 Frost Dates
Findlay, OH: when does the frost end?
Around 04/19 is the usual last spring frost, about 234 days away. Fall's first freeze usually shows up around 10/23, roughly 185 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Findlay in Zone 6b (-5 to 0°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost

How much risk comes with planting early here
04/19 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/05 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/06 and only about 1 year in 10 sees frost after that.
