Frost dates, planting zones, soil types, and what actually thrives in Ohio — from mountains to coast.
Frost dates & zones
Ohio spans USDA zones 5b (northern OH / Cleveland area) to 6b (southern OH / Cincinnati area). Verify your exact zone and frost dates with your county Extension office — elevation and microclimates create real variation.

Northwest OH heavy clay needs drainage tiles and gypsum. Southern OH hill soils need lime and compost. Most central OH soils are productive with minimal amendment. OSU Extension county offices provide soil testing.
Know your soil
Ohio soils are predominantly productive silt loam and clay loam — glacial deposits across most of the state. Northwest Ohio has heavy clay soils (formerly Lake Erie lake bed) that drain poorly but are extremely fertile. Southern Ohio's unglaciated hill country has thinner, more acidic soils. The Ohio River bottomlands have rich alluvial soils.
