4 Planting Zones in Ohio with Map

What Zone is Ohio?

Ohio has 4 planting zones: Zone 5b, Zone 6a, Zone 6b, and Zone 7a, as per the latest 2023 USDA Plant Hardiness Zones data.

Planting zones, also known as USDA Plant Hardiness Zones, help determine which plants are most likely to thrive in specific areas based on its average annual minimum winter temperatures.

You can find your Ohio planting zone by using our ZIP code tool or the Ohio city planting zone map. Both tools, provided below in the post, will help you determine your exact USDA growing zone.

What are the 4 Planting Zones of Ohio?

Northeast Ohio, is primarily in Zone 6a but also includes Zone 6b and 7a, for example Clevaland is mainly in Zone 6b but regions close to Lake Erie falls in zone 7a.

Northwest Ohio is mainly Zone 6a, for example Montpelier is in Zone 6a, but also includes Zone 6b such as Toledo falls within Zone 6b.

Northern Ohio is majorly in Zone 6a, for example Mansfield is in Zone 6a. But some Upper Norther Ohio areas lies in Zone 6b, like Sandusky is in Zone 6b.

Southern Ohio is mostly in Zone 6b such as Cincinnati and Chillicothe, but extreme southern Ohio lies in Zone 7a for example Portsmouth and Ironton are in Zone 7a.

Southwest Ohio is all in Zone 6b for example Dayton. Southeast Ohio is also all in Zone 6b like Athens and Marietta.

1. Zone 5b

This zone now covers only a small portion of northern Ohio, primarily in the Knox county of the state. It represents the coldest areas in Ohio, with average annual minimum temperatures ranging from -15°F to -10°F (-26.1°C to -23.3°C). Plants grown here need to be particularly cold-hardy.

2. Zone 6a

Shown in dark blue on the map above, this zone covers most of northern Ohio, including cities like Yorkshire and Lima, and extends into parts of central Ohio. This zone encompasses a significant portion of the state, with average annual minimum temperatures between -10°F to -5°F (-23.3°C to -20.6°C). This zone allows for a wider variety of plants compared to 5b but still requires cold-tolerant species.

3. Zone 6b

Depicted in light green in the map above, this zone covers the majority of central and southern Ohio, including Columbus and much of the eastern part of the state. With average annual minimum temperatures from -5°F to 0°F (-20.6°C to -17.8°C), Zone 6b offers more flexibility in plant choices and a slightly longer growing season than 6a.

4. Zone 7a

Represented by yellow areas on the map, this warmest zone in Ohio is found in pockets of the southern part of the state, particularly along the Ohio River. Its average annual minimum temperatures range from 0°F to 5°F (-17.8°C to -15°C), allowing for the cultivation of less cold-hardy plants and potentially earlier planting dates for some crops. Major cities in Zone 7a include Avon Lake, Chesapeake and Colerain.

Changes in Ohio’s planting zones Overtime?

The 2023 USDA Planting Zones Map shows notable changes across the Ohio. Most of Ohio has transitioned from Zone 6a to the warmer Zone 6b now. The “donut hole” of Zone 5b in central Ohio has largely disappeared, with only a small area remaining in northeastern Knox County. This warming trend is consistent with the overall national pattern, where about half of the USA has shifted to a warmer half-zone.
