What are the 3 USDA Planting Zones in Eastern Ohio?
Eastern Ohio locations span three USDA hardiness zones from 6a to 7a, with winter temperatures ranging from -10°F to 5°F (-23.3°C to -15.0°C). The 8 primary locations in Eastern Ohio’s USDA planting zones are Bellaire, Cadiz, East Liverpool, East Palestine, Lisbon, St Clairsville, Steubenville area, and Toronto, listed below.
1. Zone 6b and 7a in Bellaire
Bellaire lies in USDA planting zones 6b and 7a where winter minimum temprature range is -5°F to 5°F (-20.6°C to -15.0°C). The city’s position along the Ohio River at 650-750 feet elevation generates moderating climate.
The river’s thermal mass prevents temperature extremes, creating zone 7a conditions in Bellaire protected valleys and the exposed slopes remain in zone 6b.
American sycamores (Platanus occidentalis), tulip trees (Liriodendron tulipifera), and white oaks (Quercus alba) thrive here.
2. Zone 6b in Cadiz
Cadiz is entirely in USDA planting zone 6b, where winter temperatures reach -5°F to 0°F (-20.6°C to -17.8°C).
Cadiz’s elevated position at 1,165 feet in Harrison County generates cooler microclimates, and nearby Clendening and Tappan Lakes provide thermal mass that moderates temperature extremes.
Eastern red cedars (Juniperus virginiana), American beech (Fagus grandifolia), and tulip trees (Liriodendron tulipifera) grows well in zone 6b landscape.
3. Zone 6b and 7a in East Liverpool
East Liverpool of Ohio lies in USDA planting zones 6b and 7a, experiencing winter minimums from -5°F to 5°F (-20.6°C to -15.0°C).
The city’s location along the Ohio River creates thermal moderation, due to which nearby areas have warmer 7a zone and inland areas remain in zone 6b.
4. Zone 6a and 6b in East Palestine
East Palestine of ohio lies in USDA planting zones 6a and 6b, experiencing winter lows between -10°F to 0°F (-23.3°C to -17.8°C).
The village’s 1,040-foot elevation and border position between Ohio and Pennsylvania creates transitional microclimates influenced by the Ohio River Watershed. Annual temperatures here span 20°F to 83°F (-6.7°C to 28.3°C).
Eastern white pine (Pinus strobus), American beech (Fagus grandifolia), and sugar maple (Acer saccharum) are suitable for zones 6a-6b conditions
5. Zones 6a and 6b in Lisbon
Lisbon in Ohio occupies zones 6a and 6b with winter minimums ranging -10°F to 0°F (-23.3°C to -17.8°C).
Lisbon’s 1,014-foot elevation in the Appalachian foothills, combined with its location along Little Beaver Creek, generates continental climate effects that maintain these colder growing zones conditions.
Sugar maples (Acer saccharum), eastern white pines (Pinus strobus), and northern red oaks (Quercus rubra) flourish in Lisbon’s zones 6a-6b.
6. Zone 6b in St. Clairsville
St. Clairsville of Ohio occupies USDA planting zone 6b, experiencing winter minimums of -5°F to 0°F (-20.6°C to -17.8°C).
St. Clairsville’s elevated position at 1,224 feet in eastern Ohio’s Appalachian foothills generates cold air drainage and thermal stability. This hilltop microclimate provides protection from extreme temperature maintaining consistent zone 6b hardiness conditions.
Eastern red cedars (Juniperus virginiana), white oaks (Quercus alba), and sugar maples (Acer saccharum) flourish in St. Clairsville’s zone 6b environment.
7. Zone 6b and 7a in Steubenville
Steubenville in ohio lies in USDA planting zones 6b and 7a, where winter temperatures reach -5°F to 5°F (-20.6°C to -15.0°C). The city’s location along the Ohio River at 1,050-1,132 feet elevation creates these two distinct zones conditions.
River proximity provides thermal mass effects, generating 2-3°F temperature increases in valley areas which results in USDA zone 7a, and the higher elevations areas remains in USDA 6b.
Eastern red cedars (Juniperus virginiana), American sycamores (Platanus occidentalis), and tulip do well here.
8. Zone 6b and 7a in Toronto
Toronto in Ohio occupies USDA planting zones 6b and 7a, with winter minimums between -5°F to 5°F (-20.6°C to -15.0°C).
Toronto’s Ohio River location creates thermal mass effects moderating winter temperatures, which creates zone 7a, and the 738-foot elevation results in zone 6b conditions in upper areas.
Eastern red cedars (Juniperus virginiana), American sycamores (Platanus occidentalis), and tulip trees (Liriodendron tulipifera) thrive in Toronto’s 6b and 7a USDA zones.
