Yes — Strong Match
Atlantic white cedar (zones 4-8) covers every zone Ohio contains (5b-7a), so hardiness is not what limits it anywhere in the state.
Your yard isn't the whole zone.
Ohio spans zones 5b-7a, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score atlantic white cedar against your parcel's actual hardiness, soil, and sun.

When to Plant Atlantic White Cedar in Ohio
The frost window
Across Ohio, the last spring hard freeze (28°F) clears between Apr 5 and Apr 13, and the first fall hard freeze lands between Oct 31 and Nov 6 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 201-day window you can count on — up to 215 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Winter standing
Ohio runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for atlantic white cedar, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether atlantic white cedar is a permanent planting or a replant-every-spring crop for you turns on your own zone within Ohio; check its hardiness range against that before treating it as long-lived ground.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says atlantic white cedar survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Atlantic White Cedar wants 140+ frost-free days; a typical Ohio site sees ~208 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Atlantic White Cedar prefers acidic soil (pH 3.5-5.5). Ohio's glacial till can run on the acidic side, which often aligns well — confirm with a soil test before planting. It will grow across that whole span, but it does best between pH 4 and 5.5 — worth knowing before you decide whether a Ohio soil test result is a problem or just a number. Drainage requirement: poorly (saturated >50% of year). A soil-survey lookup (NRCS SSURGO) flags whether your specific site matches.

Atlantic White Cedar in Ohio — Quick Answer

- Plant Zones: 4-8 (USDA PLANTS Database)
- State Zones: 5b-7a (USDA ARS PHZM 2023)

What Else to Consider for Atlantic White Cedar in Ohio
Zone compatibility tells you about winter cold survival — but Ohio growers also need to think about:
Heavy clay soils across much of northern Ohio require amendment for drainage
Variable spring weather with late frost risk through mid-May
Japanese beetles and tomato hornworms are common garden pests
Wet springs can delay planting and promote root rot
What to actually do about these — and the constraints that apply to every Ohio grower, not just atlantic white cedar — is covered on the Ohio growing guide.
Timing shifts within Ohio
Atlantic White Cedar needs about 140 days of frost-free season to complete its cycle. Even Columbiana County — Ohio’s shortest season at 182 frost-free days — clears that by 42 days, so season length isn’t the constraint anywhere in Ohio. What varies is your own parcel.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Atlantic White Cedar's 140-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Ohio Fits Best
Even within Ohio's zones 5b-7a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for atlantic white cedar (USDA PHZM 2023):
Ohio Cooperative Extension
For Ohio-specific cultivar recommendations, planting calendars, and pest pressure for atlantic white cedar, the canonical source is Ohio State University Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Atlantic White Cedar native to Ohio?
Atlantic White Cedar is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Ohio. It can still earn a place in a Ohio garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Atlantic White Cedar in Ohio
When can I plant Atlantic White Cedar in Ohio?
Ohio's last spring hard freeze (28°F) clears between Apr 5 and Apr 13, and the first fall hard freeze lands between Oct 31 and Nov 6 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Atlantic White Cedar, so this page does not state whether it overwinters in Ohio and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Atlantic White Cedar grown in across Ohio?
Ohio spans USDA hardiness zones 5b-7a (USDA ARS PHZM 2023). Atlantic White Cedar carries a range of zones 4-8, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Ohio site have?
A typical Ohio site sees ~208 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Atlantic White Cedar needs 140+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Atlantic White Cedar native to Ohio?
Atlantic White Cedar is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Ohio. It can still earn a place in a Ohio garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Atlantic White Cedar in Ohio?
Atlantic White Cedar prefers pH 3.5-5.5 and poorly (saturated >50% of year) drainage (Growable Ground Plant Database). Most Ohio soils run mildly acidic to neutral; many sites land near this band naturally, and a soil test plus targeted sulfur or organic amendment closes any gap.
