Conditional — Some Areas
eastern red cedar (zones 3-9) has limited zone overlap with Alabama (7a-9a). Only zones 7-9 in the state are suitable.
Your yard isn't the whole zone.
Alabama spans zones 7a-9a, 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 eastern red cedar against your parcel's actual hardiness, soil, and sun.

When to Plant Eastern Red Cedar in Alabama
The frost window
Across Alabama, the last spring frost clears between Feb 28 and Apr 5, and the first fall frost lands between Oct 25 and Nov 20 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 203-day window you can count on — up to 265 days on a mild site in a kind year.
Frost hardiness
Eastern Red Cedar is cold-hardy to -43°F (USDA PLANTS Database), so you can plant on the early side of Alabama's window — even a few weeks before the final frost date.
Establishment timing
As a long-lived plant, eastern red cedar isn't racing the calendar to a harvest date. Plant it in spring once the last-frost window passes so roots settle in through the full season, or in early fall while the soil still holds summer warmth.
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
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Eastern Red Cedar wants 0+ frost-free days; a typical Alabama site sees ~220 (NOAA Climate Normals). That leaves comfortable headroom for succession planting.
Chill hours
Eastern Red Cedar requires ~800 chill hours (32-45°F dormancy window). Alabama typically banks ~600 chill hours per winter, short of this plant's requirement — fruit set may suffer in mild years without a low-chill cultivar.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Eastern Red Cedar likes near-neutral soil (pH 4.7-8). That's the common-ground band across Alabama's red clay and sandy loam — a soil test confirms it for your site.

What Else to Consider
Zone compatibility tells you about winter cold survival — but Alabama growers also need to think about:
Heavy clay soils in the Piedmont region
Open clay with compost over time — or start above it in a raised bed and let the ground catch up underneath.
High humidity promotes fungal diseases
Airflow is the free fungicide: space generously, water at the base in the morning, and pick resistant varieties from your extension's list.
Fire ants are a persistent garden pest
Season-long baiting beats mound-by-mound whack-a-mole — your extension office publishes the current program that works.
Alabama Cooperative Extension
For Alabama-specific cultivar recommendations, planting calendars, and pest pressure for eastern red cedar, the canonical source is Alabama Cooperative Extension System. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Eastern Red Cedar native to Alabama?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Eastern Red Cedar as native to Alabama. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Eastern Red Cedar in Alabama
When can I plant Eastern Red Cedar in Alabama?
Alabama's last spring frost clears between Feb 28 and Apr 5, and the first fall frost lands between Oct 25 and Nov 20 (NOAA Climate Normals 1991-2020). Eastern Red Cedar is a long-lived planting, so target spring just after your local last frost — or early fall while the soil holds warmth — and let it establish through the season.
What hardiness zone is Eastern Red Cedar grown in across Alabama?
Alabama spans USDA hardiness zones 7a-9a (USDA ARS PHZM 2023). Eastern Red Cedar carries a range of zones 3-9, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Alabama site have?
A typical Alabama site sees ~220 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Eastern Red Cedar needs 0+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Eastern Red Cedar native to Alabama?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Eastern Red Cedar as native to Alabama. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Eastern Red Cedar in Alabama?
Eastern Red Cedar prefers pH 4.7-8 (USDA PLANTS Database). That sits in the common-ground band across Alabama soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Eastern Red Cedar actually grow on my specific land in Alabama?
