Conditional — Some Areas
eastern red cedar (zones 3-9) has limited zone overlap with Vermont (3b-5b). Only zones 3-5 in the state are suitable.
Your yard isn't the whole zone.
Vermont spans zones 3b-5b, 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 Vermont
The frost window
Across Vermont, the last spring frost clears between May 5 and Jun 1, and the first fall frost lands between Sep 10 and Oct 5 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 101-day window you can count on — up to 153 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 Vermont'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 Vermont site sees ~150 (NOAA Climate Normals). That leaves comfortable headroom for succession planting.
Chill hours
Eastern Red Cedar requires ~800 chill hours (32-45°F dormancy window). Vermont typically banks ~1650 chill hours per winter (MSU Extension method), which keeps this plant on track.
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 Vermont's glacial till and clay — a soil test confirms it for your site.

Eastern Red Cedar in Vermont — Quick Answer
- Verdict: Conditional — Some Areas
- Plant Zones: 3-9 (USDA PLANTS Database)
- State Zones: 3b-5b (USDA ARS PHZM 2023)
- Growing Season: May 5 - Jun 1 to Sep 10 - Oct 5 (NOAA Climate Normals)
What Else to Consider
Zone compatibility tells you about winter cold survival — but Vermont growers also need to think about:
Short growing season (100-130 frost-free days)
Indoor starts, fast varieties, and a cold frame on each shoulder — the Vermont formula for making 110 days feel like 150.
Rocky soils throughout the Green Mountains
Raised beds spare you the stone harvest — build up over cleared ground and plant the same weekend.
Heavy clay in the Champlain Valley
Champlain clay holds spring water late — raised or mounded beds dry out and warm up weeks earlier for planting.
Vermont Cooperative Extension
For Vermont-specific cultivar recommendations, planting calendars, and pest pressure for eastern red cedar, the canonical source is UVM Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Eastern Red Cedar native to Vermont?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Eastern Red Cedar as native to Vermont. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Eastern Red Cedar in Vermont
When can I plant Eastern Red Cedar in Vermont?
Vermont's last spring frost clears between May 5 and Jun 1, and the first fall frost lands between Sep 10 and Oct 5 (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 Vermont?
Vermont spans USDA hardiness zones 3b-5b (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 Vermont site have?
A typical Vermont site sees ~150 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 Vermont?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Eastern Red Cedar as native to Vermont. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Eastern Red Cedar in Vermont?
Eastern Red Cedar prefers pH 4.7-8 (USDA PLANTS Database). That sits in the common-ground band across Vermont 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 Vermont?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores eastern red cedar against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
