Conditional — Some Areas
Osage orange (zones 5-11) has limited zone overlap with Arkansas (6b-8a). Only zones 6-8 in the state are suitable.
Your yard isn't the whole zone.
Arkansas spans zones 6b-8a, 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 osage orange against your parcel's actual hardiness, soil, and sun.

When to Plant Osage Orange in Arkansas
The frost window
Across Arkansas, the last spring frost clears between Mar 15 and Apr 15, and the first fall frost lands between Oct 15 and Nov 10 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 183-day window you can count on — up to 240 days on a mild site in a kind year.
Frost hardiness
Osage Orange is cold-hardy to -23°F (USDA PLANTS Database), so you can plant on the early side of Arkansas's window — even a few weeks before the final frost date.
Establishment timing
As a long-lived plant, osage orange 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
Osage Orange wants 180+ frost-free days; a typical Arkansas site sees ~220 (NOAA Climate Normals). That leaves a workable window — start indoors to bank time.
Chill hours
Osage Orange requires ~400 chill hours (32-45°F dormancy window). Arkansas typically banks ~900 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
Osage Orange likes near-neutral soil (pH 4.5-7.5). That's the common-ground band across Arkansas's silt loam and sandy loam — a soil test confirms it for your site.

Osage Orange in Arkansas — Quick Answer
- Verdict: Conditional — Some Areas
- Plant Zones: 5-11 (USDA PLANTS Database)

- Growing Season: Mar 15 - Apr 15 to Oct 15 - Nov 10 (NOAA Climate Normals)
What Else to Consider
Zone compatibility tells you about winter cold survival — but Arkansas growers also need to think about:
Hot, humid summers drive fungal and bacterial diseases
Morning base-watering, wide spacing, and resistant varieties keep disease manageable — your extension lists what holds up here.
Heavy clay soils in parts of the Ozarks
A raised bed gets you growing this season; compost worked in each fall opens the clay for the long run.
Severe spring storms and hail risk
Keep row cover staged through storm season — five minutes of shelter can save a bed of seedlings from hail.
Arkansas Cooperative Extension
For Arkansas-specific cultivar recommendations, planting calendars, and pest pressure for osage orange, the canonical source is University of Arkansas Cooperative Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Osage Orange native to Arkansas?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Osage Orange as native to Arkansas. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Osage Orange in Arkansas
When can I plant Osage Orange in Arkansas?
Arkansas's last spring frost clears between Mar 15 and Apr 15, and the first fall frost lands between Oct 15 and Nov 10 (NOAA Climate Normals 1991-2020). Osage Orange 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 Osage Orange grown in across Arkansas?
Arkansas spans USDA hardiness zones 6b-8a (USDA ARS PHZM 2023). Osage Orange carries a range of zones 5-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Arkansas site have?
A typical Arkansas site sees ~220 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Osage Orange needs 180+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Osage Orange native to Arkansas?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Osage Orange as native to Arkansas. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Osage Orange in Arkansas?
Osage Orange prefers pH 4.5-7.5 (USDA PLANTS Database). That sits in the common-ground band across Arkansas soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Osage Orange actually grow on my specific land in Arkansas?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores osage orange against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
