Yes — Strong Match
zoysiagrass (zones 5-10) covers every zone Arkansas contains (6b-8b), so hardiness is not what limits it anywhere in the state.

Arkansas is not one climate
Arkansas’s winter-low ladder runs across 75 counties, from zone 7 in Benton County to zone 8.5 in Union County. That is 15°F between the two counties’ average coldest night — the difference between zoysiagrass overwintering in the ground and coming under cover.
The middle half of 75 counties runs 7.5–8 zones, with a median of 8 zones — a 1.5-zone span end to end.

Where in Arkansas Fits Best
Even within Arkansas's zones 6b-8b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for zoysiagrass (USDA PHZM 2023):

When to Plant Zoysiagrass in Arkansas
The frost window
Across Arkansas, the last spring hard freeze (28°F) clears between Mar 2 and Mar 20, and the first fall hard freeze lands between Nov 15 and Nov 23 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 240-day window you can count on — up to 266 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
Arkansas runs as cold as USDA zone 6, and no sourced winter-hardiness floor is on record for zoysiagrass, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether zoysiagrass is a permanent planting or a replant-every-spring crop for you turns on your own zone within Arkansas; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Carroll County, not the statewide average.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. 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 zoysiagrass survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Zoysiagrass wants 150+ frost-free days; a typical Arkansas site sees ~254 (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
Zoysiagrass tolerates a wide pH range (pH 5-8) — 3 units, acid ground through alkaline — so soil acidity is rarely what limits it in Arkansas. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 5.5 and 6.5 — worth knowing before you decide whether a Arkansas soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells), excessive (dry/moderately dry). If your Arkansas site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
SSURGO maps about 33.9% of Arkansas as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Zoysiagrass tolerates drought well, so wet feet — not dry spells — is its real risk here — your soil map unit, not the state average, is the real answer.

What Else to Consider for Zoysiagrass in Arkansas
Zone compatibility tells you about winter cold survival — but Arkansas growers also need to think about:
Hot, humid summers drive fungal and bacterial diseases
Heavy clay soils in parts of the Ozarks
Severe spring storms and hail risk
Growing zoysiagrass here specifically
Zoysiagrass roots run medium and prefer pH 5.0–8.0, but drainage comes first here: SSURGO maps about 33.9% of Arkansas as poorly or somewhat-poorly drained, and wet ground rots its crown before pH ever matters.
Plant zoysiagrass on a raised, gravel-amended berm so water drains fast and the crown stays dry. How to handle it →
What to actually do about these — and the constraints that apply to every Arkansas grower, not just zoysiagrass — is covered on the Arkansas growing guide.
Timing shifts within Arkansas
Arkansas isn't one climate. In Carroll County, the last hard freeze (28°F) holds until about Mar 26 — roughly 16 days later than the recorded state median — so plant zoysiagrass to your county's window, not the statewide date.
Zoysiagrass needs about 150 days of frost-free season to complete its cycle. Even Benton County — Arkansas’s shortest season at 226 frost-free days — clears that by 76 days, so season length isn’t the constraint anywhere in Arkansas. 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"). Zoysiagrass's 150-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Arkansas Cooperative Extension
For Arkansas-specific cultivar recommendations, planting calendars, and pest pressure for zoysiagrass, 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 Zoysiagrass native to Arkansas?
No — the USDA PLANTS Database lists Zoysiagrass as introduced rather than native in the Lower 48, so it is not part of Arkansas's native flora. It grows here as a garden plant; pairing it with a few Arkansas natives keeps local pollinators fed too.

Common Questions About Growing Zoysiagrass in Arkansas
When can I plant Zoysiagrass in Arkansas?
Arkansas's last spring hard freeze (28°F) clears between Mar 2 and Mar 20, and the first fall hard freeze lands between Nov 15 and Nov 23 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Zoysiagrass, so this page does not state whether it overwinters in Arkansas 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 Zoysiagrass grown in across Arkansas?
Arkansas spans USDA hardiness zones 6b-8b (USDA ARS PHZM 2023). Zoysiagrass carries a range of zones 5-10, 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 ~254 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Zoysiagrass needs 150+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Carroll, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Zoysiagrass native to Arkansas?
No — the USDA PLANTS Database lists Zoysiagrass as introduced rather than native in the Lower 48, so it is not part of Arkansas's native flora. It grows here as a garden plant; pairing it with a few Arkansas natives keeps local pollinators fed too.
How should I amend the soil for Zoysiagrass in Arkansas?
Zoysiagrass tolerates pH 5-8 and well (dry spells), excessive (dry/moderately dry) drainage (FAO ECOCROP). That is a 3-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Arkansas site — amend for drainage and organic matter first.
