Arkansas is not one climate

A single Arkansas answer averages 75 counties whose growing seasons are 58 days apart — from 226 frost-free days in Benton County to 284 in Lincoln County. Which end of that your land sits nearer changes what mint can finish before the first hard freeze.

When to Plant Mint 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.

Establishment timing

As a long-lived plant, mint isn't racing the calendar to a harvest date. Plant it in spring once the last hard-freeze window passes so roots settle in through the full season, or in early fall while the soil still holds summer warmth.

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

Mint is grown in zones 3–11, which covers every zone Arkansas contains (6b-8b). It overwinters in the ground only in zone 5 and warmer (NC State Extension Gardener Plant Toolbox). Arkansas's typical season runs ~254 frost-free days against the ~40 mint needs.

Growing degree days

Mint needs ~1500 GDD (base 50°F) to ripen. We haven't confirmed this against a published source yet. The state median runs ~4819 GDD (from PRISM 1991-2020 climate normals), so Arkansas's typical season clears that easily.

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

Mint tolerates a wide pH range (pH 4.5-8.3) — 3.8 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). If your Arkansas site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost. Drainage need: We haven't confirmed this against a published source yet.

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. Mint has low drought tolerance, so it is the fast-draining end that will cost you — your soil map unit, not the state average, is the real answer.

Before you plant mint for food

Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before mint goes in. What follows is Arkansas’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.

Safe to Grow Here?

What the federal record shows across Arkansas — and how to grow with it.

Federal record: High

We checked the federal record across Arkansas — 12,957 documented sites across 7 of the 8 source types we track.

The most significant on record: 88 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.

Arkansas carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds of imported, lab-tested soil grow well almost anywhere in the meantime.

What Else to Consider for Mint in Arkansas

The zone range tells you where mint is grown — 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 mint here specifically

Mint rates to USDA zones 3–11 and takes frost damage on growing tissue around 30°F (FAO ECOCROP), but cold isn't the risk in Arkansas — wet is: with roughly 33.9% of its soils poorly-drained (SSURGO), soggy ground rots the crown.

Give mint a raised bed or mounded row with coarse amendment so its crown never sit wet. How to handle it →

What to actually do about these — and the constraints that apply to every Arkansas grower, not just mint — 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 mint to your county's window, not the statewide date.

County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.

Where in Arkansas Mint Is Zone-Hardy

Mint is rated for USDA zones 3–11. Every one of Arkansas’s 75 counties sits inside that band — from Benton County at zone 7a to Union County at zone 8b — so winter cold is not what decides this plant anywhere in the state. What is left to vary is your own parcel: slope, shelter and cold-air drainage routinely move a site half a zone either way from the county figure.

Across those 75 counties Arkansas’s winter-low ladder runs from zone 7a in Benton County to zone 8b in Union County — 1.5 USDA zones of spread, which is 15°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.

The planting window moves with it. Carroll County holds its last hard freeze (28°F) until about Mar 26, while Chicot County is clear by Feb 19 — 35 days apart. Set mint out on your county’s date, not the state’s.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost". Mint’s zone 3–11 band: Not verified — NC State Extension Gardener Plant Toolbox lists zones 4a–9b. A parcel report resolves your address’s own zone and frost dates rather than its county’s.

Pollinator + Wildlife Value

Mint draws honeybees, native bees, and butterflies (moderate value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, mint can only work that bloom inside Arkansas's frost window — roughly 254 days, opening after the last 28°F freeze (Mar 2 - Mar 20) and closing at the first (Nov 15 - Nov 23), per NOAA Regional Climate Centers ACIS, 1991-2020. Deer pressure is meaningful across much of Arkansas; mint is listed as deer-resistant (NC State Extension Gardener Plant Toolbox), which makes it a safer pick for unfenced sites. Our deer & wildlife guide carries the full deer-resistant list and how to protect the rest. Pollinator value: We haven't confirmed this against a published source yet.

Good to Know Before You Plant Mint

Mint is listed as toxic to dogs, cats, horses. (Source: NC State Extension Gardener Plant Toolbox.) Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear. Worth knowing for placement: mint overwinters through Arkansas — its sourced hardiness floor is zone 5 and the state runs no colder than zone 6 — so it stands in the bed year-round, and where you site it is a long-term decision.

Recommended Mint Varieties for Arkansas

Arkansas publishes no state variety trial for mint, so we won't invent a "best for Arkansas" list. Choose types rated to your USDA hardiness zone (6b-8b), and confirm winter survival and drainage against your own parcel.

Arkansas Cooperative Extension

For Arkansas-specific cultivar recommendations, planting calendars, and pest pressure for mint, 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 Mint native to Arkansas?

No — the USDA PLANTS Database lists Mint 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.

Looking for plants that belong here? The Arkansas growing guide lists plants that USDA PLANTS records growing in Arkansas and that Kew and NatureServe Explorer both list in its native range, leaving out any that NatureServe flags as exotic there or that our audit holds.

Common Questions About Growing Mint in Arkansas

When can I plant Mint 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). Mint is a long-lived planting, so target spring just after your local last hard freeze — or early fall while the soil holds warmth — and let it establish through the season.

What hardiness zone is Mint grown in across Arkansas?

Arkansas spans USDA hardiness zones 6b-8b (USDA ARS PHZM 2023). Mint carries a range of zones 3-11, 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 ~254 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Mint needs 40+ 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 Mint native to Arkansas?

No — the USDA PLANTS Database lists Mint 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 Mint in Arkansas?

Mint tolerates pH 4.5-8.3 and well (dry spells) drainage. We haven't confirmed this against a published source yet. That is a 3.8-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.
