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 eggplant can finish before the first hard freeze.
The middle half of 75 counties runs 241–266 days, with a median of 254 days — a 58-day span end to end.

When to Plant Eggplant 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.
When to start the seed
Those dates are when eggplant goes out, not when it starts. It is sown under cover about 9 weeks ahead, so counting back from Arkansas's late-side last freeze of Mar 20 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.
Grown as an annual here
Eggplant is a true perennial in its home range — it overwinters from USDA zone 9 and warmer (NC State Extension Gardener Plant Toolbox) — but Arkansas runs as cold as zone 6, so it is killed back each winter and replanted each spring. Treat it on the season schedule above, not as a permanent planting: there is no fall establishment window for it here.
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
Eggplant is grown in zones 2–12, which covers every zone Arkansas contains (6b-8b). It overwinters in the ground only in zone 9 and warmer (NC State Extension Gardener Plant Toolbox). Arkansas's typical season runs ~254 frost-free days against the ~70 eggplant needs.
Growing degree days
Eggplant needs ~2400 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
Eggplant tolerates a wide pH range (pH 4.3-8.5) — 4.2 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 6.8 — 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.

Before you plant eggplant 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 eggplant 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.
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 Eggplant in Arkansas
The zone range tells you where eggplant 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
What to actually do about these — and the constraints that apply to every Arkansas grower, not just eggplant — is covered on the Arkansas growing guide.
Where in Arkansas Eggplant Is Zone-Hardy
Eggplant is rated for USDA zones 2–12. 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 eggplant 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". Eggplant’s zone 2–12 band: Not verified — NC State Extension Gardener Plant Toolbox lists zones 9a–12b. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Pollinator + Wildlife Value
Eggplant draws native bees (moderate value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, eggplant 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. Pollinator value: We haven't confirmed this against a published source yet.
Arkansas Cooperative Extension
For Arkansas-specific cultivar recommendations, planting calendars, and pest pressure for eggplant, 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 Eggplant native to Arkansas?
No — the USDA PLANTS Database lists Eggplant 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 Eggplant in Arkansas
When can I plant Eggplant 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). Eggplant overwinters only from USDA zone 9 and warmer, and Arkansas runs as cold as zone 6, so it is grown as an annual here — plant it after the last hard freeze, two to three weeks later for tender stock, and expect to replant next spring rather than establishing it for the long term.
What hardiness zone is Eggplant grown in across Arkansas?
Arkansas spans USDA hardiness zones 6b-8b (USDA ARS PHZM 2023). Eggplant carries a range of zones 2-12, 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). Eggplant needs 70+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Eggplant native to Arkansas?
No — the USDA PLANTS Database lists Eggplant 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 Eggplant in Arkansas?
Eggplant tolerates pH 4.3-8.5 and well (dry spells) drainage (FAO ECOCROP). That is a 4.2-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.
