Sharp County, in Arkansas, sits in USDA hardiness zone 7b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Reliable performers under these conditions include tomato, peach, muscadine grape, and sweet potato; what your own ground favors still comes down to its soil, sun, and drainage.
Sharp County lies within the Ozarks — a regional growing area with its own character.

Soil in Sharp County
Across Sharp County, the ground is predominantly Alfisols, where Gepp, Boden, and Doniphan are the most extensive named soil series. The soil is generally well drained with a very gravelly silt loam surface. Topsoil pH runs about 5.0–5.8, strongly acidic. Rainfall drains through hydrologic group D soils.

Is it too late to plant in Sharp County?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Jan 24; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 21 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 7 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.

Growing Challenges in Arkansas
What an experienced grower plans around here — each one has a move.

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.

Safe to Grow Here?
What the federal record shows across Sharp County — and how to grow with it.
We checked the federal record across Sharp County — 98 documented sites across 5 of the 9 source types we track.
The most significant on record: 15 mining sites. Historic and active mines that may leach heavy metals like arsenic, lead, and cadmium.
There's a meaningful federal record across Sharp County — worth a look before you plant food, not a reason to hold back from growing. Proximity to a documented site is information, not a diagnosis of any one yard. A soil test before new food beds is the sensible precaution here, and the map shows exactly which sites sit where, so you can see what's actually near you.

A note from Gnorman
What an experienced grower watches for around here
In and around Sharp County, two things run higher than the national average — Mining (15 sites) and Underground Storage Tanks (61 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Frequently Asked Questions
What hardiness zone is Sharp County, Arkansas?
Sharp County sits in USDA hardiness zone 7b, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.
Is it too late to plant in Sharp County?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Jan 24; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 21 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 7 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.
When does frost risk typically end in Sharp County?
The last hard freeze (28°F) in Sharp County typically lands around Feb 21, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.
How long is the growing season in Sharp County?
Measured between 28°F hard freezes, Sharp County sees about 289 frost-free days — roughly Feb 21 through Dec 7, per NOAA 1991–2020 climate normals. Tender crops get a somewhat shorter practical window, since lighter frosts reach a few weeks past the hard-freeze dates on both ends.
What vegetables grow in Sharp County?
Sharp County's zone 7b supports a wide range — strong performers include Tomato, Peach, Muscadine Grape, Sweet Potato, and Blackberry. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.
Which hardiness zone is Sharp County, really?
Officially, Sharp County sits in USDA zone 7b (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.
Is the soil safe to grow vegetables in Sharp County?
The federal record around Sharp County is a meaningful one — 98 documented sites — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
Just moved to Sharp County — what should I know before planting?
Start with three facts. Sharp County sits in USDA zone 7b, which sets what survives winter; the last 28°F hard freeze typically clears around Feb 21, with about 289 frost-free days to work with (NOAA 1991–2020 climate normals); and 98 documented sites sit on the federal record here, so a soil test before food beds is the smart first step. From there, matching plants to your actual soil and sun is the fun part.
