Is it too late to plant in Lawrence County?

Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Jan 17; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 14 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 14 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

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 Lawrence County — and how to grow with it.

Federal record: High

We checked the federal record across Lawrence County172 documented sites across 7 of the 9 source types we track.

The most significant on record: 1 Superfund site. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.

Lawrence County 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 with clean imported soil grow well almost anywhere in the meantime.

What an experienced grower watches for around here

In and around Lawrence County, two things run higher than the national average — PFAS (4 sites) and Mining (23 sites). That's not a problem with your land — it's information about it.

PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.

Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.

Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.

Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.

Frequently Asked Questions

What hardiness zone is Lawrence County, Arkansas?

Lawrence County sits in USDA hardiness zone 8a, 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 Lawrence County?

Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Jan 17; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 14 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 14 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

When does frost risk typically end in Lawrence County?

The last hard freeze (28°F) in Lawrence County typically lands around Feb 14, 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 Lawrence County?

Measured between 28°F hard freezes, Lawrence County sees about 303 frost-free days — roughly Feb 14 through Dec 14, 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 Lawrence County?

Lawrence County's zone 8a 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 Lawrence County, really?

Officially, Lawrence County sits in USDA zone 8a (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 Lawrence County?

The federal record around Lawrence County runs heavier than most — 172 documented sites — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.

Just moved to Lawrence County — what should I know before planting?

Start with three facts. Lawrence County sits in USDA zone 8a, which sets what survives winter; the last 28°F hard freeze typically clears around Feb 14, with about 303 frost-free days to work with (NOAA 1991–2020 climate normals); and 172 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.

Everything on this page is a Lawrence County average. Your yard writes its own version — we read soil, sun, drainage, and frost at your exact address. Try it for 14 days — no card required.
