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.

What the federal record shows across Pulaski County — and how to grow with it.
We checked the federal record across Pulaski County — 2,066 documented sites across 7 of the 9 source types we track.
The most significant on record: 10 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Pulaski 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.

Frequently Asked Questions
What hardiness zone is Pulaski County, Arkansas?
Pulaski 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.
When does frost risk typically end in Pulaski County?
The last hard freeze (28°F) in Pulaski County typically lands around Jan 28, 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.
What vegetables grow in Pulaski County?
Pulaski 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 Pulaski County, really?
Officially, Pulaski 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 Pulaski County?
The federal record around Pulaski County runs heavier than most — 2,066 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 Pulaski County — what should I know before planting?
Start with three facts. Pulaski County sits in USDA zone 8a, which sets what survives winter; the statewide frost window runs about Mar 15 - Apr 15 to Oct 15 - Nov 10 (NOAA 30-year climate normals); and 2,066 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.
