Is it too late to plant in Garland 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 8; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 5 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 22 — 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.

Frequently Asked Questions
What hardiness zone is Garland County, Arkansas?
Garland 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 Garland 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 8; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 5 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 22 — 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 Garland County?
The last hard freeze (28°F) in Garland County typically lands around Feb 5, 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 Garland County?
Measured between 28°F hard freezes, Garland County sees about 320 frost-free days — roughly Feb 5 through Dec 22, 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 Garland County?
Garland 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 Garland County, really?
Officially, Garland 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 Garland County?
The federal record around Garland County is a meaningful one — 439 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 Garland County — what should I know before planting?
Start with three facts. Garland County sits in USDA zone 8a, which sets what survives winter; the last 28°F hard freeze typically clears around Feb 5, with about 320 frost-free days to work with (NOAA 1991–2020 climate normals); and 439 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.
