Pike County, in Arkansas, sits in USDA hardiness zone 8a — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Growers here do well with cabbage, fig, california poppy, and collard greens — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Pike County lies within the Ouachita Mountains — a regional growing area with its own character.

Pike County — the short answer

Heat and winter chill in Pike County
Across a year, Pike County accumulates about 4,574 growing degree days above 50°F, about 232 fewer than the middle Arkansas county — ahead of 24 of Arkansas’s 75 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.
Winter banks about 1,725 hours below 45°F, 55 fewer than the Arkansas middle of 1,780. Chill is what tells a fruit tree its dormancy is over, and it is set by climate rather than by anything you can build.

Soil in Pike County
Across Pike County, the ground is predominantly Ultisols, where Sherless, Littlefir, and Peanutrock are the most extensive named soil series. The soil is generally well drained with a cobbly fine sandy loam surface. Topsoil pH runs about 5.0–5.5, strongly acidic. Rainfall drains through hydrologic group C soils.

How the ground varies across Pike County
The USDA soil survey maps 76% of Pike County as well drained — but another 22% drains differently: 11% moderately well drained, 6% poorly drained.
Sherless is the most extensive named soil at 23% of mapped acres, then Littlefir (13%) and Peanutrock (9%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Pike County
Each reading below is measured for Pike County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Pike County are well drained, in hydrologic group C — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Pike County runs about pH 5.0–5.5, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Season length
MeasuredPike County runs about 235 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredPike County sits in USDA hardiness zone 8a.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Pike County is in
Pike County spans 2 EPA Level III ecoregions — Ouachita Mountains (68%) and South Central Plains (32%). Which one your land falls in changes what grows wild there and how the ground behaves, and a county-wide answer cannot tell you which.
What Grows in Pike County
We scored all 1,086 plants against Pike County's own USDA zone 8a and its own 235-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Arkansas profile.
Is it too late to plant in Pike 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 Feb 22; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 22 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 12 — long-season crops need about 90 days of runway, quick greens only 30. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.

What the federal record shows across Pike County — and how to grow with it.
We checked the federal record across Pike County — 209 documented sites across 6 of the 9 source types we track.
The most significant on record: 5 Toxics Release Inventory facilities. Active industrial facilities reporting chemical releases to air, water, and land.
Pike 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.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.

What an experienced grower watches for around here
In and around Pike County, Mining runs higher than the national average — 59 sites across Pike County. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
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 soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.

Your land is one point inside Pike County
Everything above resolves to Pike County as a whole — one PHZM band and one county frost record, read across 384K acres. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at county scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better county average.

How we know this about Pike County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Pike County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Pike County
When does frost risk typically end in Pike County?
The last hard freeze (28°F) in Pike County typically lands around Mar 22, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Apr 12.
How long is the growing season in Pike County?
Measured between 28°F hard freezes, Pike County sees about 235 frost-free days — roughly Mar 22 through Nov 12, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 12 to Oct 29, about 200 days.
Is the soil safe to grow vegetables in Pike County?
The federal record around Pike County runs heavier than most — 209 documented sites, mostly Underground Storage Tanks entries (88), the nearest Mining record about 1.1 miles out — 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.
