Borden County, in Texas, sits in USDA hardiness zone 8a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Reliable performers under these conditions include cabbage, fig, california poppy, and collard greens; what your own ground favors still comes down to its soil, sun, and drainage.

Borden County — the short answer
Borden County, Texas: USDA zone 8a, about 252 days between hard freezes, across 574K acres.

Every figure names the dataset it came from. Hard-freeze dates are county 28°F normals: light frosts run a few weeks past them, and tender transplants usually wait 2–3 weeks after the last hard freeze.

Heat and winter chill in Borden County
Across a year, Borden County accumulates about 5,331 growing degree days above 50°F, about 493 fewer than the middle Texas county — ahead of 48 of Texas’s 254 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 1,512 hours below 45°F, 417 more than the Texas middle of 1,095. 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 Borden County
Across Borden County, the ground is predominantly Mollisols, where Olton, Vernon, and Acuff are the most extensive named soil series. The soil is generally well drained with a clay loam surface. Topsoil pH runs about 7.2–8.1, slightly alkaline. Rainfall drains through hydrologic group B soils.

How the ground varies across Borden County
The USDA soil survey maps 98% of Borden County as well drained — but another 1% drains differently: 1% moderately well drained.
Olton is the most extensive named soil at 15% of mapped acres, then Vernon (15%) and Acuff (6%).
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 Borden County
Each reading below is measured for Borden 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 Borden County are well drained, in hydrologic group B — 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 Borden County runs about pH 7.2–8.1, on the alkaline side.
Many vegetables cope, but acid-lovers like blueberries struggle, and iron and manganese lock up above about pH 7.5 — leaves yellow between the veins even in rich soil.
Elemental sulfur and generous organic matter lower pH slowly for the beds that need it; test first so you add only what the soil actually calls for.
USDA NRCS SSURGO
Season length
MeasuredBorden County runs about 252 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
MeasuredBorden 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 Borden County is in
Borden County spans 2 EPA Level III ecoregions — Southwestern Tablelands (92%) and High Plains (8%). 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 Borden County
We scored all 1,086 plants against Borden County's own USDA zone 8a and its own 252-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 Texas profile.
Is it too late to plant in Borden County?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Feb 11; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 11 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 18 — long-season crops need about 90 days of runway, quick greens only 30. With a season this long, “too late” mostly means “switch crops” — second sowings and a full fall garden are the norm, with garlic closing the year.

What the federal record shows across Borden County — and how to grow with it.
We checked the federal record across Borden County — 6 documented sites across 1 of the 9 source types we track.
The most significant on record: 6 underground storage tanks. Registered underground fuel tanks — the #1 source of soil contamination in residential areas.
The federal record across Borden County is light. Growing food here starts from a strong position — a quick pass over the map tells you whether any recorded site sits near your land, and if one does, that's information to plant with, not a reason to stop.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.

Your land is one point inside Borden County
Everything above resolves to Borden County as a whole — one PHZM band and one county frost record, read across 574K 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 Borden 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 Borden County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Borden County
When does frost risk typically end in Borden County?
The last hard freeze (28°F) in Borden County typically lands around Mar 11, 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 1.
How long is the growing season in Borden County?
Measured between 28°F hard freezes, Borden County sees about 252 frost-free days — roughly Mar 11 through Nov 18, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 1 to Nov 4, about 217 days.
Is the soil safe to grow vegetables in Borden County?
The federal record around Borden County is light — 6 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (6), the nearest Underground Storage Tanks record about 0.6 miles out — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
