Jim Hogg County, in Texas, sits in USDA hardiness zone 9b — a zone band wide enough that plant choice, not possibility, is the interesting question.
These conditions suit okra, meyer lemon, california poppy, and artichoke — a starting list any specific site will trim or extend with its own soil, sun, and drainage.

Heat and winter chill in Jim Hogg County
Across a year, Jim Hogg County accumulates about 8,407 growing degree days above 50°F, about 2,583 more than the middle Texas county — ahead of 245 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 0 hours below 45°F, 1,095 fewer 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 Jim Hogg County
Across Jim Hogg County, the ground is predominantly Alfisols, where Nueces, Delmita, and Sarita are the most extensive named soil series. The soil is generally well drained with a fine sand surface. Topsoil pH runs about 6.5–7.2, neutral. Rainfall drains through hydrologic group B soils.

How the ground varies across Jim Hogg County
The USDA soil survey maps 60% of Jim Hogg County as well drained — but another 40% drains differently: 33% moderately well drained, 8% somewhat excessively drained.
Nueces is the most extensive named soil at 22% of mapped acres, then Delmita (20%) and Sarita (14%).
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 Jim Hogg County
Each reading below is measured for Jim Hogg 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 Jim Hogg 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 Jim Hogg County runs about pH 6.5–7.2, close to neutral.
This is the range most vegetables prefer — one correction you probably do not have to make, which is genuinely good news for a new bed.
Keep it there with compost rather than lime or sulfur, and only amend if your own soil test says otherwise.
USDA NRCS SSURGO
Season length
MeasuredJim Hogg County runs about 329 days between hard freezes — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredJim Hogg County sits in USDA hardiness zone 9b.
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 Jim Hogg County is in
Jim Hogg County spans 2 EPA Level III ecoregions — Western Gulf Coastal Plain (53%) and Southern Texas Plains (47%). 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 Jim Hogg County
We scored all 1,086 plants against Jim Hogg County's own USDA zone 9b and its own 329-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 Jim Hogg County?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Jan 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jan 25 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 20 — long-season crops need about 90 days of runway, quick greens only 30. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.
What gets applied to farmland in Jim Hogg County
USGS estimates 5,058 lb of 2,4-d on Jim Hogg County farmland in 2019, its largest by weight, ahead of Glyphosate (3,282 lb) and Triclopyr (472 lb).

What the federal record shows across Jim Hogg County — and how to grow with it.
We checked the federal record across Jim Hogg County — 43 documented sites across 5 of the 9 source types we track.
The most significant on record: 4 Toxics Release Inventory facilities. Active industrial facilities reporting chemical releases to air, water, and land.
The federal record across Jim Hogg County is a modest one — a typical footprint for a growing area. Nothing here calls for alarm; it's worth knowing which recorded sites sit closest to where you grow, and each one on the map carries its type and location. If one turns out to be a near neighbor, a one-time soil test settles the question.
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 Jim Hogg County, two things run higher than the national average across Jim Hogg County — Toxics Release Inventory (4 sites) and Underground Storage Tanks (30 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Jim Hogg County
Everything above resolves to Jim Hogg County as a whole — one PHZM band and one county frost record, read across 727K 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 Jim Hogg 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 Jim Hogg County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Jim Hogg County
When does frost risk typically end in Jim Hogg County?
The last hard freeze (28°F) in Jim Hogg County typically lands around Jan 25, 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 Feb 15.
How long is the growing season in Jim Hogg County?
Measured between 28°F hard freezes, Jim Hogg County sees about 329 frost-free days — roughly Jan 25 through Dec 20, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 15 to Dec 6, about 294 days.
Is the soil safe to grow vegetables in Jim Hogg County?
The federal record around Jim Hogg County shows 43 documented sites, mostly Underground Storage Tanks entries (30), the nearest PFAS record under a tenth of a mile out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
