Floyd County, in Texas, sits in USDA hardiness zone 7b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Crops well matched to these conditions include cabbage, prickly pear, california poppy, and collard greens — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Floyd County lies within the Texas High Plains / Panhandle and the High Plains — a regional growing area with its own character.

Heat and winter chill in Floyd County
Across a year, Floyd County accumulates about 4,390 growing degree days above 50°F, about 1,434 fewer than the middle Texas county — ahead of 26 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 2,005 hours below 45°F, 910 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 Floyd County
Across Floyd County, the ground is predominantly Mollisols, where Pullman, Olton, and Lofton are the most extensive named soil series. The soil is generally well drained with a clay loam surface. Topsoil pH runs about 7.3, neutral. Rainfall drains through hydrologic group C soils.

How the ground varies across Floyd County
The USDA soil survey maps 90% of Floyd County as well drained — but another 10% drains differently: 5% moderately well drained, 4% poorly drained.
Pullman is the most extensive named soil at 70% of mapped acres, then Olton (6%) and Lofton (5%).
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 Floyd County
Each reading below is measured for Floyd 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 Floyd 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 Floyd County runs about pH 7.3, 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
MeasuredFloyd County runs about 226 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
MeasuredFloyd County sits in USDA hardiness zone 7b.
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 Floyd County is in
Floyd County spans 2 EPA Level III ecoregions — High Plains (90%) and Southwestern Tablelands (10%). 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 Floyd County
We scored all 1,086 plants against Floyd County's own USDA zone 7b and its own 226-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 Floyd 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 Mar 2; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 30 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 11 — long-season crops need about 90 days of runway, quick greens only 30. Here the season winds down slowly: late sowings, a real autumn harvest, and garlic in the ground before the first hard freeze.
What gets applied to farmland in Floyd County
USGS estimates 366,026 lb of Glyphosate on Floyd County farmland in 2019, its largest by weight, ahead of Dicamba (137,711 lb) and 2,4-d (99,308 lb).

What the federal record shows across Floyd County — and how to grow with it.
We checked the federal record across Floyd County — 55 documented sites across 5 of the 9 source types we track.
The most significant on record: 1 Toxics Release Inventory facility. Active industrial facilities reporting chemical releases to air, water, and land.
The federal record across Floyd 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Floyd County, Underground Storage Tanks runs higher than the national average — 49 sites across Floyd County. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Floyd County
Everything above resolves to Floyd County as a whole — one PHZM band and one county frost record, read across 635K 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 Floyd 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 Floyd County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Floyd County
When does frost risk typically end in Floyd County?
The last hard freeze (28°F) in Floyd County typically lands around Mar 30, 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 20.
How long is the growing season in Floyd County?
Measured between 28°F hard freezes, Floyd County sees about 226 frost-free days — roughly Mar 30 through Nov 11, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 20 to Oct 28, about 191 days.
Is the soil safe to grow vegetables in Floyd County?
The federal record around Floyd County shows 55 documented sites, mostly Underground Storage Tanks entries (49), the nearest Underground Storage Tanks 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.
