Moore County, in Texas, sits in USDA hardiness zone 7a — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Reliable performers under these conditions include cabbage, hazelnut, california poppy, and collard greens; what your own ground favors still comes down to its soil, sun, and drainage.

Heat and winter chill in Moore County
Across a year, Moore County accumulates about 4,021 growing degree days above 50°F, about 1,803 fewer than the middle Texas county — ahead of 10 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 2,443 hours below 45°F, 1,348 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 Moore County
Across Moore County, the ground is predominantly Mollisols, where Sherm, Sunray, and Mobeetie are the most extensive named soil series. The soil is generally well drained with a silty clay loam surface. Topsoil pH runs about 7.2–8.0, slightly alkaline. Rainfall drains through hydrologic group C soils.

How the ground varies across Moore County
The USDA soil survey maps 95% of Moore County as well drained — but another 4% drains differently: 2% somewhat excessively drained, 2% excessively drained.
Sherm is the most extensive named soil at 48% of mapped acres, then Sunray (9%) and Mobeetie (8%).
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 Moore County
Each reading below is measured for Moore 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 Moore 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 Moore County runs about pH 7.2–8.0, 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
MeasuredMoore County runs about 215 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
MeasuredMoore County sits in USDA hardiness zone 7a.
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 Moore County is in
Moore County spans 2 EPA Level III ecoregions — High Plains (66%) and Southwestern Tablelands (34%). 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 Moore County
We scored all 1,086 plants against Moore County's own USDA zone 7a and its own 215-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 Moore County?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Mar 6; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 3 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 4 — 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 gets applied to farmland in Moore County
USGS estimates 160,520 lb of Glyphosate on Moore County farmland in 2019, its largest by weight, ahead of Atrazine (108,802 lb) and Metolachlor & Metolachlor-s (66,400 lb).

What the federal record shows across Moore County — and how to grow with it.
We checked the federal record across Moore County — 169 documented sites across 7 of the 9 source types we track.
The most significant on record: 1 Superfund site (none NPL-listed). Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
There's a meaningful federal record across Moore County — worth a look before you plant food, not a reason to hold back from growing. Proximity to a documented site is information, not a diagnosis of any one yard. A soil test before new food beds is the sensible precaution here, and the map shows exactly which sites sit where, so you can see what's actually near you.
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 Moore County, CAFO runs higher than the national average — 15 sites across Moore County. That's not a problem with your land — it's information about it.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.

Your land is one point inside Moore County
Everything above resolves to Moore County as a whole — one PHZM band and one county frost record, read across 576K 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 Moore 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 Moore County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Moore County
When does frost risk typically end in Moore County?
The last hard freeze (28°F) in Moore County typically lands around Apr 3, 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 24.
How long is the growing season in Moore County?
Measured between 28°F hard freezes, Moore County sees about 215 frost-free days — roughly Apr 3 through Nov 4, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 24 to Oct 21, about 180 days.
Is the soil safe to grow vegetables in Moore County?
The federal record around Moore County is a meaningful one — 169 documented sites, mostly Underground Storage Tanks entries (102), the nearest Underground Storage Tanks record about 0.2 miles out — 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.
