Lee County, in Texas, sits in USDA hardiness zone 9a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
A short list that earns its place here — pecan, tomato, okra, and bluebonnet — with any one site's soil, sun, and drainage making the final cut.

Growing Challenges in Texas
What an experienced grower plans around here — each one has a move.
Extreme heat (100F+ days) stresses many crops from June through September
Run the garden on spring and fall windows and give summer survivors afternoon shade — timing beats fighting the heat.
Rainfall varies dramatically — 8 inches in west TX to 56 inches in east TX
Your county's rainfall, not the state's, sets the watering plan — check your exact spot before designing beds.
Heavy black clay (Blackland Prairie) is difficult to work and drains poorly
A raised bed with amended soil turns Blackland clay from an obstacle into a backdrop — and that clay feeds deep roots well.
Flash drought conditions can develop rapidly even in wet years
Mulch deep and water deeply-but-rarely to grow drought-tough roots; a drip system pays for itself in the first dry summer.
For cultivar selection, pest pressure, and planting-time guidance specific to Texas, the Texas A&M AgriLife Extension Service is the authoritative local source.
Safe to Grow Here?
What the federal record shows across Lee County — and how to grow with it.
We checked the federal record across Lee County — 155 documented sites across 6 of the 9 source types we track.
The most significant on record: 10 Toxics Release Inventory facilities. Active industrial facilities reporting chemical releases to air, water, and land.
The federal record across Lee 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.

What an experienced grower watches for around here
In and around Lee County, two things run higher than the national average — Toxic Release Inventory (10 sites) and Underground Storage Tanks (98 sites). That's not a problem with your land — it's information about it.
Toxic 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.

Frequently Asked Questions
What hardiness zone is Lee County, Texas?
Lee County sits in USDA hardiness zone 9a, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.
When does frost risk typically end in Lee County?
Lee County follows Texas's statewide frost window: last spring frost around Feb 1 - Apr 15 and first fall frost around Oct 15 - Dec 15, per NOAA 30-year climate normals (1991–2020). Frost dates shift with elevation and local microclimate, so watch your own site's cold pockets.
What vegetables grow in Lee County?
Lee County's zone 9a supports a wide range — strong performers include Pecan, Tomato, Okra, Bluebonnet, and Jalapeno. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.
Which hardiness zone is Lee County, really?
Officially, Lee County sits in USDA zone 9a (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.
Is the soil safe to grow vegetables in Lee County?
The federal record around Lee County shows 155 documented sites — 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.
Just moved to Lee County — what should I know before planting?
Start with three facts. Lee County sits in USDA zone 9a, which sets what survives winter; the statewide frost window runs about Feb 1 - Apr 15 to Oct 15 - Dec 15 (NOAA 30-year climate normals); and 155 documented sites sit on the federal record — a typical footprint for a growing area, worth a look on the contamination map before food beds. From there, matching plants to your actual soil and sun is the fun part.
