Devine, Texas, sits in USDA hardiness zones 9a-10b — a zone band wide enough that plant choice, not possibility, is the interesting question.
These conditions suit pecan, tomato, okra, and bluebonnet — a starting list any specific site will trim or extend with its own soil, sun, and drainage.
Even in Devine, no two yards are alike.

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.

What an experienced grower watches for around here
In and around Devine, two things run higher than the national average — CAFO (3 sites) and Nitrate (34 sites). That's not a problem with your land — it's information about it.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Frequently Asked Questions
What hardiness zone is Devine, Texas?
Devine sits in USDA hardiness zones 9a-10b, 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 Devine?
Devine 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 Devine?
Devine's zones 9a-10b support 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 Devine, really?
Officially, Devine sits in USDA zones 9a-10b (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 Devine?
The federal record around Devine is a meaningful one — 105 documented sites — 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.
How do I protect my plants from frost in Devine?
As the season closes around Texas's first fall frost near Oct 15 - Dec 15 (NOAA 30-year climate normals (1991–2020)), a few moves buy time: cover tender plants with floating row cover or an old sheet on still, clear nights, water the soil the afternoon before a freeze so it holds warmth overnight, and harvest frost-tender crops like tomatoes, peppers, and basil before the first hard night. Hardy greens and root crops shrug off light frost and often sweeten after it, so leave them in.
