Cameron County, in Louisiana, sits in USDA hardiness zone 9b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
On paper, satsuma orange, okra, pecan, and muscadine grape all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Cameron County lies within the Gulf Coast — a regional growing area with its own character.

Growing Challenges in Louisiana
What an experienced grower plans around here — each one has a move.
Extreme humidity and rainfall promote rot and fungal diseases
Raised rows, morning base-watering, and generous spacing keep the wet at bay — extension's resistant-variety lists do the rest.
Poor drainage in delta and coastal areas
Where ground stays wet, grow up — mounded rows and raised beds keep roots breathing through the wettest months.
Hurricane damage risk from June through November
Wind-tough perennials, proper staking, and fall crops in movable containers take the sting out of storm season.

Safe to Grow Here?
What the federal record shows across Cameron County — and how to grow with it.
We checked the federal record across Cameron County — 302 documented sites across 6 of the 9 source types we track.
The most significant on record: 3 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Cameron County carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

What an experienced grower watches for around here
In and around Cameron County, Nitrate runs higher than the national average — 126 sites nearby. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.

Frequently Asked Questions
What hardiness zone is Cameron County, Louisiana?
Cameron County sits in USDA hardiness zone 9b, 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 Cameron County?
Cameron County follows Louisiana's statewide frost window: last spring frost around Feb 15 - Mar 15 and first fall frost around Nov 10 - Dec 10, 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 Cameron County?
Cameron County's zone 9b supports a wide range — strong performers include Satsuma Orange, Okra, Pecan, Muscadine Grape, and Live Oak. 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 Cameron County, really?
Officially, Cameron County sits in USDA zone 9b (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 Cameron County?
The federal record around Cameron County runs heavier than most — 302 documented sites — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
Just moved to Cameron County — what should I know before planting?
Start with three facts. Cameron County sits in USDA zone 9b, which sets what survives winter; the statewide frost window runs about Feb 15 - Mar 15 to Nov 10 - Dec 10 (NOAA 30-year climate normals); and 302 documented sites sit on the federal record here, so a soil test before food beds is the smart first step. From there, matching plants to your actual soil and sun is the fun part.
