What USDA hardiness zones are in Louisiana?
Louisiana spans USDA hardiness zones 8b-10b — which is to say winter's coldest night runs from about 15°F to 40°F depending where in Louisiana you are, averaged over 1991–2020 (USDA PHZM 2023).
Is it too late to plant in Louisiana?
For most of the year, no — what changes is which crops still fit the days remaining. Across Louisiana, cool-season planting typically opens about four weeks before the local last hard freeze — county medians put that freeze near Feb 11, with the middle half of counties between Jan 30 and Feb 17 (NOAA 1991–2020 climate normals). Tender transplants wait two to three weeks past it, and fall planting counts back from first freezes mostly between Nov 30 and Dec 8 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.
When does frost risk typically end in Louisiana?
Across Louisiana, the middle half of counties see their last hard freeze (28°F) between about Jan 30 and Feb 17, with a county median near Feb 11 (NOAA 1991–2020 climate normals). 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 Mar 4.
How long is the growing season in Louisiana?
Measured between 28°F hard freezes, growing seasons across Louisiana's counties mostly run about 285 to 313 days, with a county median near 298 (NOAA 1991–2020 climate normals). Tender crops get a somewhat shorter practical window, since lighter frosts reach a few weeks past the hard-freeze dates on both ends.
What vegetables grow well in Louisiana?
Louisiana's zones 8b-10b support 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 Louisiana, really?
Officially, Louisiana spans USDA zones 8b-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 1,086 plants against what's actually there.
Is the soil safe to grow vegetables in Louisiana?
The federal record across Louisiana runs heavier than most — 47,113 documented sites, mostly Brownfields entries (18,317) — 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 Louisiana — what should I know before planting?
Start with three facts. Louisiana spans USDA zones 8b-10b, which sets what survives winter; last hard freezes range from about Jan 30 to Feb 17 across its counties (NOAA 1991–2020 climate normals); and 47,113 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.
