Frost dates, planting zones, soil types, and what actually thrives in Louisiana — from mountains to coast.
Frost dates & zones
Louisiana spans USDA zones 8a (north) to 9b (New Orleans / Gulf Coast). Verify your exact zone and frost dates with your county Extension office — elevation and microclimates create real variation.

South LA soils need drainage improvement more than fertility — raised beds help. North LA red clay needs compost and lime. The LSU AgCenter's soil testing lab is the go-to source; tests run $10 per sample.
Know your soil
South Louisiana's alluvial river soils are deep, rich, and moisture-retentive — built by centuries of Mississippi River deposits. North Louisiana has red clay that needs organic matter. The Florida Parishes east of the Mississippi have sandy, acidic soils. Drainage is the universal challenge in the south.
