Frost dates, planting zones, soil types, and what actually thrives in Mississippi — from mountains to coast.
Frost dates & zones
Mississippi spans USDA zones 7b (north) to 9a (Gulf Coast). Verify your exact zone and frost dates with your county Extension office — elevation and microclimates create real variation.

Delta soils are productive but may need potassium and micronutrients. Hill country clay needs compost and lime. Sandy South MS soils need nitrogen and organic matter. MSU Extension soil tests are available through county offices.
Know your soil
The Delta's dark, silty alluvial soils are among the most naturally productive in the world — flat, rich, and moisture-retentive. The hill country in Central and North Mississippi has red clay loam that needs organic matter. South Mississippi has sandy soils that drain fast.
