Frost dates, planting zones, soil types, and what actually thrives in Texas — from mountains to coast.
Frost dates & zones
Texas spans USDA zones 6a (Texas Panhandle) to 9b (Rio Grande Valley / Gulf Coast). Verify your exact zone and frost dates with your county Extension office — elevation and microclimates create real variation.

Blackland Prairie clay needs organic matter and gypsum — never till when wet. Hill Country limestone soils need compost and acidifying fertilizer. Panhandle soils are alkaline — avoid lime. Texas A&M AgriLife Extension county offices offer soil testing for $10–$15.
Know your soil
Texas soils are extraordinarily varied. The Panhandle has productive but alkaline sandy loam. Central Texas Hill Country has thin, rocky calcareous soils over limestone. East Texas Piney Woods have acidic sandy soils. The Blackland Prairie belt has heavy black clay (expansive — cracks in drought, shrinks in rain). The Rio Grande Valley has alkaline clay loam.
