Data Story
About Soil in Live Oak County, Texas
Alkaline soils of South Texas
Live Oak County features an alkaline soil profile with an average pH of 7.60, higher than the national median of 6.5. While specific taxonomic orders are not mapped here, the high pH is characteristic of the region’s calcareous parent materials.
High clay for better retention
The soil is notable for its 30.7% clay content, which is significantly higher than many neighboring counties. Combined with 42.9% sand, this composition creates a dense soil that holds onto water and minerals tightly.
Rich in organic matter
With 2.06% organic matter, these soils are much richer than the Texas average of 1.66%. The available water capacity of 0.142 in/in also exceeds state norms, making this some of the more fertile ground in the region.
Careful with runoff
The soil belongs to hydrologic group D, meaning it has a very slow infiltration rate when wet. This can lead to rapid runoff during South Texas rainstorms, so gardeners should use mulch to prevent erosion.
Warm season crops in 9b
Hardiness zone 9b offers a nearly year-round growing season for peppers, tomatoes, and citrus. With organic matter levels this high, your soil is ready to support a highly productive backyard orchard!

Soil & Planting Advisory: Live Oak County
Soil Verdict
Live Oak County is in USDA hardiness zone 9b, a warm climate zone. where winter lows can reach 25°F. Warm winters keep soil biology active nearly year-round, accelerating decomposition but increasing pest and disease pressure in topsoil.
Planting Guidance
Tropical and subtropical plants are viable. Year-round gardening is possible, though summer heat may limit some cool-season crops. Frost is rare; tender plants can overwinter with minimal protection. Always match plant selections to the specific microclimate of your property — low spots, slopes, and wind exposure can shift effective hardiness by half a zone.
Soil Implications
Rapid organic matter turnover means soils can become nutrient-poor quickly; test annually and fertilize based on results. High soil temperatures favor certain soilborne pathogens; practice crop rotation and avoid overwatering.
Regional Context
Live Oak County is somewhat warmer than the Texas statewide average. The zone range of 9a-9b within the county means soil and planting decisions should account for local elevation and topography.
