Data Story
About Soil in Bandera County, Texas
Rich Mollisols of the Hill Country
Bandera County is defined by Mollisols, a taxonomic order known for its dark, fertile surface layers. The average pH of 7.53 is more alkaline than the state average of 7.09 and the national median of 6.5. These soils provide a stable, nutrient-rich base for local ecosystems.
The Balance of Silty Clay
The soil contains 37.9% clay and 37.6% silt, creating a heavy silty clay texture that holds onto nutrients. Only 20.4% of the soil is sand, which means the ground can be difficult to work when wet. This composition is excellent for retaining moisture during the dry Texas summers.
Top-Tier Organic Matter Content
Bandera boasts a high organic matter content of 3.37%, more than doubling the state average of 1.66%. The available water capacity is also strong at 0.142 in/in, outperforming the state baseline of 0.133. This combination creates a naturally fertile environment for both wild and cultivated plants.
Managing Runoff in Group C
Despite being well drained, the soil belongs to hydrologic group C, indicating a moderately high runoff potential. Water penetrates the surface effectively, but heavy rains can cause surface flow issues on sloped terrain. Builders must account for the clay content when designing foundations to manage shifting.
Bountiful Options for Zone 8b
The mild winters of zone 8b allow for a long growing season of fruit trees and perennials. High organic matter makes this an ideal spot for backyard vegetable patches or orchards. Embrace the Hill Country climate by planting peaches or native wildflowers in this productive soil.

Hydrologic Group
Group C — Moderate-High Runoff
Soils with slow infiltration rates, often with a layer that impedes downward water movement. Higher clay content restricts drainage.
Drainage Class
Well drained
Water is removed from the soil readily but not rapidly. Optimal for most plants and construction.

Browse Soil AmendmentsFrequently Asked Questions
What type of soil does Bandera County have?
Bandera County's soil is classified as Silty clay. This indicates the relative proportions of sand, silt, and clay — 20% sand, 38% silt, and 38% clay. Clay soils retain water and nutrients but can have drainage challenges.
Is Bandera County's soil acidic or alkaline?
Bandera County's soil has a pH of 7.5, which is mildly to moderately alkaline. Sulfur amendments can lower pH if needed.
What is the drainage class for Bandera County?
Bandera County has a dominant drainage class of "Well drained." Well-drained soils allow excess water to move through quickly, reducing waterlogging risk and supporting most field and garden crops.
What crops or plants grow well in Bandera County's soil?
Based on Bandera County's Silty clay texture, pH of 7.5, and Well drained, the soil is well suited for drought-tolerant crops and native grasses, row crops and vegetable gardens, most annual and perennial crops.
What USDA soil order is found in Bandera County?
Bandera County's dominant soil order is Mollisols. Mollisols are fertile, dark-colored soils that formed under grassland vegetation. They are among the most productive agricultural soils in the world.
Soil & Planting Advisory: Bandera County
Soil Verdict
Bandera County is in USDA hardiness zone 8b, a warm climate zone. where winter lows can reach 15°F. Mild winters mean soil rarely freezes deeply, allowing year-round microbial activity and faster organic matter breakdown.
Planting Guidance
Warm-season crops, citrus relatives, and heat-loving ornamentals do well. Cool-season vegetables should be planted in fall and winter. 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
Warm soils accelerate organic matter breakdown, so compost and mulch need replenishing more frequently than in cooler zones. Sandy soils common in warm zones drain quickly; water-retentive amendments like compost or peat help hold moisture.
Regional Context
Bandera County closely matches the Texas average hardiness conditions. The zone range of 8a-8b within the county means soil and planting decisions should account for local elevation and topography.
