Data Story
About Soil in Washington County, Florida
Milder Acidity in Washington County
The average pH of 5.09 is notably higher than the Florida state average of 4.88, though it still falls below the national 6.5 median. This moderate acidity level offers a slightly more flexible environment for various plant species.
High Sand Content Limits Workability
The soil composition is 83.3% sand, paired with 9.1% silt and 7.2% clay. This high sand content ensures excellent aeration but limits the soil's ability to provide a stable foundation for heavy structures.
Low Organic Matter Requires Amendment
Organic matter is low at 1.84%, trailing both the national average of 2.0% and the state average of 8.03%. With an available water capacity of only 0.085 in/in, this soil needs regular composting and irrigation to support healthy growth.
Fast Drainage for Sandy Terrains
Official drainage data is limited, but the 83.3% sand composition points to rapid water movement through the soil profile. Gardeners and builders should expect dry conditions that require supplemental water for farming success.
Drought-Tolerant Planting in Zone 9a
In Hardiness Zone 9a, drought-resistant natives and heat-loving vegetables like okra and sweet potatoes perform best. Boost your soil's potential with organic mulch and start your backyard garden project this season.

Soil & Planting Advisory: Washington County
Soil Verdict
Washington County is in USDA hardiness zone 9a, a warm climate zone. where winter lows can reach 20°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
Washington County closely matches the Florida average hardiness conditions.
