What this means

What Sebring soil means for gardens, lawns and septic systems

For gardens

Typical topsoil in Sebring soils is moderately acidic: pH 5.8 (most land between 5.8 and 5.9). Many vegetables grow well here, and some gardens benefit from a little lime. Test before adding any.

Loamy topsoil (loam, silt loam and similar) covers 95% of mapped Sebring acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is silt loam (95% of mapped Sebring acres).

95% of mapped Sebring acres is somewhat poorly to very poorly drained, so soil stays soggy for long spells after rain and in wet seasons. Raised beds, plants that tolerate wet feet, and not working the soil while wet all help.

For lawns and yards

On 95% of mapped acres, rain soaks in slowly (hydrologic groups C and D, including dual groups that are D until drained). Expect runoff and puddles after heavy rain: core-aerate compacted lawns and keep ground sloping away from foundations.

A seasonal high water table comes within 18 inches of the surface on 95% of mapped acres, often in spring. Basements, sump pumps and lawns in low spots feel it first.

For a septic system

For conventional septic absorption fields, NRCS rates 95% of the acres in mapped Sebring soils very limited, 0% somewhat limited and 0% not limited (5% not rated, such as urban land, pits or water).

Where the soil is very limited (slow permeability, a high water table, flooding, shallow bedrock or steep slopes), alternative systems such as mound or sand-filter designs are common and cost more.

Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.
