What this means
What Benndale soil means for gardens, lawns and septic systems
For gardens
Typical topsoil in Benndale soils is very strongly acidic: pH 5.0. Most vegetables and lawn grasses do best around 6.0 to 7.0, so lime is often needed; blueberries, azaleas and rhododendrons like it as it is.
Loamy topsoil (loam, silt loam and similar) covers >99% of mapped Benndale acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is fine sandy loam (96% of mapped Benndale acres).
100% of mapped Benndale acres is moderately well to excessively drained, which suits most garden plants.
For lawns and yards
Most land is in hydrologic groups B and C, where rain soaks in at a moderate pace.
For a septic system
For conventional septic absorption fields, NRCS rates 17% of the acres in mapped Benndale soils very limited, 69% somewhat limited and 13% not limited.
Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.
