What this means

What Vermont soils mean for gardens, lawns and septic systems

For gardens

Typical topsoil in Vermont is strongly acidic: pH 5.1 (most land between 4.6 and 6.2). 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 82% of the land: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is fine sandy loam (44% of the land).

75% of the land is moderately well to excessively drained, which suits most garden plants.

For lawns and yards

On 76% of the land, 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 33% of the land, often in spring. Basements, sump pumps and lawns in low spots feel it first.

For septic systems

For conventional septic absorption fields, NRCS rates 94% of the land in Vermont very limited, 4% somewhat limited and 0% not limited (2% 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.

Data date
SSURGO as published on November 3, 2026 (most recent survey area update October 26, 2026). NRCS refreshes SSURGO each October.
Scope
Vermont: 5,902,549 acres of mapped land in 14 counties, pooled (not an average of county figures).
Method
Shares are by mapped land area: each map unit’s acres in the county times each soil component’s percentage. Open water is excluded. Topsoil values use the first mineral horizon of each component. Full methodology.
