What type of vegetation is best suited around a septic system?

The best type of vegetation around a septic system is grass or shallow-rooted plants that do not obstruct the drain field. This is because shallow-rooted plants have a minimal impact on the septic system, allowing for proper drainage and oxygenation of the soil without penetrating deeply into the drain field.

Grass can effectively help in preventing soil erosion and can also absorb some nutrients that may be present in the effluent, contributing to the overall balance in the septic system's absorption area. Additionally, the growth of shallow-rooted plants supports a healthy environment for soil microorganisms that play a vital role in breaking down waste materials in the septic system.

Choosing this type of vegetation helps ensure the functionality and longevity of the septic system while avoiding complications associated with larger tree roots, which can invade drain fields and lead to costly repairs. It also maintains the aesthetics of the property without imposing significant strain on the septic installation.
