Can You Grow Plants Over A Drain Field?

drain field plantsMost homeowners are aware that trees and shrubs are a no-no for a drain field. The roots can penetrate into the pipes and cause serious issues. However, this doesn’t mean you are limited to a barren landscape devoid of greenery other than plain grass. We’ll list some acceptable drain field plants.

Drain Field Plants: Safe for the Septic?

Upon septic installation, some technicians will warn the homeowner not to plant anything other than grass. This is by no means an ironclad rule. Installers say this just to err on the side of caution.

The truth is that you can grow drain field plants, as long as they have shallow root systems. In fact, not only is this allowed, but we actually encourage it. The right kind of drain field plants actually help the drain field by sucking up excess moisture and preventing erosion.

A lot of septic damage occurs due to soil erosion by excess water. We frequently see poor soil conditions when performing septic repairs.

We would even go as far as say that the presence of weeds is beneficial in this sense. Even if you prefer no plants, then at least consider a tall grass species, such as fescue or Kentucky bluegrass.

Drain Field Plant Types to Consider

Below is a list of plants generally safe for a drain field. We say “generally” because variables, such as soil type, amount of sunlight, and time of year come into play.

  • Wild geranium
  • Brown-eyed Susan
  • Old field goldenrod
  • Smooth blue aster
  • Rough blazing star
  • Birdfoot violet
