The drain field is an essential part of any septic system. It includes the soil above the tank, where lines distribute water from the tank to be absorbed and treated. Some homeowners leave their fields completely empty, but it is possible to plant over these fields, as long as you choose the right plants and do so carefully. Here’s a guide for homeowners. 

Why Should You Plant Over Septic Drain Fields?

Planting over a drain field can benefit both the septic system and the overall property. Plant roots absorb water from the soil, which can clear away space for more water from the tank to easily absorb into the ground. Plants that provide some ground cover, like grass, also limit soil erosion, which protects the water lines that run underneath. 

Additionally, many homeowners simply enjoy the look and functionality of grass or landscaped areas. If the drain field is in the front yard, adding plants may improve curb appeal. In the back, homeowners may benefit from adding a functional lawn that prevents dirt and mud from spreading across the property. 

What Types of Plants Are Best to Grow Over Drain Fields?

The best plants to grow over a drain field are those with shallow root systems. Many homeowners simply plant grass or shallow-rooted perennials or herbaceous plants. Some popular examples include hostas, dahlia, and primrose.

Avoid trees or woody bushes and shrubs, as these woody plants often have deep root systems and disrupt underground water lines and can even damage septic tanks. Additionally, avoid planting vegetables or herbs over septic drain fields, as there may be a small risk of bacterial contamination. 

How Can You Carefully Plant Over a Drain Field?

In addition to choosing plants with shallow roots, avoid placing anything heavy or directing too much traffic over your drain field. For example, simply plant flowers by hand instead of dragging wheelbarrows or heavy equipment over the ground. These items can compact the soil and damage water lines, making it difficult for water to absorb into the ground properly.
