The most common reason for planting over a drain field is the prevention of soil erosion. Raised drain fields are commonly referred to as sand mounds can create an eyesore affect ruining the curb appeal of your home. Homeowners will often elect to plant in these areas in an attempt to beautify the sand mound.

There are several things to consider when choosing the best vegetation for your septic tank and drain field. Grass is by far the safest and most common type of coverage planted over the septic tanks and drain fields.

Select plants that are shallow rooted and adaptable to normal seasonal rainfall. Plants with a deep root system or more commonly referred to as “Woody Plants” will often make their way into the drain field, clogging lateral lines causing backups and damage to the system.
