Can You Incorporate Native Grasses in Reed Bed Systems?

Native Grasses in Reed Bed Systems

Benefits of Native Grasses

Native grasses can provide several benefits when integrated into reed bed systems. They help to stabilize the soil, reducing erosion and increasing the lifespan of the system. Native grasses also facilitate nutrient cycling by sequestering excess nutrients from the graywater. For example, native grasses like switchgrass can remove up to 100 pounds of phosphorus per acre per year from the water.

Planting and Maintenance

When incorporating native grasses into a reed bed system, it’s essential to choose species that are suitable for the local climate and soil type. Native grasses can be planted alongside reeds or in separate zones within the system, depending on the design. To maintain a healthy balance between the grasses and reeds, it’s crucial to monitor water levels and nutrient loading to prevent overgrowth. Aim to maintain a maximum of 50% native grass coverage to prevent shading and competition with the reeds.

System Design Considerations

When designing a reed bed system incorporating native grasses, consider the following factors. Native grasses require a slightly deeper water table than reeds, typically around 6-12 inches. The system should also have adequate space for grass growth, with a minimum of 6 inches of root zone depth. Finally, native grasses can increase the system’s surface area, allowing for more efficient treatment and potentially reducing the system’s footprint.
