Control Pond Sedges

Many people ask how to get rid of pond sedges. The following options can be considered for how to control pond sedges.


Manual/Mechanical Control:

If you are considering how to remove pond sedges, physically cutting this plant and digging up the roots can be a somewhat effective method of control. However, physical control can be difficult. Pond sedges can re-grow from any seeds or roots remaining in the area.


Herbicide Control:

There are multiple options for how to kill pond sedges that offer some control.

  1. Cattail and Water Lily Control (Imox + surfactant) (for ponds or lakes) – liquids that are mixed and diluted with water and sprayed over the plants.


Treatment Tips:

When treating pond sedges,

  • With Imox or other systemic herbicides, treatment is most effective when the plants are mature or close to full grown. This allows for more plant surface to spray enough mixture on.
    • Treat in late summer to early fall to get better kill of the root systems. At this time, plants are pulling energy into their roots to store for the winter.
