Common Types of Pond Weeds and Identification

The sunlight is blocked, resulting in a sharp weakening of underwater light, which seriously inhibits the photosynthesis of sinking plants and wither and die. It can harm underwater life and encourage stagnation.

Submerged Weeds – These grow beneath the surface, with roots in the pond bottom. Examples include coontail and pondweed. They grow very quickly and fill a pond, they may tangling in equipment and crowding out fish habitat.

Emergent Weeds – These plants, such as cattails and bulrushes, grow along the shoreline with most of their structure above water. They can gradually take over the pond's edges.
