American Pondweed

American Pondweed is an aquatic plant that has floating leaves as well as few submerged leaves.  These leaves are elliptical or oval in shape and are 4-7” long and 1-2” wide.  This is a perennial plant that has fruits that above the water and are a dark red or brown color.  American Pondweed can form dense mats which can block sunlight from entering the pond.

This plant can be removed by raking but it will reestablish from remaining roots and seeds.  American Pondweed can be treated using chelated or compound copper formulas, Reward and Cide Kick II, or dipotassium salts of endothall.
