*Aquatic Biologists recommends implementing preventative management techniques and physical removal prior to, or in conjunction with treatment.

Bushy pondweed has become more common in recent years; it can grow abundantly in some areas and cause problems. In most areas, it will not be a nuisance and is best left alone--removal may allow less-desirable plants to move in. When control is necessary, aquatic herbicides can be effective.

Plant Description

Leaves are narrow with tiny spines along the edges. Slightly enlarged at the base. Stems slender with frequent branching. Leaves oppositely attached, or in groups of two or more at a node. Leaves are densely concentrated at the tips.

Hints to Identify

Leaves are tapered to a fine point with tiny "spines"; seeds are shiny and smooth. Bushy pondweed is sometimes confused with chara, but chara has a musky odor when crushed and bushy pondweed does not.
