Weed Control

How to Control Aquatic Weed Types and Aquatic Plants

Ponds grow a variety of pond weed types, many of which look similar. The aquatic weed identification information below lists the most common weed types -- including emergent, submerged, and floating weeds -- to help you explore and identify aquatic weeds in your pond or lake.

For those looking for weed control solutions, Lake Restoration has developed all-in-one pond and lake weed control kits that make it unnecessary to identify the type of weeds in your pond.
