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. Feel free to use the information below to facilitate your pond weed identification goals, or contact us today to talk to our customer support team about the right control product for your pond or lake.

Water Lettuce

Water Lettuce

Water lettuce is an invasive plant commonly found in the southeast region of the United States. It grows in expansive mats that block sunlight to submerged aquatic plants, leading to lowered levels of bio-diversity.

Water Hyacinth

Water Hyacinth

Water Hyacinth can grow in height to 1 meter above water the surface and is supported by an erect stalk with a single spike of 8 to 15 flowers.

Watermeal

Watermeal

Watermeal is small in size and free floating. It is the world’s smallest flowering plant and resembles small grains of green cornmeal.

Pond Algae

Algae is commonly referred to as “pond scum” or “pond moss” and typically forms greenish mats upon the water’s surface.

Duckweed

Duckweed floats wherever the wind or currents take it, absorbing nutrients from the leaf undersurface and a very fine root hanging from it.
