Often times we get asked "what is duckweed?"Duckweed has the ability to multiply rapidly and can infest a pond or quiet bay in a matter of days. Duckweed can be a major nuisance for homeowners due to its ability to turn an otherwise beautiful pond into an unsightly mess. Luckily, controlling duckweed in ponds is very simple. We recommend PONDRestore® Ultra - it is easy to use and will eliminate duckweed from your pond.
How did it get in my pond?
Duckweed is commonly spread by migratory birds flying between ponds with the tiny plants clinging to their feathers. Duckweed is very prolific, and given enough nitrogen and phosphorus nutrients, it is possible for a new duckweed plant to be produced every 24 hours. This means that in just two weeks, a single parent plant can result in up to 17,500 plants!
Extensive mats of duckweed colonies may cover an entire pond surface, depleting oxygen and blocking sunlight. Fish and submerged plants can be killed. Because of this, duckweed infestation often contributes to poor pond health.
Duckweed can tolerate a wide range pH, between 4.5 and 7.5, as well as temperatures between 68F (20C) and 86F (30C), making duckweed a challenging aquatic plant management issue worldwide.
Duckweed is one of the smallest flowering, free-floating plants found around the world. Measuring just 1/16" to 1/4" in length, duckweed floats on the water surface in colonies not attached to the bottom. Duckweed floats wherever the wind or currents take it, absorbing nutrients from the leaf undersurface and a very fine root hanging from it.
Duckweed can have one leaf or up to three leaves, known as fronds, about the size of a pencil eraser head, with a single root hair.
Duckweed prefers eutrophic, motionless fresh water in wetlands, ponds, lakes and slow moving streams. Duckweed requires a lot of nutrients to grow - especially nitrogen and phosphorus. Major sources of nutrients include Canada geese, lawn fertilizer, agricultural run off, leaking septic systems, and tree leaves.
High levels of nitrogen and phosphorus indicate poor pond health, requiring nutrient removal in conjunction with treatments. Preventative measures should be undertaken to address nutrient levels in order to get rid of duckweed. PONDRestore® Ultra contains our best products to control duckweed and algae, including effective herbicide and nutrient reducing treatments.
