Duckweeds tend to grow in dense colonies in quiet water, undisturbed by wave action. Often more than one species of duckweed will be associated together in these colonies.
Duckweed Control For Lakes & Ponds
Physical Management of Duckweed
Since Duckweed is a floating plant it can be removed by raking or skimming the ponds surface. It has the ability to multiply rapidly and may take multiple cleanings throughout the year to keep it under control using a rake or skimmer.
Products To Physically Manage Duckweed
Our parachute skimmer measure 5 feet in width and comes with a 24 foot pull line. It is constructed of 2 horizontal bars, one which has a floating device, and a screening net.
When you throw the parachute skimmer into the lake or pond, the bottom bar drops and creates an opening to collect Duckweed into the net as you pull it back to shore or to your boat.
