Clasping Leaf Pondweed
Clasping-leaf pondweed leaves are wide and wavy. They have a broad base that wraps around the stem. The upper part of the stem is branched and leafy with leaves alternately arranged on the stem.
Pond Dye can be used to limit sunlight into the pond. With reduced sunlight, photosynthesis cannot occur so growth will be stunted.
There are a couple options to control Clasping Leaf Pondweed. If you are not sure what treatment is right for your pond? Click here to view our product selection guide or choose from some of our most popular chemicals:
- Use a season long herbicide such as Airmax WipeOut or Sonar A.S.. One treatment treats Clasping Leaf Pondweed and many other common pond weeds for the season.
- Use a broad spectrum contact herbicide, such as Ultra PondWeed Defense, will quickly kill Clasping Leaf Pondweed. Because it does not stay in the water body, multiple treatments may be needed throughout the season.
Chemical Application Best Practices
Anytime you use chemicals treat weeds and algae, please keep in mind the following:
- Treat your pond in sections. Treat only half the pond's surface at a time. During hot weather or when treating heavy growth, it is important to treat no more than 1/4 of your pond at a time and wait the full 14 days before re-applying. This helps lower the risk of fish loss during hot weather or when treating heavy growth.
- Once the weeds have browned & died, use a weed cutter & rake to remove as much dead material as possible. This prevents an accumulation of dead plant material and muck.
- Take a proactive approach to pond management. Use PondClear, MuckAway and Pond Dye to keep your pond looking great. For more information, see our article on the Airmax Ecosystem.
