Spatterdock is a perennial plant that has leaves roughly heart shaped. The leaves can be as large as 8-16 inches long by 10 inches wide. Flowers are yellow and are either at the surface or stand above it.
Other Names: Cow Lily
Spatterdock can be cut or the rhizomes can be dug up. It will be difficult to control this way because it will regrow from seeds and remaining rhizomes.
Broad spectrum contact herbicides, such as Ultra PondWeed Defense®, will quickly kill any part of the plant it touches but 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, if the weather is hot, only treat 1/4-1/3 of your pond. Wait 10-14 days between treatments.
- Once the weeds have browned, use a rake to remove as much dead material as possible. This prevents an accumulation of dead plant material and muck.
- Treat your pond with the proactive approach to pond management. Use PondClear™, MuckAway™ and Pond Dye to keep your pond looking great.
