Parrot Feather is a submerged plant that frequently trails along the ground or water surface of ponds, lakes and canals. It is native to South America and blooms from the spring to fall. It is easy to see why this plant is called Parrot Feather: its delicate, feathery, bright green leaves grow in profusion. Leaves are oblong, deeply cut and feathery looking. The leaf color is bright blue-green. Like most Watermilfoils, Parrot Feather leaves are arranged in whorls about the stem. Its leaves are in whorls of four to six. Stems can be five feet long. Stems trail along the ground or water surface, becoming erect and leafy at the ends.
Pond Dye can be used to limit sunlight into the pond. With reduced sunlight, photosynthesis cannot occur so growth will be stunted.
Selective herbicides, such as Aquathol®, should be used to treat Parrot Feather.
Chemical Application Best Practices
Anytime you use chemicals treat weeds or 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 & 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™
