What is phragmites?
Phragmites, also known as “common reed”, is a non-native, extremely invasive plant that thrives in either fresh or brackish wetland areas. Large plumes develop in the fall, sometimes growing ten to twelve feet tall. Phragmites spreads rapidly through it’s rhizome system and can easily take over an entire wetland area in a matter of a few years. Because it grows so tall and dense, phragmites will choke out the beneficial wetland plants and therefore provides little value for wildlife.
What do you spray on phragmites to kill it?
A glyphosate herbicide called Rodeo or Aqua Neat that when mixed with a surfactant is approved for all wetland applications. Spraying is done at a critical time in the early fall when the other wetland plants have gone dormant but the phragmites has not. CWH technicians are state-certified to spray glyphosate herbicides in wetland environments.
Is it OK to cut down your phragmites stand?
Yes, you can cut down your phragmites, but only after it has been sprayed with Rodeo/Aqua Neat in the fall and has turned brown (usually 3-4 weeks after spraying). If you intend to have your phragmites sprayed, do not cut it during the summer. The canes need to have sufficient green leaf surface when treated in order for the spraying to be effective.
