Phragmites typically prefers still or slow-moving water, and as such are of particular concern in lakes, wetlands, and ponds, including your personal backyard pond.
How do you control a strangling dog vine?
Removal of dog-strangling vine is quite difficult once established. Ideally, digging out the root of a first year established plant will prevent its spread. Care must be taken to remove the entire root since plants can re-sprout from any remaining rootstock.
