Japanese Knotweed versus Garlic Mustard
In a battle between Japanese Knotweed and Garlic Mustard, two very invasive species, who would win?
I found several areas in my local public park where Japanese Knotweed and Garlic Mustard were growing almost on top of one another. I know that Garlic Mustard roots can excrete biomolecules that prevent other plants from growing. Could Garlic Could Garlic Mustard compete with Japanese Knotweed?
