There is an area of approximately 6,000 square feet that is full of mugwort. We would like to restore some native vegetation, but as the area is adjacent to a pond, I don't want to use herbicides in controlling the mugwort.
We are at the eastern end of Long Island in New York. Although we do not have a detailed land use history, most of the area was farmed until the past 30 years or so. Soil in the area is a silty loam.
We plan to till and overseed with a warm season native grass mix, but expect mugwort to come back in. What are some things we can do to prevent that?
