Using one or more of these approaches provides a means to get rid of the plant at the site youre clearing. Use the approach that will best deplete the plants energy reserves. Since this will vary among plants, no one way can be said to be the best. Persistence pays. It usually requires several attempts before success is achieved.
To assist in keeping the exotics from returning, several things can be done. Plant as densely as possible, so very little room is left for the exotics to take hold. Likewise, a cover crop of annuals can be sown, giving perennials a chance to get established. Mulch can also be effective in reducing the return of weeds. Minimizing soil disturbance at the site is another key to discouraging the return of weeds. Or using a ground cover of less aggressive native plants works at keeping weeds at bay while getting more sensitive native plants established.
David discussed 10 highly invasive species that are widespread in southern Michigan and suggested ways to best control each particular plant. A quick overview of these follows.
