Our home is on 2 acres of woodlands that is slowly being taken over by invasive species. There is a lot of japanese barberry, garlic mustard, stilt grass, russian olive and now some rose. We are having a bunch of trees removed in the front of our house where hemlocks and cedars will be removed and chipped. My question is whether the chips from these trees would be useful in the woodlands to keep these species from returning once pulled, sprayed or cut down. I am trying to reintroduce native species where the invasives are being removed. Will the chips hinder their ability to establish themselves? I feel as though I am fighting a losing battle and was hoping that the chips might help.
