We have a garden in our front yard that was there when we moved in. I don't like it, and haven't been keeping it up. I want to get rid of it and plant grass instead. However, when we tried to use a rototiller to break up the roots of the plants/bushes in the garden, we hit big roots from the tree in our yard. So we were unable to rototill the garden.
Our neighbor suggested using weedkiller to kill the roots of the plants, but I'd like to do something less toxic, if possible. Is there any other way to kill the roots of the plants so that we can plant grass?
Thank you so much!!!!!
