Now I have a lot of perennials planted and am trying to get ground cover to take the place of the grass, so really can't start over with the first method, and if I double dig probably uproot things I'm meaning to grow, right? The whole area is surrounded by cement so I was a bit disappointed the grass roots stayed alive. Any solution you can think of? Or just continue to uproot what I can as often as I can?
