Yes I know google exists.. now that we've got that out of the way... I recently purchased a home, my first. And there is this terrible collection of three bushes/plant thingies that I've let die. I know I can use a water hose to create the border.m but what next? Can I just buy anysoil? What do I need? What is easy to keep but looks nice? What happens to the flowers in the winter? I'm in OKC by the way!
