Just finished reading Canadian author Liz Primeau's 'Front Yard Gardens, Growing More Than Grass'...and am now further compelled to turning over much of the front lawn into beds. I want to roughly border them in large boulders/rocks and perhaps create a berm effect, or not...thinking ahead to spring 2012 as we gardeners tend to do. Has any member done a similar project to my theoretical one? Methinks it's going to be expensive especially with the rocks...
