My Black Thumb

I am seriously considering ripping out my entire garden and starting new. I just cannot stand the disorganized mess that I have. The English Garden effect is not working and I have no idea where to start. I think I have the ugliest garden in town. It may be due to my "plunking" or due to the fact that when we moved here, I had no idea what I was dealing with. Two conical evergreens need to be moved, I want simplicity and romance, with little effort. My garden is South facing, endures extreme heat, and sun.
