Many admit that they would love to have plants in their house but they fear they have a black thumb. "I can't even grown cacti," one friend confessed. As you can imagine, the #1 question that I get asked is "What plants won't I kill?"
Having filled up just about every horizontal surface with flora, I turned to the wall for inspiration. I had seen plenty of outdoor gardens but I wanted to get a sense as to whether it was possible to build a healthy vertical garden in my home.
