Vertical gardens are a great choice for those of you who are space-conscious. But, unless you want to pony up for a Living Wall system or the like, they can be complicated and costly to build on your own. So, I was pleased to find a vertical garden made using an over-the-door shoe organizer on Instructables. Aside from the actual soil and seeds, the installation requires only a few household supplies (curtain rod, hooks, a piece of wood, and a trough) and takes only four steps to build. While I'm not sure about how long the fabric would last, it's still a pretty clever solution to a small-space dilemma.
