We’re not all lucky enough to have a big yard in which to grow a garden. Sometimes all you have to work with is a tiny apartment balcony or a teeny walled-in yard. If that sounds familiar, then a living wall garden could be just what you need. A living wall garden mounts vertically on a wall or deck railing so that you can exercise your green thumb in limited space. A wall garden can even help insulate your home if you hang enough panels on an exterior wall of your house, which will help you save energy!
