Vertical gardening is a great way to utilize limited ground space. When restricted by available ground, as long as there is a blank fence or wall, more gardening is possible. Vertical gardening is also great for gardeners with disabilities who cannot bend down to tend plants growing on the ground. With vertical gardens, they can sit or stand and easily tend plants within reach. Another bonus is that vertical gardens can be set up both outside and inside, with living walls becoming more popular.
