In 2011, the global gardening industry was worth an estimated $187 billion dollars. That means there are millions of gardens all over the globe, and each and every one is different from the next. In the United States, the average food garden size is about 600 square feet. That may seem small, but the typical gardener spends an estimated 5 hours each week tending and caring for their garden. Not only is it a great hobby, but it is also a hobby that provides beautiful, and many times delicious results!
