Gardeners know better than most people, that everything man has came out of the earth. Therefore they respect earth. But if you have decided to make a garden, you must first remember that on the face of this earth there are many places with no soil and that a garden can be made only where there is soil. If you live in a city or a town, I am thinking of your back yard. which probably looks as if it were covered with soil. But the dirt may not be soil at all. It probably was soil once. And you can make it soil again”provided you know what soil is.
