I found a few gardening templates. Some were free and some cost a small fee. These gardening templates were extremely helpful in giving me an idea of how to plan a garden that would produce season after season and feed my family well.
I read a very helpful article that I think you will enjoy. It has the kind of information a gardener needs in order to plant a productive garden. You will find information that will help you determine how much to plant to feed your family. The article is complete with a table containing guidelines showing you how much an average family consumes and how much you need to plant to satisfy your family's food consumption.
For information on planning a garden read:
