There are only seven sections because the book is intended to be a quick read. It is somewhat a reference book, though, because much is packed into it and it covers a great deal. The book is concise, but generally thorough in relaying key essentials for gardening and for planning out and establishing a landscape. Points are made that relate to these tasks. The warmer and hotter areas in the southern American states (and in Hawaii) are the more at-issue locations that tie in with the book, but the points can be applied to any lot, anywhere in the world and regardless of year-round temperatures.
