I found this to be an excellent guide for the beginner. Although published in 1996 few of the basic things about growing citrus have changed since. The book is very well laid out with a good directory and index so things are easy to find. It starts with a detailed map of the citrus growing areas of the US where the citrus region of California is divided into four separate areas followed by Arizona, Texas, the Gulf Coast and Florida with average July highs, average days below 32F and record lows. Each of these areas is then discussed in more detail and divided into sub areas where local conditions are explained and some of the best-suited varieties are mentioned. There is a very interesting chapter about understanding micro climates such as cold air movement, exposure to wind from different directions and having buildings, pavement and large bodies of water nearby. I have not found information on these topics in such detail in other books.
There are concise chapters on the history of citrus, birth of modern citrus varieties, citrus and climate, growing citrus in containers and in cold climate areas. There are more detailed chapters about planting, caring, watering, mulching, fertilizing, pruning, protecting trees from cold and caring for cold-damaged citrus. There are many useful step-by-step drawings. The book is well-illustrated with good quality large-size photos.
This book is mainly about outdoor growing in the US citrus belt. If you are looking for information especially on container growing or growing citrus in colder climates there are more detailed instructions in other books. If you are looking for information about the suitability of the 100 most common citrus types to your specific US region, this book is for you. The descriptions are extensive with detailed entries on general, fruit and tree characteristics. Each variety has a box that indicates its suitability to each growing area and the expected harvest times. I found this to be very useful.
All in all there is a great deal of practical hands-on information and if you are thinking about choosing and planting your first citrus tree this book will not only get you started but will keep you thinking about adding new varieties. The only criticism I have is that there are no photos attached to each described variety but nowadays it is easy to find pictures on the Internet. The thing that has changed in the past 15 years is the disease and pest situation. There are drawings of the most common insect pests and instructions on using pesticides and general prevention of disease. Again, information on the more recent diseases can easily be found on the Internet.
