The first part of this book is general information and it is written for indoor bonsais. The pictures of the bonsais are of smaller trees, not the large bonsai trees that you see in many books. These are trees that the average person can have in their home. I think that indoor bonsais are smaller than outdoor bonsais. The author says much of the fascination of this hobby is derived from the experience of watching a plant grow. So the first section he describes in detail how to grow a bonsai from the very beginning.
An indoor bonsai does not mean that it lives indoors all year. All bonsais grow better if they are outside as long as your area will permit. An indoor bonsai is one that can live in the house during the winter without a dramatic set back. Outdoor bonsais on the other hand must spend the winter out doors. If you try to keep them in the house for the winter they will eventually die. Most bonsai books include many of the indoor bonsais, but they don't label them as indoor bonsais and they don't tell you how to keep them thriving in the house for the winter.
The second section is the "A-Z of Indoor Bonsai Species". There are 45 indoor bonsais in this book. Each bonsai has a brief description of the tree or shrub. Position, Soil, Watering, Feeding, Training, Acquiring a plant, and Pest are described for each bonsai. It ends with any particular features that make it suitable for training as a bonsai. There is a picture for each bonsai described. The name and age of the bonsai are under each picture.
There are not many books that are devoted to indoor bonsais. The section on each species gives you good information. There is more information in this book than you will often find in a larger book. It's a good book for indoor bonsais. This book is not only for beginners it is for anyone who wants to learn more about how to care for indoor bonsai.
