Gardening explained. Not only did this book teach how to care for plants, it explained why a factor is beneficial or harmful to the plant's health. I learn best not by memorizing a bunch of dos and don'ts, but by understanding the logic behind how to make choices. This book did an excellent job of explaining that logic, covering both basic principles and practical specifics. The container aspect eliminated a lot of the ground soil analysis and garden bed preparation, which allowed me as a beginner to focus on learning everything else. I feel more confident buying and growing houseplants, vegetable gardens and herbs, and planting pretty flowers outside. I am so excited to start my three chosen planting projects from the suggestions and the end of the text. My only complaint is that the color photos promised throughout the text of the book were missing in the Kindle version.
