That botany is not horticulture Mr. Rickett makes very plain in the first paragraph. His book is not concerned with ""How to grow plants,"" but, rather, ""How plants grow,"" and with this approach the budding horticulturist is enlightened about the rationale behind supplying sunlight, air, water and fertilizer to his plants. The better gardener is one who is firmly grounded in botanical principles. Understanding these principles is encouraged by the uncompromising terminology coupled with a simplicity of approach. For the gardener who really loves his craft and wishes to know the science behind it, this book is a find.
