Plant pathologist Deardorff and naturalist Wadsworth have created a book to diagnose and organically treat plant problems, whether related to cultivation, pests, or disease. The first section of the book is divided by plant part, from whole plant to leaves to flowers to fruits to stems to seeds. Gardeners use the symptoms present in their plant-or specific part of the plant-to answer a series of questions, arranged in flow charts and illustrated with color drawings, which lead them to a diagnosis of the problem. The entry then refers the gardener to the pages for solutions and, if available, a photograph of a plant with that problem.
