Gillman (horticultural science, U. of Minnesota) and Maynard, a master gardener, assess gardening recommendations related to soil, water, pests, diseases, weed control, mulch, annuals, perennials, bulbs, trees and shrubs, vegetables and fruit, and lawn care. They outline their thoughts, based on facts, about the usefulness and worthiness of some of the most common advice, explaining the reasoning and research behind it. Chapters are divided by the quality of advice--good, debatable, and wrong advice--and explain what happens, how to implement tips, and better solutions when applicable.
