From reviews of the first edition:

"This book is so convincing that if you know anyone who is hard-headed and opinionated about not using organic gardening or least-toxic pest-control methods, this is a good place to start them on a change of perspective."

—Common Sense Pest Control

"This [book] ...leaves no stone unturned on the subject of chemical-free gardening. Garrett offers persuasive arguments in favor of a holistic approach to gardening that considers composting, soil enrichment with natural ingredients, mulching, alternative pest control.... This volume serves well as an up-to-the-minute reference, one that gardeners of an organic persuasion will likely consult repeatedly."

—Publishers Weekly

"[This] is one of the most practical and comprehensive works on gardening the natural way we've seen, a manual of condensed logical wisdom providing a complete program for today's gardeners."

—Avant Gardener

"This is a 'must-read' for home gardeners. It should be mandatory reading for commercial growers.... Add the Dirt Doctor to your library, keep it handy so you can refer to it from time to time as you would to your Sunset, your Bailey, or to your California Garden as an essential and reliable source of information."

—California Garden
