Our guest is the noted gardening expert, Lee Reich, whose books include "Weedless Gardening" and "Landscaping with Fruit" -- and who writes a syndicated garden column for the Associated Press. He joins us to discuss his new book, "The Ever Curious Gardener: Using a Little Natural Science for a Much Better Garden." The book shows how one can employ scientific know-how to help plants thrive during a drought, outwit weeds by understanding their nature and composition, make the best year-round use of compost, and so forth. As was noted of this book by Jeffrey Gillman, the director of the UNC-Charlotte Botanical Gardens: "This is perhaps the most readable gardening book that I have ever encountered. Full of carefully presented garden practices supported by scientific know-how, it's fun and informative."
