Word-of-mouth may be a great way to learn about some products, but word-of-mouth gardening tips can be a very bad idea. The age-old practice of passing along gardening tips and tricks is no guarantee you will get a good result...it might even do the opposite.  In her new book, garden expert C. L. Fornari looks at 71 common garden practices and uncovers the truth behind the lore.  Do marigolds keep the bugs out of the veggie patch? Will rusty nails turn hydrangeas blue? With humor and affection, she goes back in time to sort out the good, the bad and the just plain silly...and tells us why. COFFEE FOR ROSES combines gardening history and expert advice into one useful, time- and money-saving package. The author’s award-winning full color photography is throughout.
