Dirt On Gardening Viewer TipCathy of Eden Valley, California built a secluded "secret garden" in her back yard that doubles as a dog run. An iron fence provides a safe and secure refuge for her dogs, and inside the fenced area she selected plants and materials that are dog-compatible and blend visually with the surroundings. She used rocky mountain granite, moss-covered boulders and the types of trees and plants that might be found along a dry creek bed--manzanita, butterfly iris and forest pansy. Both Cathy and her canine friends get enjoyment from this carefully planned garden space.
