Hi Rob,
As a gardener, some go-to reference books include "The Well-Tempered Garden" by Christopher Lloyd for its insightful wisdom, "The Vegetable Gardener's Bible" by Edward C. Smith for practical advice, and "Planting: A New Perspective" by Piet Oudolf and Noel Kingsbury for innovative ideas. "The Complete Manual of Organic Gardening" by Steve Solomon is fantastic for organic methods. For beginners, "Rodale's Basic Organic Gardening" offers a great start. Lastly, "The Flower Gardener's Bible" by Lewis and Nancy Hill imparts valuable flower-specific knowledge. These books provide a wealth of knowledge for gardeners of all levels. Happy gardening!
