Join Janet McDonough, Senior Instructor of Biological Science Laboratory at Wellesley College, to gain a new appreciation for this backbone of our landscape. From its origins in the glacial era, explore the characteristics of soils in New England and how that character is represented by the plants in our landscape. How is soil made? What are the components of a good soil, and what easy methods can gardeners use to tell what amendments are needed? From geology to biology, Janet will give us all the dirt on soil. This Monday, January 23 presentation is offered by the Wellesley College Friends of Horticulture in collaboration with the Arnold Arboretum of Harvard University, the Boston Junior League Garden Club, and the New England Wild Flower Society.
