Explore principles of garden design and develop a plan for a specific area of your yard during this five session class. In this beginner-level design class, you will explore the importance of line, scale, circulation, unity, and repetition as the organizational components of a coherent garden. You’ll also consider finer details such as color, focal point, depth, layering, and connecting indoors to outdoors. Christie Dustman, designer, APLD, will use before-and-after examples of projects she has completed to illustrate the design process. You will be required to draw a base plan for your site and identify your wish list of features. In analyzing your own and your classmates’ base plans and needs, you will practice the process of design and then begin to apply principles to your site plan. Christie will then lead in-class reviews, soliciting solutions from students and suggesting her own. You will leave class with a plan in progress from which to continue your design exploration. This class is primarily about garden space, and, as such, will not include garden design, though some key plant elements may be discussed.
