Garden Design: Assess and Sketch

Whether designing a secret garden or an extensive wildflower garden, it's critical to evaluate, document, and sketch out a setting's existing details—built features, water movement, sun exposure throughout growing months, soil types, etc. This online session will help students develop longhand documentation and, more importantly, mark the assessed information, resulting in a visual diagram that provides a clearer understanding of any variables to consider. The more informed you are as a designer, the better a designer you'll be! We strongly recommend students have a scaled base plan before moving forward with this stage. Class Level: Intermediate
