The Sustainable Horticulture Certificate program consists of a series of core courses that includes Basic and Advanced Horticulture, Soils, Diagnosing Plant Problems and Botany for Gardeners. These classes teach best management practices necessary for gardening with minimal ecological impact. Electives further enhance students’ understanding of sustainable practices that help protect soil health, water resources, air quality and land usage, and result in the creation of aesthetically pleasing gardens.
