3rd Class in the Therapeutic Horticulture Series

August 12 – September 23, 2024
August 11 – September 28, 2025

NC State University Department of Horticultural Science and the North Carolina Botanical Garden at UNC Chapel Hill have partnered to create an exciting online learning program. Therapeutic Horticulture: Accommodating Diverse Populations is the third in a series of online courses that teach the theory, practice, and profession of Therapeutic Horticulture. 

This six-week course is intended for a wide audience, including allied health
professionals who may want to incorporate plant-based activities into their existing
practices, master gardeners or volunteers, educators and other interested people who work with community members with diverse needs and abilities.
Students will learn to safely and ethically apply therapeutic horticulture
interventions with diverse populations of varying physical, cognitive, social, emotional, and cultural backgrounds and abilities.

The elements of Universal Design will be discussed in relation to the conceptualization and design of healing/therapeutic gardens that are used in TH programming. Students will become acquainted with various adaptive tools and techniques that enable participants of all abilities to connect with plants and nature-based activities in the least restrictive, strengths-based environment.

Using dynamic interactive forums with real-world examples, students will research, discuss, and reflect on best practices for accommodating diverse populations in therapeutic horticulture. References and resources will be provided for further study.
