Course description

Introduction to Therapeutic Horticulture is a foundational, self-paced online course for professionals and aspiring practitioners who want to understand the field of therapeutic horticulture and begin exploring how plant- and nature-based approaches may fit within their work.

Through engaging, easy-to-follow lessons taught by Emilee Weaver and Katie McGillivray, HTR, you’ll build a practical understanding of the principles, evidence, ethics, and professional values that support safe and inclusive practice. You’ll explore common populations and program settings, facilitation considerations, and introductory horticultural knowledge, including ways to adapt tools, activities, and techniques for different participant needs.

This course is also the prerequisite for the Therapeutic Horticulture Facilitation, Design and Practice course, making it a helpful first step for learners who want to continue developing their therapeutic horticulture practice.

This course is designed as a starting point. You do not need to be a horticulture expert, an experienced gardener, or already working in therapeutic horticulture to begin. You’ll be guided through the core concepts step by step, with practical examples that help you understand how this approach can fit within different professional roles and care settings.
