Session Description

Are your participants growing their connections? Reaching out as they build strong scaffolds of support? Gardening and nature-based activities infuse group programs with holistic therapeutic benefits while enhancing a sense of belonging and growing communities that thrive. We'll plant some seeds of creativity with structured activity ideas like "Watering Can Pass Off," "Making Potpourri," "Green Exercise," and "Lettuce be Different," drawn from the 300+ free activity plans in the Therapeutic Horticulture Activities Database (THAD), a resource created by horticultural therapists and housed on the University of Florida website.

Learning Outcomes

1. Advance knowledge of Therapeutic Horticulture (TH) & how TH activities can be adapted for Recreational Therapy programs. 2. Understand the different uses and activity adaptations of the Therapeutic Horticulture Activities Database (THAD) resources. 3. Utilize TH plans to inspire RT programs that build connections among participants and within communities while meeting other therapeutic goals.
