Curriculum for Therapeutic Horticulture Option

As a Therapeutic Horticulture student, you will acquire the skills and knowledge needed to design healing and adapted gardens and to provide therapy programs that improve the quality of people’s lives. Our curriculum stresses effectively treating such clients as senior citizens struggling with physical or cognitive issues, individuals with developmental disabilities, and at-risk youth with the restorative powers of gardens, landscapes, and green spaces.

As a Horticultural Therapist, you'll help treat patients with significant health or emotional problems through the healing influence of nature. The impacts of therapeutic gardening have been studied and documented with various populations.  Memory can be improved through learning a gardening process, coordination can be strengthened by planting, and connections can be made between the earth and those with emotional and mental disabilities.  Horticultural therapy is practiced throughout the world in a wide diversity of settings and cultures, including mental health settings, physical rehabilitation, veterans’ services, vocation services, corrections, long-term care and hospice, special education programs, and youth and community services.

Graduates of the Therapeutic Horticultural option may become Registered Horticultural Therapists, Community Garden Coordinators, and Rehabilitation Program Coordinators.

Active Learning

All Horticulture students at Oregon State University complete a 360HR internship or research project of their selection.  As a Therapeutic Horticulture student, you will select an internship which allows you to work with the concepts you learn in your courses.  If you plan to apply for AHTA Registration, you are advised to nest your 360HR OSU internship inside of a 480HR AHTA-approved internship, where you will be supervised by a Registered Horticultural Therapist.
