Welcome to the American Horticultural Therapy Association 

Established in 1973, the American Horticultural Therapy Association (AHTA) is the only national US organization advocating for the development of the horticultural therapy profession and the practice of horticulture as therapy for human well-being. AHTA supports the professional development, education, and expertise of horticultural therapy practitioners. Individuals and organizations located across the US and beyond are members. We are a 501(c)(3) nonprofit membership-driven organization with the mission to promote and advance the profession of horticultural therapy as a therapeutic and rehabilitative modality.
