Hong Kong Association of Therapeutic Horticulture is allied with the American Horticultural Therapy Association; both parties become the affiliate member of each other.

HKATH is the first organization in Asia to have such honour. We believe that more cooperation between us will occur in the future. HKATH, with the recognition and support from AHTA, will continue to strike for our best in developing and promoting the profession of horticultural therapy in Hong Kong and Asia.
