• Formed in 1973, the American Horticultural Therapy Association has helped horticultural therapy gain acceptance as a unique and dynamic human service program. AHTA is the only US organization concerned with the promotion and development of HT programming. More than 700 individuals and organizations located across the US, Canada, Japan, and beyond, are members.

Horticultural Therapy is a process in which plants and gardening activities are used to improve the body, mind and spirits of people. HT is an effective and beneficial treatment for people of all ages, backgrounds, and abilities.

It is used worldwide in hospitals, rehabilitation and vocational facilities, nursing homes and senior centers, community gardens, botanic gardens, schools, farms, horticultural businesses and prisons.
