Horticultural Therapy
What is Horticultural Therapy?
Horticultural Therapy (HT) is an add-on therapy that uses gardening and nature-related activities to facilitate health and well-being. It is used with clients of all ages and by professionals in hospitals, long-term care facilities, schools, prisons, group residences, and day programs.



The Gardens’ Horticultural Therapy program was initiated by a Gardens’ docent in 1983 and is tailored to the strengths and needs of each group. Our on-site programs provide hands-on activities including plant propagation, harvesting and cooking fresh produce, garden maintenance, floral arranging, wreath-making, flower pressing, and much more! Visit the raised garden beds area near the Gardens’ compost area where you can see first-hand our on-site program at work.
Horticultural Therapy Program Services
Activities are centered around achieving specific therapeutic goals, such as increasing self-confidence, socialization, creative self-expression, improving communication skills, decreasing stress, or practicing skills related to activities of daily living. In our pre-vocational programs, participants have the opportunity to develop transferable job-related skills and responsibilities including gardening maintenance, tool inventory, and greenhouse management.

Program Models
We offer horticultural therapy programs for groups of 5-10 participants and charge a baseline of $15 per person per hour. Depending on the intensity of the program offered, this cost may increase.

The History of Horticultural Therapy at the Gardens
The Horticultural Therapy program was initiated by a docent, Helen Cowles, in 1983. It was then led by the late Dr. Juliet Niehaus (pictured left) for over 20 years. She built a program serving people with disabilities and other life challenges that received national recognition. She also cared diligently for our flock of chickens, another element of the program!
During these past few decades, the Tucson Botanic Gardens has served a wide range of participants, including senior citizen centers, memory care centers, local high schools, and recovery groups.
