About the CHTA

The Canadian Horticultural Therapy Association's mission is to promote the use and awareness of horticulture as a therapeutic modality. The CHTA provides information, support, and resources to its members via a quarterly newsletter, this website, a membership directory, and an annual conference.

The CHTA provides a voluntary professional registration process for its members and a voluntary accreditation process for individuals and institutions offering education programs in therapeutic horticulture and horticultural therapy.

Incorporated in 1987, the Canadian Horticultural Therapy Association is a network of over 175 members across Canada and abroad. Members include registered horticultural therapists and professionals such as occupational therapists, physiotherapists, recreation therapists, social workers, nurses, psychologists, landscape architects, and horticulturists; and home gardeners who have a keen interest in the connection between people and plants.

Members of the CHTA work in a variety of settings: nursing homes, hospitals, and rehabilitation centres; vocational training centres, substance abuse programs, and correctional facilities; adult day care centres, therapeutic farming communities, school and community gardens.


One of the key advantages of being a member is the opportunity to connect with others who work in the same or related fields.

About Horticultural Therapy


Horticultural Therapy (HT) is a formal practice that uses plants, horticultural activities, and the garden landscape to promote well-being for its participants. HT is goal orientated with defined outcomes and assessment procedures. HT sessions are administered by professionally trained horticultural therapists.

Therapeutic Horticulture (TH) is the purposeful use of plants and plant-related activities to promote health and wellness for an individual or group. A TH program leader is trained to use horticulture to promote well-being but goals and outcomes for individual participants are not clinically documented.

Both HT and TH recognize the positive benefits of the interaction between people and plants and gardens. Research indicates that HT is proven to be beneficial in a variety of healthcare, residential, school and rehabilitative settings.
