Horticultural therapists have a foundation of knowledge in plant science, human science, and horticultural therapy principles and experience in the application of horticultural therapy practices.

The American Horticultural Therapy Association supports the definition that a horticultural therapist is someone who:

• Has a minimum of a bachelor’s degree in horticultural therapy, or the minimum of a bachelor’s degree with additional coursework in plant science, human science, and horticultural therapy.
• Has completed a 480-hour internship in horticultural therapy.
• Is professionally registered as a horticultural therapist with the American Horticultural Therapy Association as an HTR, Horticultural Therapist-Registered.

Therapists must explicitly opt-in to this database. Therefore, this is not representative of the exact number of HTRs throughout the nation or in any geographic area.
