Horticultural Therapist-Registered (HTR) Directory

Connect with Professionally Registered Horticultural Therapists

Professional horticultural therapists possess foundational expertise in plant science, human science, and horticultural therapy principles, alongside practical experience applying these methods.

The American Horticultural Therapy Association (AHTA) defines a horticultural therapist as a professional who:

• Holds a minimum of a bachelor’s degree in horticultural therapy, or a bachelor’s degree supplemented by coursework in plant science, human science, and horticultural therapy.
• Has completed a 480-hour supervised internship in horticultural therapy.
• Is professionally registered as a horticultural therapist (HTR – Horticultural Therapist-Registered) with the AHTA.
  

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.
