Horticultural Therapy Certificate Program


The NYBG Horticultural Therapy Certificate Program helps students begin or complement
their careers through an in-depth exploration of skills and innovative methods using plants
and the growing environment to heal and rehabilitate people. Taught by practicing horticultural
therapists, this program trains students in the design, implementation, and operation of
programs for individuals and groups in a wide variety of health care settings and human
services programs.
Upon completion of the program, students will:
  • Understand the characteristics and etiologies of the various populations served by horticultural therapy.
  • Demonstrate skills in goal setting, activity planning, risk management, evaluation methods, plant selection, and accessible design.
  • Prepare proposals to deliver horticultural therapy programs in various venues including public settings, not-for-profit organizations, private companies, and independent contracting services.


Certificate students must complete 189 total course hours (181 required + 8 site visit hours), plus a 100-hour internship.
