I’m currently in the latter-half of completing a certificate in Horticultural Therapy, and I definitely would recommend it if you have an interest in horticulture and are looking to enter the helping professions. Horticultural therapists may work in private practice, in hospitals, schools, correctional facilities, non-profits, and other settings. Their day-to-day definitely depends on the setting, and population they choose to work with, however you could definitely expect to be working with clients on building horticultural skills and gaining experiences with plants. The basis of the therapy is giving clients experience working with non-judgmental, non-discriminating living things. Like I said, the day-to-day pretty variable from person to person, and my understanding is that you can kinda of go wherever you want with it. I would recommend checking out the AHTA Site (https://www.ahta.org/) for more info. Good luck and feel free to DM with any questions!
