Horticulture therapy was first identified in the 1800s by Dr. Benjamin Rush as a way to provide psychological, developmental, and physical benefits through cognitive-based skills teaching. According to the American Horticulture Therapy Association, gardening provides advantages like reducing stress and improving memory, while also encouraging teamwork, nurturing behavior, and teaching marketable skills. Penrith Farms is a 320-acre community in Washington that uses organic gardening and life skills programs to build confidence for young adults transitioning from their teen years.
