To enhance the credibility and quality of horticultural therapy programs, it is essential that horticultural therapists document the effectiveness of their work (Zandstra, 1987). The systematic approach to horticultural therapy described here was designed to provide the therapist with a model to follow in the therapeutic process. This systems approach adapted from Systematic Counseling, Stewart, et. al. (1978) provides a process for assessing client needs, establishing goals and objectives to meet those needs, and for objectively evaluating the outcome of therapy. Although the systems approach has been designed for use with individuals, it can also be used with groups of clients by establishing goals, designing learning objectives, and creating horticultural objectives that are applicable to the whole group.
