Most horticultural therapy programs in the United States serve clients who are either in long-term residential programs or who are living independently in the community. This report describes a horticultural therapy program in a short-term residential program for individuals with a history of substance abuse. Its development, structure and benefits are presented, along with recommendations in the hope that similar programs may be developed. Recently a patient, who had participated in the horticultural therapy program made a gift for his primary therapist that summed up the program. It went like this, "The philosopher that said a job well done never needs re-doing, never weeded a garden".
