Through the Tree City USA program, the Foundation promotes the practice of Plant Health Care. Plant Health Care is a holistic approach to plant care that focuses on the health and growth of plants. The practice of Plant Health Care was developed by the International Society of Arboriculture Research Trust, Tree Care Industry Association, and the USDA Forest Service.
