Plant Health Care (PHC) 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.

By definition, plant health care is the proactive approach to maintaining tree, shrub and groundcover health through holistic cultural management and integrated treatments.  The secret to understanding plant health care is learning how it is implemented, why it is necessary and what health benefits are gained from its practice.

Plant health care specialists must have a thorough knowledge of what constitutes acceptable and ideal environmental conditions for hundreds of species and be able to prescribe treatments for diseases, insect infestations and other harmful conditions. The task of providing a quality program requires a great deal of training in plant care. Health specialists focus on plant vitality and call upon a broad range of techniques designed to protect and enhance plant health. In addition, the best plant health care specialists focus on the client who expects personalized attention, customized service, accurate information and beautiful plants in good health.

The goal of a good plant health care  program is to maintain tree and shrub health by providing the proper growing environment for the plant. Health and vigor are achieved with preventative care for stress management; frequent monitoring and early detection of problems; informed decision making; integrated treatments that provide long-term solutions; and quality communication with the proprietor of the landscape. Plant health care is a commitment to preserve vitality and protect the safety, health and appearance of a landscape.

Many of the trees and shrubs that we cherish in our landscape are subject to environmental issues or factors such as insects, mites and diseases that compromise their ability to thrive. Our landscape plants may not be native to this part of the world or may be exposed to imported insects and diseases. Most significantly, they are exposed to situations that create stress, like construction, grade change, soil compaction, mechanical injury, over- or under-watering, road salt, and air pollution. In order for plants to thrive and survive, these issues must be addressed.
