The most common reason a tree owner calls an arborist is concern that something is wrong with a tree. It may be that some of the leaves are discolored, a branch has died, or perhaps the entire tree has been dropping leaves. Sometimes the cause of concern is a minor problem that is easily explained and corrected. Other times the problem is more complex - with several underlying causes and a remedy that requires treatments extending over several years. Unfortunately, there are instances in which the problem has gone undetected for so long that the tree cannot be helped, and the only option is removal. If an arborist had been called earlier, perhaps the tree could have been saved.
The solution: PLANT HEALTH CARE Situations such as these led arborists to create Plant Health Care (PHC) programs. The objective of PHC is to maintain or improve the landscapes appearance, vitality and - in the case of trees - safety, using the most cost-effective and environmentally sensitive practices and treatments available. Plant Health Care involves monitoring, using preventative treatments, and adopting a strong commitment to working closely with you, the tree owner.
Why PHC, not TREE Health Care? While trees are dominant ornamental features in your home landscape, they share this stage with turf grasses, and shrubs, and bedding plants. And all these plants have one resource in common: the soil. The roots of trees, shrubs, turf grass, and bedding plants intermingle and compete for water and nutrients. In fact, the roots of a single mature tree may extend 60 feet or more out into your lawn or flower beds. Every treatment applied to the lawn (fertilizer and herbicide, for example) can impact the appearance and vitality of a tree. Conversely, treatments applied to a tree, such as pruning and fertilizing, can influence the appearance and vitality of the underlying turfgrass. The care of each plant in a landscape can affect the health of every plant in that landscape.
Why Contact an Arborist for PHC? Trees and shrubs represent a considerable long-term investment in your landscape. With proper care, these plants can provide beautiful surroundings, cooling shade and many other benefits for decades. Arborists have the experience and training to detect many potential tree and shrub problems before they become life threatening or hazardous. In addition, arborists can make tree and shrub recommendations, such as species selection and placement, to keep many problems from occurring in the first place. Arborists can also consult with other landscape services you may use, lawn care for example, to ensure that the treatments are coordinated and will not be harmful to your trees and shrubs. Remember, the potential size and longevity of trees and shrubs warrants their special attention in your landscape. Bedding plants can be replaced in a few short weeks, a lawn in a single growing-season, but it can take a lifetime or more to replace a mature tree.
What Does a Tree and Shrub PHC Program Cover? Every home landscape is unique, so there is no standard PHC program. Plant Health Care Programs do have features in common, however.
First, PHC involves monitoring tree and shrub health. This allows problems to be detected and managed before they become serious. The monitoring may be as simple as annual visits to check on a few special trees in your landscape, or it may involve more frequent quarterly or monthly inspections. The monitoring frequency and complexity of your PHC program depend on the size and diversity of your landscape as well as your particular landscape goals.
Second, if problems or potential problems are detected or anticipated during a monitoring visit, your arborist will develop solutions. The solution could be a simple change in your lawn irrigation schedule or more detailed suggestions, such as pruning or spot applications of pesticides.
Finally, PHC involves you, the client. Your arborist will give you information about your trees and shrubs. This ensures that decisions are made that address your concerns and are appropriate to your landscape budget and goals. Information may be provided through a variety of means. Obviously, discussions and answering questions are important means of conveying information, but many PHC programs include written recommendations after each monitoring visit. Plant Health Care is a program tailored to the needs of the client and his or her trees and shrubs.
How will My Trees & Shrubs Benefit from PHC? Because ornamental trees and shrubs can quickly succumb to problems, routine monitoring and timely treatments can protect your landscape investment and reduce expenses. A monitoring visit to your landscape might reveal:
- a hidden infestation of caterpillars that may defoliate the host tree
- a weakly attached branch that may fail and cause damage
- improperly pruned shrubs that may not be flowering as expected
Your PHC specialist can recommend treatments and changes in maintenance practices that can eliminate these problems while maximizing the safety and aesthetic quality of your landscape.
Individualized programs and flexibility are the heart of PHC. You will find that your arborist can design a Plant Health Care program that fits your budget and your goals.
