Tree Health Guide
There are many reasons for a tree to look unhealthy—including drought, disease, invasive species, pests and improper planting. Diagnosing the problem can be difficult. This online Tree Health Guide provides basic information as well as immediate access to a network of professional arborists, foresters and Cooperative Extension Service agents who can help.
Our goal is to enhance your ability to care for your trees and shrubs by connecting you to the right people.
