Course Overview
Trees are often the most overlooked plants in our landscape – until something happens. Many pests and diseases of trees can result in future problems unless they are addressed when first observed.
In this course, horticulturist Steve Kristoph will teach you to identify the common and not-so-common pests and diseases of ornamental trees, conifers, and shade trees, and discuss options for prevention and treatment. You’ll also review basic tree biology and best management practices that will help to prevent potential problems.
