The use of tree and trunk injections by tree service companies has increased rapidly in recent years. A variety of compounds including nutrients, insecticides, and fungicides can be effectively applied via the tree’s vascular system. Achieving rapid uptake and distribution of injected chemicals within trees, however, can sometimes be difficult. Dr. Bert Cregg (Michigan State University, Departments of Horticulture and Forestry) will discuss how soil, tree, and weather interact to control sap flow and will provide tips to ensure optimal uptake during injection applications.
