A Practitioner's Guide to Stem Girdling Roots of Trees

The purpose of this publication is to present an objective perspective of SGRs. Most importantly, this publication reviews the symptomology, potential causes, treatments, and prevention of decline associated with SGRs. It is intended for field and diagnostic applications by arborists, landscape managers, growers, and urban forest health specialists. Research on SGRs is limited, but more practitioners are becoming aware of the problem, and new information on the formation and effects of SGRs has been recently collected. The lack of information might be partly due to the fact that roots are not always clearly visible because they are buried under soil or mulch. Another reason for the lack of research on this subject might be incorrect or incomplete diagnoses of tree problems. Few practitioners investigate below ground during tree disease/disorder diagnostic efforts.
