Abstract

\r\n Mark Arena, South Carolina, Berkeley County

\r\n

\r\n Observations of several trees leaning in a commercial parking lot lead to an investigation and survey. The investigation discovered that most of the trees that were leaning were root bound with no corrective action taken to remediate the problem. Also, it was noticed and surveyed that several parking lots in this region had similar problems. Leaning trees ranged from 6%-25% of the total tree population in the ten parking lots surveyed. Based on the fact that no corrective measures were taken it seemed apparent that information was needed to address this issue. The content of the article addresses root inspection prior to planting, description of girdling roots, root pruning and the potential liability of improper planting. Two websites were referenced for readers as additional resources to learn more about this subject.
