Root collar excavation is the process of removing the dirt from around the trunk of a tree to inspect the base. This is done to investigate the extent of decay that is present or to view the structure of the roots to see if there may be a girdling root issue. Girdling roots are tree roots that gave been misdirected and grow around or across the tree trunk causing tree health issues.
Often, if homeowners are seeing issues with the leaves or branches of the tree, it is a sign to inspect the roots. If the tree was planted too deep, the roots cannot get the oxygen they need and therefore grow around the trunk of the tree, ultimately suffocating it. This is what is referred to as girdling roots. Although the tree will still grow, it will not be as strong. Root Crown Excavation is used to thoroughly examine roots and determine the best plan of action to get your tree healthy and thriving once again!
