Our sister company Green Extraction Technologies, LLC performs a root collar excavation. This procedure is done to get rid of girdling roots. Root girdling occurs when a tree’s roots grow into the trunk of the tree. This chokes the tree and makes it difficult for the tree to be able to take up nutrients from the soil.
A tree with girdled roots will die if it is not treated
