Girdling or circling roots can cause serious issues for your tree if they're not addressed. A girdling root is one that circles part of a tree's trunk or root flare instead of growing outwards away from the tree. Over time, as the trunk and girdling root thicken, pressure builds up and the vascular tissues in the trunk that transport water, nutrients, and sugars can be cut off.
This can lead to crown dieback in some large branches, and can cause the tree to decline or die entirely in the worst cases. To address a girdling root, it's best to do it when the tree is young and vigorous. Make sure the root flare is always exposed, and check to see if you notice any roots that are circling the stem. If so, cut one or two each winter until the issue is resolved.
