Why do tree roots turn into girdling roots?

What is tree girdling and why is it bad?
It’s called girdling—when tree roots encircle a tree’s trunk. If you had to describe it, you might say it looks like roots are choking or strangling your tree. Turns out, that’s exactly the case. Girdling roots do suffocate trees by cutting off the flow of food and water.
How do you identify girdling roots?
Girdling roots can usually be exposed by digging into the top few inches of soil on the side of the tree lacking a root flare. Use of an air spade by a certified arborist can expose roots without injuring them. Common signs of girdling roots include the tree showing signs of dying off, starting at the top of the tree downward.
How do you fix girdling roots on a tree?
Water a newly planted tree consistently and inspect the root flare for defects periodically.

Should I cut girdling roots?
Very large girdling roots should not be completely removed since they may be supplying large amounts of water and nutrients to the canopy. They may be removed in stages over time to allow the tree to slowly compensate for the loss of water and nutrient flow. If dieback occurs, removing dead branches is recommended.
What causes a tree to girdle?
A tree is girdled when water and nutrients can no longer flow between the canopy and the roots by way of the xylem and phloem (found directly underneath the bark). You will be trying to bridge the gap caused by bark damage, reconnecting the xylem and phloem.

Why do girdling roots expand?
Whatever the reason, girdling roots encircle or cross-over the trunk/root flare of a plant rather than radiating outward (like a bicycle’s wheel spokes). Over time the trunk and girdling roots continue to expand in diameter with each new annual growth ring. Before too long, severe compression to the lower trunk areas create tremendous pressure upon the underlying vascular system (i.e. xylem and phloem). As this constriction builds up the lower trunk stem may begin to swell.
Why are girdling roots called the silent killer?
