Girdling Roots Tree Service in Clifton, NJ

Z Tree Experts received a call to go and inspect the health of a Purple Leaf Plum in Clifton, New Jersey. We always start our evaluations from the bottom of the tree and work up to the canopy to identify any problems. On this jobsite, we noticed the mulch was covering the root flare of the tree which can lead to many problems. We pulled back the mulch and noticed a girdling root, I informed the customer of the current and future problems this can have on a tree and suggested doing a root collar excavation and to trim off the girdling roots. 

What is a Girdling Root and How to Correct It

Girdling roots choke off the flow of water and nutrients within a tree. Food produced in the leaves is unable to properly travel through branches and girdling roots prevent the nutrients from reaching the roots. The same effect causes water to be unable to travel from the roots up the tree. They can compress and weaken the trunk of a tree at or above the root collar flare, which can cause it to lean and lose its stability. Trees with girdling roots can suffer a slow decline in health and a premature death.

The most common theory of the cause of stem girdling roots is that they develop as a result of trees being planted too deeply. When root systems are buried, less oxygen and water is available. Because of this, the roots will grow up towards the surface of the soil and tend to encircle the trunk.

Stem girdling roots can be removed by using wood gouges, saws or pruners if they have caused minimal stem compression. If one has caused extensive compression, removal treatment must be careful not to damage the stem. Such roots are frequently left in place when they cannot be removed safely. Always consult a professional to evaluate the situation and to see if corrective measures can be done.
