Root Inspection & Air Excavation

Most trees fall over because of compromised roots due to factors such as decay, severance during construction, and constricted growing conditions. Root problems most often show up in shade and ornamental trees, although it can in other species. Currently the only root inspection procedure is invasive excavation by either digging or use of a hypersonic velocity "air gun" that blows away the upper soil. A Rayal Tree Care Company arborist is trained to identify, diagnose and treat root problems allowing some declining trees and shrubs to recover their health and beauty.

Root Girdling
Ever wonder why your tree has weakened or begun to die over a period of years? Root girdling may be causing this problem. Roots begin to grow around the main stem of the tree and cut off or restrict the movement of water, plant nutrients and stored food reserves. Within years, growth of the branches on the side of the plant affected by the girdling will be slowed. Left uncorrected, leaves will become smaller and lighter green, fewer leaves will be produced, and eventually the branch will begin to die back. The result can cause the tree to die within five to 20 years. Neither watering, fertilizing nor pruning will do little to correct the problem. Lindens, magnolias, pines, and maples other than the silver maple are susceptible to root girdling

Illustration # 1 shows a normal healthy root distribution spreading in all outward directions. Illustration # 2 (root girdling) shows roots coming upward and across. Illustration # 3 shows a trunk with a straight side or a concave depression on one side may also have a girdling root.

The development of girdling roots is created when the root system is restricted from growing out in a normal spreading manner. Any container-grown plant, where the roots are often forced to grow in a circular fashion, will exhibit this condition Root pruning is an absolute must for any container-grown tree or shrub at the time of transplanting. Multiple cuts are made through the root ball and similar cuts into the bottom as well to break apart these restricted roots.

Often tress surrounded by wooded or cement barriers will develop girdling roots. Possibly constant mulching, a desirable practice in many respects, may cause the formation of girdling roots.

Inspection
An arborist from Rayal Tree Care Company can perform an inspection when the tree is approximately six inches in diameter. Confirmation of this poor root structure can be made by exposing the roots. The soil is gently removed and carefully avoiding injury to any roots. If girdling roots are found, the girdling root will be eliminated. This procedure is usually done with a chisel or knife. The soil is then placed back around the tree base area. If the inspection reveals girdling and a considerable amount of damage, the most prudent move may be to replace the tree. Spending money on a weakened tree, which subsequently dies, can be an extremely frustrating experience; because correction of this problem is so labor intensive, the costs and benefits should be weighed carefully prior to making any decisions.
