Post Oaks Sensitive Root Systems
Post Oaks are very tough trees. If left undisturbed in their natural environment, they can live to be over 300 years old. However, when their root systems are compromised by nearby construction and over watering of turf lawns, the summer heat can be devastating.
When Damage Has Been Done to a Post Oak
When a Post Oak is completely brown, like the one on the right in the photo above, it is most likely beyond saving. The tree on the left requires immediate treatment to have any hope of survival. Tree Shepherds’ ISA Certified Arborists would recommend that the crown be reduced as much as possible. This would decrease the demand on the compromised root system.
Steps to Recovery
An experienced certified arborist is needed to complete such a reduction, without causing further damage or ruining the looks of the tree. Our arborists would reduce approximately 25% of the canopy in this process. (Please see our article on Lion’s Tailing for more information on the importance of correct pruning techniques.)
A crown reduction is the first step in the tree’s recovery. If the tree survives the summer, further treatments may be recommended to increase the tree’s chances. This may include a fertilization program as well as treatment for the Phytophthora, a fungus that commonly attacks stressed Post Oaks.
Removal vs. Treatment
Trees add many benefits and value to a property. A mature, well-cared for tree can add the equivalent value of an extra bedroom to a home’s value. Removals, while necessary at times, can be costly. It takes a long time to replace a mature tree.
