Cabling and bracing trees are scientifically approved methods for supporting trees with split crotches, or for trees that have limbs or crotches that are predisposed to failure. Most (not all) cables we see installed by other companies in the area are installed incorrectly. Almost every time, besides using inferior hardware, the cables are installed either too low in the tree or too far down the limb they are supposed to support.
Safety factors such as proximity to power lines or other utility lines are paramount. Metal cables conduct electricity and must never be installed in trees where power lines contact the tree. Also, metal cables can rub against themselves or tree limbs, so they must always be installed free from obstructions.
At New Image Landscaping & Tree Service, Inc., we prefer to use through-bolts, which we have found to be much stronger and resistant to breaking in storms. They are especially needed in larger trees. When done properly, cabling and bracing will often save limbs or entire trees. They are generally considered permanent solutions, although constant re-inspection and monitoring/pruning is always recommended. We are happy to come evaluate your trees to see if they even need cabling or bracing. Contact us at (626) 421-6270, or complete a contact form if you want an honest professional evaluation.
