Tree bracing is a means of providing structural support for a tree to prevent it from falling. The process commonly requires rigid rods or flexible cables. Tree bracing can be used as a preventative measure, to help restore a tree that’s no longer growing in the manner or direction the property owner wants it to grow, or for something called “mitigation.” Tree bracing can be very effective for each of those functions. Guying and propping are other types of structural support.
The Process
When there are concerns with how trees are growing, one can use cables or rods to provide structural support. When cables are used, they are installed about 2/3 of the distance between the crown of the tree and the defect. When metal rods are applied they are usually installed just above or below the defect. Used together the cable and metal rods form a very effective brace. Some people opt to only use cables to address structural support because they are stronger and offer greater leverage. However, when metal rods are used they are always accompanied by cables.
Prevention
Preventing an anticipated structural problem with a tree is one common reason people employ tree bracing. If the property owner or an arborist identifies a structural weakness in an otherwise healthy tree, they may decide to use bracing to reduce the likelihood of the tree failing. One example could be a bur oak that’s in good condition, but has large limbs with ‘V-crotches.’ The property owner may elect to brace the oak to protect it from falling.
Restoration
Another reason to use tree bracing is to prolong the life of a damaged tree considered to be valuable. For example, if a property owner has a large sugar maple tree that’s lost one of its leaders due to a storm, it is exposed and vulnerable. That property owner may decide to brace the sugar maple to prolong the life of that valuable tree indefinitely.
Mitigation
Mitigation is another common reason property owners use tree bracing. Mitigation refers to reducing the potential a tree has for becoming a hazard. As certain types of trees age, it often becomes necessary to use tree bracing techniques to improve the safety of passersby. A common example of tree bracing is when a picturesque hickory with multiple stems towers over a picnic shelter. To reduce the chances of part of the hickory breaking off and damaging the shelter or injuring someone, a tree brace would be employed.
