Tree Cabling & Bracing
Providing a little extra support to strong trees
What is Tree Cabling?
Tree cabling is an arboricultural technique used to provide structural support to trees that may have weak or compromised limbs or branches.
This technique involves the installation of cables and/or braces within a tree's canopy to help reduce the risk of branch failure, improve stability, and prolong the tree's overall health and longevity.
Tree cabling is typically employed when a tree's structural integrity is compromised due to heavy foliage, weak attachment points, or storm damage.
Cables (also called flexible braces) are installed in the crown (top) part of the tree to limit the movement of weak joints or between co-dominant stems.
Braces, like Cables, are installed in the crown, but braces are rigid and installed through the trunk sections that need to be stabilized.
Guys are used to stabilize trees - usually when newly planted. These helpers need to eventually be removed or they can damage the tree as it grows around the wires.
This type of support is actually between the ground and the tree. These help to support a branch or tree from below. (These are seen often in the older Live Oaks.)
How Tree Cabling Works
Tree cabling serves as a preventative measure to mitigate the risk of branch failure, which could otherwise lead to property damage or injury. It's important to note that tree cabling should only be carried out by trained and certified professionals who understand each tree species' unique needs and can accurately assess the tree's structural integrity.
A certified arborist or tree care professional assesses the tree's structure to identify any weak or potentially hazardous branches. This assessment includes evaluating the tree's overall health, branch angles, attachment points, and potential points of stress.
Based on the assessment, the arborist determines where to install the cables and braces. Cables are typically installed higher up in the canopy, connecting two or more limbs together to share the load and reduce the risk of splitting
Different types of cables are used depending on the situation. Static cables are non-adjustable and are installed to provide direct support. Dynamic cables have a degree of flexibility and allow the tree to move naturally in the wind while still providing support.
