Only a glance around the tri county region will be enough to remind you that we grow some magnificent trees here in the Pacific Northwest! However, with urban intrusions on century-old wildland, sometimes our trees outgrow the ability of their natural structures to support them. That’s when the people of the Portland area call us for tree cabling and bracing.
At Portland Tree Service, we would prefer that trees and conifers grow in the correct habitat, with room to spread to their natural structure, both above ground and below. This isn’t always the case. While trees will tolerate some damage, sometimes there is a danger that its failure can cause damage to surrounding structures or landscape. In these cases, additional supporting is required.

What is Cabling and Bracing?
When branches and tree stems are deemed to be unsafe or unable to maintain their structure on their own, we install cables, rods and braces to hold things together. Imagine this as a tree-version arm cast or knee brace to help stabilize the formation.
Sometimes these are only required temporarily, during the tree’s own healing process. In other cases, these are permanent additions the tree will eventually surround with trunk and stems.
The OSU Extension Service notes numerous reasons why a tree might require this kind of care. Significant damage to root structure from soil disturbance or compaction means the underground portion of the tree can no longer safely control movements in the upper portion. Swaying in the wind is no longer a picturesque event but a nail-biter of worry.
Sometimes a poor pruning job means one side of a tree is heavier and fuller than the other, risking a topple. Obviously, this can be Mother Nature’s fault during a storm too. When additional appropriate trimming will not create a sturdy balance, bracing may be needed.
Even natural tree growth can produce risky situations. When two stems grow together like conjoined twins, they can form a v-shaped joint called a v-crotch, with what appears to be a crack down below. The danger is that one side of the tree may twist in a direction different from the other, and they crack apart or split down the trunk. Cabling above the v-crotch or rods through major stems offer additional support in these cases.
How Does This Help?
These supplemental structural supports keep the upper portion of the tree from twisting, swinging or swaying in a way that causes it to fail. Cables are made of high-strength steel and attached to threaded rods inserted in branches or stems. Sometimes it is possible to keep rods or cables within the tree itself, attaching weaker areas to strong sections. Each situation is unique; there is no one-size-fits-all solution.
Our International Society of Arboriculture (ISA) Certified Arborist inspects the structure and condition of the tree. We assess how cabling and bracing can protect the future safety of the tree, your property and the surrounding landscape. You will also learn how long the supporting structure might need to be in place, and if further care or treatment might be required.
