Cabling, Bracing & Structural Support

Tree Support Systems in Delano

Some trees develop structural weaknesses that put them at risk of failure, but removal is not always the only option. Tree cabling and bracing are proven techniques that can extend the life of valuable trees by providing structural support to weak or damaged limbs and trunks. At ArborStone Delano Tree Service, our certified arborists are trained in advanced tree support systems that can save trees you want to keep while protecting your property from potential damage.

Cabling and bracing involve installing flexible steel cables and rigid support rods in strategic locations to redistribute stress and prevent failure. These systems are designed to work with the tree's natural movement while limiting dangerous flexing that could cause branches or trunks to split. When properly installed and maintained, support systems can add decades to a tree's life.

We follow standards set by the International Society of Arboriculture for all tree support installations. This ensures that our cabling and bracing systems are effective, safe, and do not harm the tree. If you have a tree with structural problems but want to avoid removal, give us a call for a free assessment.

When Do Trees Need Support Systems?

Not every tree needs cabling or bracing, but there are common situations where support systems can prevent tree failure and save valuable trees:

• Co-dominant stems: Trees with two or more main trunks growing from a weak junction are prone to splitting, especially during storms or heavy winds. Cabling can hold these trunks together.
• Weak branch unions: Branches attached to the trunk at narrow angles or with included bark are structurally weak and may break under stress. Support cables reduce the risk of failure.
• Split or cracked trunks: Trees that have started to split but are not in immediate danger of falling can sometimes be saved with bracing rods that hold the trunk together.
• Overextended limbs: Large horizontal branches that extend far from the trunk can become too heavy and break. Cabling provides supplemental support.
• Storm damage: Trees partially damaged by wind or ice may be stabilized with support systems rather than removed entirely.
• Historic or specimen trees: Mature trees with high value for historical, aesthetic, or environmental reasons are often worth saving even if they have structural issues.
• Trees with cavities or decay: Trees with hollow areas or decay can be strengthened with cabling to compensate for lost wood structure.

It is important to note that cabling and bracing are preventive measures, not guarantees. Support systems reduce risk but cannot completely eliminate the possibility of failure. In some cases, tree removal may be the safer option. We will always give you an honest assessment.

Types of Tree Support Systems

We install several types of support systems depending on the tree's needs:

Cable Support Systems

Cabling involves installing flexible steel cables high in the tree crown to limit movement of weak branches or co-dominant stems. Cables are anchored with specialized bolts through the branches or trunk. The cables are tensioned to restrict movement while still allowing natural flex. Cabling is the most common type of tree support and is used to prevent splitting of weak unions.

Bracing Systems

Bracing uses rigid threaded rods installed through the trunk or branches to physically hold together wood that has split or is at risk of splitting. Braces are installed perpendicular to the split and secured with washers and nuts. Bracing is typically used in combination with cabling when a tree has already started to split but can still be saved.

Dynamic Support Systems

Newer dynamic cabling systems use synthetic rope or webbing instead of steel cable. These systems allow more natural movement while still providing support, which can promote stronger wood development over time. Dynamic systems are often used for younger trees or in situations where traditional cables might restrict too much movement.

Propping and Guying

For low branches or leaning trees, we can install props (vertical supports) or guy wires (anchored cables from the tree to the ground). These systems provide direct support to prevent leaning or sagging. Combined with proper pruning, propping and guying can correct or prevent lean.

Installation and Maintenance

Installing tree support systems requires specialized knowledge and equipment. Our process includes:

• Thorough assessment: We evaluate the tree's structure, health, and risk factors to determine if support systems are appropriate and where they should be installed.
• Custom design: Each support system is designed specifically for the tree based on its size, species, structure, and the type of weakness being addressed.
• Professional installation: Our arborists climb the tree and install cables, braces, or other hardware using proper techniques that do not damage the tree.
• Regular inspections: Support systems should be inspected annually to check for wear, proper tension, and tree growth that might affect the system. We offer inspection services to ensure your support systems remain effective.
• Adjustments as needed: As trees grow, support systems may need to be adjusted, repositioned, or supplemented with additional hardware.

Tree support systems are not install-and-forget solutions. They require ongoing monitoring to remain effective. We recommend annual inspections to ensure your system continues to protect your tree and your property.
