Supplemental Support for Trees That Merit Retention
Not every tree with a structural defect must be removed. In appropriate situations, bolting and bracing can provide supplemental support for a weak, cracked, or partially separated union while preserving a tree that retains sufficient structural integrity and landscape value.
Bolting and bracing typically involve installing specialized rods, bolts, or related hardware through adjoining stems or limbs. The system is intended to limit separation and reduce movement at a specific defect. It does not restore damaged wood or return the union to its original condition.
At Eric Putnam BCMA Inc., recommendations are based on the defect, remaining sound wood, tree architecture, canopy load, species characteristics, surrounding targets, and long-term management potential. We first determine whether the tree remains a reasonable candidate for retention and whether structural support is likely to provide a meaningful benefit.
Understanding Bolting and Bracing
When Bolting and Bracing May Be Appropriate
A structural support evaluation may be appropriate when:
- A major stem or branch union has developed a visible crack
- Codominant stems are beginning to separate
- Included bark has created a weak attachment
- A split union retains enough sound wood to justify preservation
- Excessive movement is occurring at a specific union
- A localized structural defect affects an otherwise viable tree
- Previous storm damage has weakened a trunk or major attachment
- A mature tree has significant sentimental, aesthetic, or landscape value
- An existing bolting or bracing system requires inspection
Bolting and Bracing Services We Provide
The scope of work depends on the defect, tree condition, preservation potential, canopy load, and surrounding targets. The work may include:
- Inspecting the weak, cracked, or separating union
- Evaluating the amount and location of remaining sound wood
- Assessing canopy weight, branch movement, and tree architecture
- Determining whether bolting or bracing is appropriate for the defect
- Identifying whether pruning, cabling, or another measure should be considered separately
- Designing and installing a support system for the approved defect
- Establishing expectations for continued inspection and maintenance
How We Approach Bolting and Bracing
Evaluate the Tree and Structural Defect
We inspect the tree’s architecture, union configuration, crack or split, included bark, decay, canopy load, species characteristics, and target area. We also evaluate whether the defect is localized or part of a broader structural problem.
Determine Retention Potential
Not every defective tree is a reasonable candidate for support. We consider the remaining sound wood, the extent of separation, tree vitality, surrounding targets, the likelihood of continued movement, and the consequences of possible failure.
Design and Install the Support System
When bolting or bracing is appropriate, the system is designed around the specific defect and expected loading. The written estimate identifies the tree, supported union, installation scope, associated work, and relevant limitations.
Establish Continued Monitoring
Bolting and bracing systems should be inspected periodically as the tree grows and conditions change. Reinspection may also be appropriate after major storms, additional cracking, unusual movement, or significant canopy changes.
Do You Already Know What Plant Health Care You Need?
Request a free estimate if you want bolting and bracing for one or more trees with previously identified structural defects. If you need to determine whether a crack, split, codominant stem, weak union, or excessive movement requires support, or whether the tree remains a reasonable candidate for retention, schedule a paid arborist consultation.
Bolting and Bracing Does Not Make a Tree Risk-Free
Bolting and bracing provide supplemental support. They do not restore damaged wood, eliminate decay, reverse an existing crack, or guarantee that the supported tree or union will not fail. The hardware changes how movement and loading are managed at the supported area. The tree will continue growing and responding around the installation, while the original structural defect remains part of the tree.
Installation requires controlled penetration through living and woody tissues. For that reason, bolting and bracing should only be recommended when the expected structural benefit justifies the installation wounds.
Support systems require continued inspection. Tree growth, corrosion, hardware movement, additional cracking, decay, storm loading, and changes to the canopy may affect how the system performs. Additional work or modification may be recommended as conditions change.
Removal may remain the more responsible recommendation when a tree has extensive decay, major separation, multiple critical defects, advanced decline, insufficient sound wood, or unacceptable residual risk.
Why Homeowners Choose Eric Putnam BCMA Inc. for Bolting and Bracing
Bolting and bracing should never be treated as a simple hardware installation. We evaluate the defect, tree condition, surrounding targets, and preservation potential before recommending structural support.
Condition-Based Recommendations
We determine whether the tree remains a reasonable candidate for retention and whether the defect is appropriate for bolting or bracing.
Defect-Specific System Planning
The support system is planned around the union, crack, canopy load, remaining sound wood, and expected movement. Hardware selection and placement are based on the individual tree rather than a standard installation applied to every defect.
Clear Long-Term Expectations
We explain what the system is intended to support, what structural limitations remain, why continued inspection matters, and when additional pruning, cabling, modification, or removal may need to be considered.

Common Questions About Bolting and Bracing
What is the difference between bolting, bracing, and cabling?
Bolting and bracing generally provide rigid support at or near a weak, cracked, or separating union. Cabling provides supplemental support higher within the canopy to limit movement between selected limbs or stems. Some trees may require one system, while others may require a combination of support methods.
Can a split tree always be saved with bolts?
No. Retention depends on the extent of the split, the amount of sound wood remaining, decay, canopy load, tree vitality, surrounding targets, and the consequences of possible failure. Some defects are too advanced for structural support.
Does installing support hardware injure the tree?
Installation requires controlled holes through tree tissues. These are intentional wounds and must be considered when determining whether support is appropriate. The anticipated structural benefit should justify the installation, and hardware placement should be carefully planned.
Does bolting and bracing eliminate the risk of failure?
No. Supplemental support may reduce movement or help stabilize a specific defect, but it does not make the tree risk-free. Other portions of the tree can still develop defects or fail, and the supported union may change over time.
How often should the support system be inspected?
The appropriate inspection schedule depends on the tree, defect, hardware, growth rate, and surrounding targets. Inspection should also be considered after major storms, visible cracking, unusual movement, or significant changes to the canopy.
