What Is Tree Cabling & Bracing?
Cabling and bracing are structural support systems installed in trees to reduce the risk of failure in weak or split branches, co-dominant stems, and other structural vulnerabilities. Rather than removing a valuable tree, cabling can extend its life by decades by preventing the failure that would otherwise make removal necessary.
When Is It Needed?
- Co-dominant stems — where two trunks of equal size grow from one point, creating a weak included-bark union
- Large horizontal limbs extending over structures, driveways, or play areas
- Trees that have partially split but still have significant living tissue
- Mature, high-value trees with structural defects not yet requiring removal
- Trees in high-wind or exposed locations where extra support is warranted
Types of Support Systems
- High-strength steel cables — Installed between major limbs or stems to limit movement during storms
- Rigid bracing rods — Threaded steel rods through co-dominant stems or cracked sections to prevent splitting
- Dynamic flexible cabling — Allows natural movement while limiting excessive sway; gentler on the tree
