Static cabling systems are used to provide supplemental support to leaders, individual branches and/or entire trees. Steel systems are recommended for:
- Horizontal installations between stems with obvious bark inclusions.
- Species known for good compartmentalization of wounds.
- Stout, tapered trees known to have minimal movement in ice and wind.
- Situations requiring minimal movement.
- Vertical support of horizontal limbs.
A static cabling system is installed to restrict the distance that branches can have in relation to each other. Installed across a weak junction, they can reduce the risk of failure. Installed on an overextended branch, they can support the branch.
Pruning should also be considered in conjunction with steel support systems. For young trees, pruning is the preferred method to eliminate codominant stems. On larger, more mature trees, the combination of pruning and a support system can reduce the risk of failure. For trees with extensive decay or a damaged root system, removal is often the best remedy.
