Tree support systems use specific hardware to provide supplemental support by limiting the movement of limbs. These tree support systems can aid in safety and extend the useful life of a tree. Tree support systems cannot eliminate risk or hazard. Tree assessment is critical to determining which if any tree support systems can be used. The most common tree defect requiring a support system is co-dominant stems with included bark. Split and decay crotches can also benefit from support systems, but risk assessment done by a qualified arborist is paramount.

Tree support systems require ongoing inspection of the tree and its defects. Tree pruning in combination with support systems is also recommended.
