Tree Cabling, Bracing, and Staking: Using Structural Support Systems to Remedy Unstable Trees
When trees are not properly pruned or trained when young, they can grow in ways that threaten their health and the safety of the people, pets, and buildings around them. Mature trees with two or more trunks are particularly susceptible to this condition (referred to by arborists as having multiple leaders or co-dominant leaders or stems.) So, too, are open-canopied trees with limbs that grow horizontally or downward. Newly-planted trees can sometimes be weak-trunked or unstable, caused by close planting in the nursery, inadequate root balls, root damage, or planting in too-shallow holes or compacted soils.
Tree support systems — cabling, bracing, and staking — can be appropriate remedies for trees with structural deficiencies and instability. When installed and maintained correctly by qualified arborists, these support systems can:
