Cabling or bracing a tree helps to support the life of a tree. Trees that have more than one trunk (trees that form a “V” shape, see pictures below for examples) are prone to crack or split. By installing a cable it reinforces the weak spot in the tree to prevent it from cracking or splitting
Cables are installed to limit the limb movement at weak points in the tree to prevent it from cracking due to wind or accumulated snow.
Braces are steel rods installed to form a firm support in limbs and other parts of the tree. They are used to repair and reinforce split, weak or decaying areas of the tree.
