Installing cables between major limbs reduces strain and helps support the tree. Cabling also helps reduce stress damage from high winds and excess ice or snow weight.
For large, weak, or split crotches, bracing is used to give direct support and reduce twisting strain on the tree. A metal rod is inserted through the crotch, and cables are placed above it.
Cabling and bracing does not repair a hazard tree, but when done correctly by a trained arborist, it can extend the time a tree or its parts are safe. Done incorrectly, it creates a more serious hazard. We do not recommend cabling or bracing as treatment for a hazard tree unless the tree has significant historic or landscape value.
