When trees have a poor branching habit, split or cracked limb structures, areas of decay, or a poor root system, there is always a risk for structural failure. Some tree species produce a heavy crop of fruit or acorns which adds to the potential for structural failure. Improper pruning in the past can also lead to structural failure. When these weak areas fail, large limbs, trunks, or entire trees may come crashing down on anything underneath them.
In the case of weak limb structures, cables and bracing rods may be installed to offer necessary tree/branch support. Properly placed cables between limbs can help redistribute the load of weight, allowing the limbs or trunks to support each other. Bracing rods are often used to support splitting limbs by bolting them together. Installing cabling/bracing offers additional support but does NOT offer any guarantee they will not fail in the future. Remember that ALL trees can fail given the right circumstances, regardless of their size.
