Cabling and bracing are done for two reasons:
First: to stand a tree straight, support it, and keep it from falling over.
Second: to prevent multiple-stemmed trees from splitting.
When a large tree has developed with more than one trunk, there may not be adequate structural support to keep it from eventually splitting. By installing a high-strength steel cable into the canopy (upper area of the tree) when possible, we can prevent splitting without any ugly cables or visible guy wires down at the base
