Cabling & Bracing in Fort Wayne, IN

Cabling and bracing add support to a tree that has a structural weak point but is otherwise worth keeping. A cable is installed high in the crown between two stems or limbs to limit how far they can spread apart in wind; a brace rod is bolted through a split or weak fork lower down to keep it from opening. In Fort Wayne the classic candidate is a big silver maple with two or three trunks joined at a tight V, the kind of tree that splits in a summer storm or under ice.

Why tight forks fail

When two stems grow up side by side, bark can get trapped between them as they thicken. That included bark keeps wood from joining across the union, so the fork is weaker than it looks. Every windstorm works the stems back and forth. Silver maples, which the city's forestry plan names as the main tree in Fort Wayne's canopy, are prone to this, and so are Callery pears and some elms and lindens.

Industry standard work

The ANSI A300 standards include a section on supplemental support systems. Cables are usually set about two-thirds of the way from the fork to the tops of the stems, anchored with through-bolts or eye lags into sound wood, and sized for the stems they hold. Cabling works best combined with pruning that reduces the weight at the ends of the limbs, so the hardware carries less load.

When cabling is not the answer

Hardware cannot save a tree with serious decay at the base, a trunk that is already split open widely, or a root system damaged by construction or storm heave. If cabling would only delay a failure over the house, we say so and price removal instead. Cabling is also not a reason to skip inspection: it reduces risk, it does not remove it.

Upkeep

Cables and rods are not a one-time fix. Hardware should be checked every few years and after severe storms for wear, loosening and how the tree has grown around it. As the tree grows, a cable may need to be adjusted or replaced.

Trees in the right of way

Support systems on a city street tree are the city's call; Fort Wayne requires permission from its forestry office for any work on trees in the right of way. On your own lot, cabling is a way to keep a mature shade tree that would take decades to replace.
