Cabling & Bracing in Cleveland, OH

Cabling and bracing add support to parts of a tree that are likely to split. A cable is installed high in the crown between two leaders or limbs to limit how far they can move apart in wind or under snow; a brace rod is a threaded steel rod set through a weak fork or a crack lower down. Neither one fixes a tree. They lower the odds that a weak spot fails, and they buy time for a mature tree that shades the house or anchors the yard.

Which trees are candidates

The classic case in Cleveland is a big silver maple, red maple or Bradford pear with two or three trunks rising from one tight V-shaped fork. Bark gets pinched inside those forks, which the industry calls included bark, and that weak joint is where many trees split during heavy snow or summer storms. Other candidates are long horizontal limbs over a roof and trees with an old crack that has started to close. A tree with major decay at the base, a failing root system or a dead crown is not a cabling candidate; it is a removal.

How it is installed

The industry practice for supplemental support systems in the United States is part of the ANSI A300 standards. In general, cables are installed about two-thirds of the way from the fork to the tops of the limbs, anchored with hardware through the wood or with a synthetic system wrapped around the limbs, and tensioned to allow some natural movement. Brace rods go through the stem below or across the weak point. The crown is usually thinned or reduced at the same time so the hardware carries less load.

Snow, ice and lake wind

With about 64 inches of snow a year at Hopkins and more in the East Side Snow Belt, Cleveland trees spend months carrying extra weight. Late fall is a sensible time to install cables, after the leaves drop and the structure is easy to see, and before the first heavy lake-effect bands arrive. For oaks, scheduling the pruning part between November and February also follows the Ohio Chapter ISA's oak wilt guidance.

Upkeep

Cables and rods are not set-and-forget. Trees grow, hardware loosens and synthetic cables wear in sunlight. Have the system looked at every year or two and after any major storm. If the tree's health drops off, the support system does not change the fact that the tree may need to come down.
