CABLING AND BRACING TREES IN MEMPHIS, TN
The landscapes in, and around, Memphis, TN are home to a lot of large, mature trees. Tree cabling and tree bracing are techniques tree doctors in Memphis use to support double-trunk trees or multi-stem trees. Tree cabling and bracing systems are also used to support weak branch unions or damaged tree branches as an alternative to removing the weak or damaged tree branch.
Tree doctors install traditional tree cabling systems using lag hooks and seven-strand, galvanized cable. In basic tree cabling, such as with a double-trunk tree, the arborist will install the supporting tree cable 2/3 of the distance from the union of the two trunks to the top of the tree. Installing a tree cable helps the tree trunks move in unison and can reduce the potential for storm damage. A tree cabling system in a triple-trunk tree is usually installed in a triangular shape and a four-stemmed tree is often supported with a boxed-shaped tree cabling system. Another method tree doctors use to cable multi-stemmed trees is a ring and spoke system. In this type of tree cabling system the tree doctor runs one cable from each tree trunk to a center ring.
Memphis tree doctors sometimes use tree cabling on mature trees to give extra support to a main branch. Sometimes a mature tree has a large branch that is growing over a building or the branch may be weakened by decay. If the tree doctor removed the large branch the resulting wound might never heal or the shape of the tree might be drastically altered. In this situation installing a cable would be an alternative to the tree doctor removing the entire limb.
Tree bracing often involves using a threaded rod to support a crack in a tree or using a post to support a large, or weakened, branch. A crack in a tree trunk or large branch can be held together using threaded rods. In this situation the tree doctor drills a hole through the tree trunk or large branch. The tree doctor then installs threaded rods to keep the crack from widening. On rare occasions, and usually on historic or unique specimen trees, individual branches are supported by posts which are anchored to the ground and are attached to the branch.
With the high winds and tornados that occur in the Memphis area a tree cabling or bracing system can give owners of mature trees peace of mind. Installing a tree cabling system or tree bracing does not guarantee that the tree trunk or tree branch will never break, but is does add additional support and may increase the useful life of a mature tree or unique specimen tree. A qualified tree doctor should inspect the tree before a support system of any type is installed. The tree doctor should be called back periodically to inspect the tree and make sure the tree cabling or bracing system is still intact and functioning properly.
