Cables are installed in trees to provide support to weak or potentially dangerous limbs by connecting two or more limbs together.  Additional support may be needed due to split or decayed crotches, crotches with  included bark, or the inherent danger of weak-wooded trees.  Multi-stemmed trees are susceptible to breaking under the stress of wind or the weight of accumulated ice or snow. Branches that pose a potential threat to property or people below may be candidates for cabling.  In determining whether cabling is warranted, the condition of the tree should be assessed.  If the root system is not structurally sound, or if the tree contains excessive decay, removal of the tree may be preferable.  Keep in mind that support cables, even when combined with braces, have limitations.   Mechanical devices cannot always be relied upon to make a potentially hazardous tree safe. At Commercial Tree Care we can install various types of cabling systems to meet the trees needs.
