Sometimes, a tree will develop two co-dominant stems rather than just a single trunk. This is often dangerous, especially if the two stems form a V because the bark grows around each stem, creating a very weak connection. Eventually the two stems WILL separate, with one or both crashing to the ground (or onto a home). One way to help save some of these trees is to install a cabling system.
Our cabling system works like a spring shock absorber system on your car. When the wind blows, the stems separate. Then the tension in the rubber within the cable line draws the stems back to their natural state, much like the spring. When we can save a tree, we will. Often a cabling system is all that's needed to give your tree many more years of life.
