Trees with multiple attached stems and heavy branches reaching out at odd angles should be cabled. We use professional tools to place bolts through trunks and cable them together so that they sway together in rough winds. This prevents excessive force being applied to the branches that could cause them to snap. If you have a large tree near your home or driveway, ask us to take a look and see if we can make it safer.
