Removal of invasive vines is important to the health of your trees. Trees that have structural defects may incur storm damage from snow, ice or wind. Dead wood is brittle, and cannot bend in the wind like a living tree or branch. Branches that are already broken off and hanging in the tree should receive prompt attention. Cracks - A crack is a deep split in the tree, which extends through the bark and into the wood of the tree.
Cracks are indicators of potential branch or tree failure.
Trees usually decay from the inside, forming a cavity. At the same time, new wood is added to the outside of the tree as it grows. If the outer shell is sound, the tree may be relatively safe. Evaluating the safety of a decaying tree is best left to a trained arborist. Root Problems - Trees with damaged roots may blow over in wind storms.
