Have you looked up lately? Many times after a long winter, people fail to look up and notice that something is wrong with their tree. If and when people do, they are surprised to find that a tree on their property is not doing well or has died. By mid spring, every deciduous tree that is healthy has at least shown some type of sign that it is alive by either blooming or putting on new leaves. Trees with no leaves, when they should have some, are either declining, dying, or dead. Any tree that you see that has yet to become green should raise a red flag and be labeled as a hazard.
A hazardous tree is defined as any tree that might fall and cause property damage and/or bodily harm and should be removed immediately. This includes all trees that have dead branches, dieback in the top of the tree, extensive damaged or diseased areas, hollowed out, and/or are completely lacking foliage when they should not.
There are numerous reasons that cause trees to decline or die. Any time the most sensitive area of the tree, the roots, are attacked directly or indirectly, the tree will be harmed. Building construction near the tree, digging within the root zone, old age, and insects are the most common reasons. The traffic of heavy equipment during house construction causes soil compaction and limits the tree ability to take up nutrients and water. Digging, for whatever reason, ultimately always severs trees roots and limits the tree’s longevity. There is really no way to know how long a tree will live and bugs always manage to go undetected until the damage has been done.
Although the reason why a tree is unhealthy is important, your main concern should be removing that tree. Once trees begin showing symptoms like that above, they may live several more years or could come tumbling down at any moment. Leaving them is very risky. Get rid of it and go buy yourself a new and better tree.
