The Cracks  

A crack is a deep split through the bark, extending into the center of the tree. Cracks are extremely dangerous because they indicate that the tree is already failing.

Contact Tree Pros if…

  • A crack extends deeply into, or completely through the stem.
  • Two or more cracks occur in the same general area of the stem.
  • A crack is in contact with another defect.
  • A branch of sufficient size to cause injury is cracked.

    Dead Wood

Dead wood is dangerous- dead trees and large dead limbs must be removed immediately! Dead trees and branches are unpredictable and can break and fall at any time. Dead wood is often dry and brittle and cannot bend in the wind like a living tree or branch. Dead limbs and tree tops that are already broken off (“hangers” or “widow makers”) are especially dangerous! Proceed with caution.

Take immediate action if…

  • A broken branch is hanging in a tree.
  • A tree is dead or diseased.
  • A branch is dead and of is of sufficient size to cause injury or damage to your property.

    Weak Branch Unions

Weak branch unions are places where branches are not securley attached to the tree. A weak union occurs when two or more similarly-sized, usually upright branches grow so closely together that bark grows between the branches, or inside the union. The bark may also act as a wedge and force the branch union to split apart. Trees with a tendency to form upright branches, such as elm and maple, often produce weak branch unions. Weak branch unions also form after a tree or branch is topped.

Contact Tree Pros if…

  • A weak branch union occurs on the main stem.
  • A weak branch union is cracked.
  • A weak branch union is associated with a crack, cavity, or other defect.


Decaying trees can be prone to failure, but the presence of decay, by itself, does not indicate that the tree is hazardous. Advanced decay, i.e., wood that is soft, or crumbly, or a cavity where the wood is missing can create a serious hazard. Evidence of fungal activity including mushrooms, conks, and brackets growing on root flares, stems, or branches are indicators of advanced decay.

A tree usually decays from the inside out, eventually forming a cavity, but sound wood is also added to the outside of the tree as it grows. Water over time finds its way into the cavity and rots the tree from the inside out. Trees with sound outer wood shells may be relatively safe, but this depends upon the ratio of sound to decayed wood, and other defects that might be present.

Contact Tree Pros if…

  • Advanced decay is associated with cracks, weak branch unions, or other defects.
  • A branch of sufficient size can cause injury. If the thickness of wood is less than 1″ for every 6″ of diameter at any point on the trunk.


A canker is a localized area on the trunk or branch of a tree, where the bark is sunken or missing. Cankers are caused by disease. The presence of a canker increases the chance of the trunk breaking near the canker. A tree with a canker that encompasses more than half of the tree’s circumference may be hazardous even if exposed wood appears sound.

Contact Tree Pros if…

  • A canker or multiple cankers affect more than half of the tree’s circumference.
  • A canker is physically connected to a crack, weak branch union, a cavity, or other defect.


There are many types of diseases that threaten Michigan trees, most of these diseases can be treated as long as the problem is identified in the earlier stages. Sprays and injections are used to treat diseases, but in many cases the diseases are not identified in time and the tree becomes a hazard and requires complete removal. Some of the most common diseases among Michigan trees are Beach Bark disease, Dutch Elm disease, Fire Blight, Tar Spots, and Oak Wilt.

Contact Tree Pros if…

  • You suspect there may be a problem.
  • You can see clear signs of pests or disease.
  • Your tree becomes unhealthy in the spring, summer or fall.
  • You notice spotting or discoloration on the leaves.
  • The bark is showing signs of decay or detached from the trunk of the tree.

    Root Problems

Trees with root problems may blow over in storms or strong winds. There are many kinds of root problems to consider:  severing or paving-over roots, raising or lowering the soil grade near the tree, or extensive root decay.

Soil mounding, dead wood in the crown, and off-color or smaller than normal leaves are symptoms often associated with root problems. Because most defective roots are underground and out of sight, above ground symptoms can serve as the best warning.

Contact Tree Pros if…

  • A tree is leaning with recent root exposure, or the soil is mounding near the base of the tree.
  • More than half of the roots under the tree’s crown have been cut. These trees are dangerous because they do not have adequate structural support from the root system to  maintain stability.

 Inspecting Your Trees

Inspecting your trees is an important responsibility every year. Tree inspections can be done at any time of year, leaf-on or leaf-off. To be thorough, inspect trees after leaf drop in fall, and routinely after strong winds and severe storms.

Inspect trees carefully and systematically. Examine all parts of the tree, including the roots, trunk flare, main stem, branches, and branch unions. Be sure to examine all sides of the tree.

Consider the following factors when assessing trees:

Tree Condition: Trees in horrible condition may have many dead twigs, dead branches, or small, off-color leaves. Trees in good condition will have full crowns, vigorous branches, and healthy, full-sized leaves; however, green foliage in the crown does not ensure that a tree is safe. Tree trunks and branches can be quite defective and still support a lush green crown.

Tree Species: Certain tree species are prone to specific types of defects. For example, some species of trees often form weak branch unions, decay, and cankers.

Tree Age and Size: Trees are living organisms subject to constant stress. Pay particular attention to older trees, which may have accumulated multiple defects and extensive decay.


Once a tree is past the point of saving, it’s important to remove it as soon as possible. Don’t hesitate to call the top experts on tree removal Oakland County MI residents and businesses trust; Rob’s Tree Pros!
