November and December are a great time of the year to inspect your landscape trees for hazards. Most of the leaves have fallen, leaving a clear view of the tree structure. Although some tree failures are not predictable and cannot be prevented, many failures can be prevented. By inspecting trees for common structural defects, many potential failures can be corrected before they cause damage or injury.
Stand back and look at the whole tree. Thoroughly inspect the tree for defects in the following order.
- Multiple trunks
- Weakly attached branches
- Cavities and decay
- Cracks in the trunk and branches
- Hanging or broken branches
- Dead branches
