When a tree dies or begins to decline beyond recovery, it can quickly turn into a safety hazard. Dead and dying trees are more likely to drop branches or collapse during storms, putting people, homes, vehicles, and utility lines at risk. Knowing the warning signs can help you act before a dangerous situation develops. At Bassett Tree Service, we specialize in tree removal in the greater Mesa, AZ area. Here are four signs that a tree may be dead or dying and should be evaluated by an arborist.


Extensive Dead Branches Throughout the Canopy

One of the clearest indications of a dying tree is the presence of numerous dead branches throughout the canopy. While it's not necessarily concerning for a tree to lose an occasional limb, widespread deadwood often signals that the tree is no longer healthy. Brittle branches without leaves during the growing season may indicate that the tree is in serious decline. Dead branches can fall unexpectedly and should be addressed promptly.


Peeling or Missing Bark

Large sections of peeling, cracked, or missing bark can be a warning sign of disease or severe stress. If significant portions of the trunk are bare or the underlying wood appears dry and discolored, the tree may no longer be able to transport water and nutrients effectively. Extensive bark loss often accompanies internal decay and should be inspected by an arborist.


Large Cracks/Cavities

Deep cracks in the trunk, large cavities, and hollow sections weaken a tree's structural integrity. While some trees can survive with small cavities, extensive decay inside the trunk greatly increases the likelihood of failure. These issues are especially concerning if the tree is located near buildings, driveways, sidewalks, or other frequently used areas.


Fungal Growth Around the Base

The appearance of fungal growth near the trunk or root flare may indicate internal decay or root rot. Fungi feed on decaying wood, and their presence often suggests that the tree's structural support system has been compromised. Root damage is particularly dangerous because it reduces the tree's stability and increases the risk of collapse during strong winds or heavy rain.
