5 Indications that a Tree May Be Dying and Should Be Evaluated by an Arborist
AZ Desert Tree Care • 6 May 2026
Recognizing the early warning signs of a dying tree can help you take action before it becomes a safety hazard or spreads issues to nearby plants. At AZ Desert Tree Care, we can identify dying trees and safely remove them when necessary. If you notice any of the following symptoms, it’s wise to have the tree evaluated by a professional arborist.
Sparse/Thinning Foliage
Healthy trees typically produce a full canopy of leaves during the growing season. If you notice sections of your tree with sparse or missing foliage, it may indicate that the tree is under stress or struggling to survive. This is especially concerning if the issue persists through multiple seasons or worsens over time. Thinning leaves often signal problems with nutrient uptake, root health, or disease.
Dead Branches
Branches that are dry, brittle, and easily snap off are a clear sign of decline. While it’s common for trees to shed a few small branches, an increase in dead limbs—especially in the upper canopy—can indicate serious health issues. Dead branches not only reflect poor tree health, but also pose a safety risk if they fall unexpectedly.
Peeling or Damaged Bark
The bark of a tree serves as a protective layer, and when it begins to peel or fall away, it can be a serious sign of trouble. Large sections of missing bark or deep splits may expose the inner wood, leaving the tree vulnerable to pests and disease. In some cases, damaged bark can indicate internal decay or structural weakness.
Fungal Growth Around the Base
The presence of fungi growing near the base of a tree often points to internal rot. Fungi thrive on decaying organic matter, so their appearance can mean that the tree’s root system or trunk is deteriorating. This type of decay can significantly weaken the tree, increasing the likelihood of it falling.
Leaning
A tree that suddenly begins to lean or shows signs of instability should be taken seriously. While some trees naturally grow at an angle, a noticeable shift in position can indicate root damage or structural failure. Cracked soil around the base or exposed roots may further suggest that the tree is no longer securely anchored.

Regular tree pruning is an important part of maintaining healthy, attractive, and structurally sound trees. Removing dead, damaged, diseased, and poorly positioned branches can improve a tree's overall condition while reducing certain hazards around your property. However, pruning is more than simply cutting branches. Improper cuts can damage a tree and create other problems. Professional tree pruning provides the knowledge and equipment needed to evaluate a tree and perform appropriate pruning safely and effectively. At AZ Desert Tree Care, we’re happy to answer your questions about tree pruning in the greater Scottsdale, AZ area. Here’s a look at some of the FAQs. Why Should Trees Be Professionally Pruned? Professional pruning can help maintain a tree's structure, appearance, and overall health. Removing dead or damaged branches can eliminate potential hazards, while selectively removing poorly positioned growth can improve the tree's structure. Professionals can also determine which branches should be removed without unnecessarily cutting healthy growth. This helps preserve the tree while addressing specific maintenance concerns. When Is the Best Time to Prune a Tree? The ideal pruning time depends on the tree species, its condition, and the type of pruning being performed. Some trees benefit from pruning during their dormant season, while certain maintenance tasks may be appropriate at other times of the year. Dead, damaged, and otherwise hazardous branches may require prompt attention regardless of the season. A professional tree specialist can recommend an appropriate pruning schedule based on the individual tree. What Branches Should Be Removed? Professionals commonly look for dead, broken, diseased, crossing, rubbing, and poorly attached branches. Branches that interfere with structures, walkways, or other parts of the property may also require attention. However, removing too many branches at once can stress a tree and negatively affect its health. Professional pruning focuses on making appropriate cuts while preserving as much healthy growth as possible. Should I Prune My Trees Myself? Small, accessible branches may appear easy to handle, but larger branches and trees can present significant safety risks. Cutting branches incorrectly can also damage the tree or cause unexpected movement. Professional tree services have the training, equipment, and experience needed to work safely, particularly when trees are large or located near homes, power lines, and other obstacles.

As a tree dies, its wood can become increasingly brittle and vulnerable to decay, insects, disease, and structural failure. Eventually, branches or the entire tree can fall unexpectedly, especially during severe weather. Promptly having a dead tree professionally evaluated and removed when necessary can help protect your property and the people on it. At AZ Desert Tree Care, we can identify dead trees and safely remove them. Here are four reasons to promptly remove dead trees. Protect Your Home and Property A dead tree can become a serious property hazard as its structural integrity continues to decline. A falling trunk or large branch can cause extensive damage to a roof, siding, vehicles, fences, and other structures. Removing the tree before it collapses can help prevent potentially expensive damage. A professional tree service can assess the tree's condition and determine the safest removal approach. Prevent Pests and Disease Dead and decaying trees can attract certain insects and other organisms that take advantage of weakened wood. Depending on the tree's condition, it may also harbor diseases that could affect other plants and trees nearby. Prompt removal can help reduce potential sources of pests and decay taking hold throughout your landscape. A tree professional can also advise you about whether additional measures are appropriate after removal. Prevent Emergency Removal Problems Waiting until a dead tree falls can make removal more complicated and potentially more expensive. A tree that collapses unexpectedly may land on structures, become tangled in utility lines, or block driveways and access areas. Emergency situations can also leave you dealing with cleanup and property repairs at the same time. Scheduling professional removal proactively allows the work to be planned around the tree's location and condition. Reduce the Risk of Falling Branches Dead branches can become brittle and lose their structural strength over time. Large limbs may break without warning and fall onto roofs, vehicles, fences, or areas where people spend time. Removing a dead tree eliminates the ongoing risk associated with its deteriorating branches.

While tree removal is sometimes a last resort, it’s often necessary to protect people and property. Professional arborists are trained to assess tree conditions and determine when removal is the safest and most appropriate option. At AZ Desert Tree Care, we provide expert tree removal in the greater Phoenix area. Here are four common reasons that trees need to be removed by arborists. Severe Disease or Decay One of the most common reasons for tree removal is advanced disease or internal decay. Trees can be affected by fungal infections and other diseases that weaken their structure over time. In many cases, these issues are not fully visible from the outside. As decay progresses, the tree may become unstable and more likely to fail. When a tree’s health cannot be restored, removal is often the safest solution. Proximity to Structures or Utilities Trees that grow too close to homes, buildings, or utility lines can create hazards. Overhanging branches may damage roofs, siding, or windows, while roots can interfere with foundations and underground pipes. Trees near power lines are particularly dangerous, as they can lead to electrical hazards or outages. In these cases, removal may be necessary to protect both property and safety. Dead/Dying Trees A dead or dying tree is no longer structurally sound and can become unpredictable. Without healthy growth, the tree’s wood becomes brittle and more prone to breaking. Dead trees can shed branches or fall entirely, especially during strong winds. Removing a dead tree promptly helps eliminate a potential hazard. Pest Infestations Certain pests can cause significant damage to trees by feeding on wood or disrupting nutrient flow. Severe infestations can weaken a tree’s internal structure and make it more susceptible to disease. In some cases, removing an infested tree is necessary to prevent the spread of pests to nearby healthy trees. Arborists can assess the severity of the infestation and determine whether removal is the best course of action.
