Gilbert homeowners deal with a unique set of tree problems every year. The desert climate, scorching summers, and periodic storms create conditions that stress even the hardiest trees. Because of this, many trees show signs of decline long before homeowners notice something is wrong.

Understanding what to look for can save your trees — and your property. Early action prevents small issues from becoming costly emergencies. Whether you have mature shade trees, ornamental palms, or desert-native species, knowing the warning signs matters.

At AZ Tree Trimming & Removal, we serve homeowners across Gilbert, Scottsdale, Mesa, Chandler, and the greater Maricopa County area. We see the same recurring issues on properties throughout the region. This guide covers the most common problems and what you can do about them.

Heat Stress and Drought Damage

Arizona summers are brutal. Temperatures regularly climb well above 100°F for weeks at a time. As a result, trees that are not properly watered or mulched begin to show visible stress.

Signs of Heat Stress in Trees

Heat stress can look like several different problems. However, the most common signs include:

• Leaf scorch: Browning or crisping along leaf edges
• Premature leaf drop: Trees shed leaves early to conserve moisture
• Wilting or drooping canopy: Even with regular watering
• Bark cracking or sunscald: Especially on young or thin-barked trees

Many Gilbert homeowners mistake heat stress for disease. Therefore, it is important to evaluate watering schedules before assuming the worst. Deep, infrequent watering encourages roots to grow deeper and access more stable soil moisture.

What You Can Do

First, check your irrigation system. Make sure water is reaching the root zone, not just the surface. Additionally, applying a layer of mulch around the base of the tree helps retain moisture and regulate soil temperature. Avoid piling mulch directly against the trunk.

If heat stress is severe, a professional assessment can determine whether the tree is recoverable. Furthermore, strategic trimming can reduce the canopy load and help the tree manage water loss more effectively.

Root Damage and Soil Compaction

In developed neighborhoods across Gilbert, Scottsdale, and Chandler, tree roots frequently face compacted soil. Foot traffic, vehicle parking, and construction activity compress the soil over time. As a result, roots struggle to absorb oxygen and nutrients.

How Root Damage Affects Trees

Root problems are often invisible until significant damage has occurred. However, surface roots lifting sidewalks or driveways are a common early clue. Other signs include:

• Thinning canopy despite adequate watering
• Slow or stunted new growth
• Yellowing leaves that do not respond to fertilization
• Leaning or unstable trunk

Girdling roots are another serious concern. These are roots that wrap around the base of the trunk and slowly restrict the flow of water and nutrients. On the other hand, they are often treatable if caught early by a trained arborist — a certified tree care professional.

Root Damage Near Structures

Roots growing toward foundations, sewer lines, or underground utilities are a major concern for homeowners. Moreover, this is one of the most common reasons families in Gilbert and Mesa call us for tree removal consultations. A professional can evaluate whether root management or full removal is the right course of action.

Pest Infestations Common in the Phoenix Area

Several pests thrive in the Maricopa County climate. These insects and organisms attack trees in ways that are easy to miss early on. Therefore, regular visual inspections of your trees are a smart habit.

Common Tree Pests in Gilbert AZ

• Bark beetles: These small insects bore into tree bark and disrupt the flow of water and nutrients. They often target stressed or weakened trees first.
• Borers: Similar to bark beetles, borers tunnel through wood and can kill branches or entire trees if left untreated.
• Aphids and scale insects: These pests feed on sap and weaken trees gradually. Also, they often leave behind a sticky residue called honeydew.
• Mistletoe: This parasitic plant is extremely common across the Phoenix metro area. It extracts nutrients from host trees and can cause serious long-term decline.

Mistletoe is especially widespread in older Scottsdale neighborhoods and communities like Paradise Valley and Cave Creek. In many cases, professional pruning to remove infected branches is the most effective management strategy.

When Pests Become Emergencies

A single pest infestation does not always mean a tree is doomed. However, multiple simultaneous stressors — drought, pests, and root damage together — can push a tree past the point of recovery. Additionally, infested trees that die become a safety hazard and must be removed promptly. AZ Tree Trimming & Removal provides 24-hour emergency service for exactly these situations.

Fungal Disease and Root Rot

While Arizona is dry, overwatering is a surprisingly common mistake. Many homeowners set irrigation systems and forget them. As a result, trees receive far more water than they need, especially during cooler months.

Identifying Fungal Issues

Excess moisture in the root zone creates ideal conditions for fungal growth. Signs of fungal disease or root rot include:

• Mushrooms or fungal conks growing at the base of the tree
• Soft, dark, or mushy wood near the root flare
• Sudden wilting even with regular watering
• Discoloration under the bark when scratched

Root rot is one of the most destructive tree problems in the Gilbert area. Furthermore, by the time outward symptoms are visible, internal decay may already be advanced. A certified arborist can probe and assess the structural integrity of the tree.

Can Affected Trees Be Saved?

In some cases, yes. However, it depends on how much of the root system is affected. First, adjusting the irrigation schedule is critical. Next, removing affected roots and improving soil drainage may help. Then, ongoing monitoring by a professional is recommended. Finally, if the tree is structurally compromised, removal is the safest option for your family and property.

Storm Damage and Wind-Related Breakage

Gilbert and the broader Phoenix area experience powerful monsoon storms each summer. These storms bring high winds, heavy rain, and lightning. Therefore, poorly maintained trees become dangerous very quickly.

Trees Most at Risk During Monsoons

Trees with the following issues are far more vulnerable to storm damage:

• Overgrown or unbalanced canopies that catch wind
• Dead or dying branches that break easily
• Weak branch unions where two limbs meet at a narrow angle
• Trees that have not been trimmed in several years

Moreover, large trees near homes, vehicles, or power lines pose the greatest risk. Proactive trimming before monsoon season reduces this risk significantly. We recommend scheduling a trim in late spring before storms arrive.

After a Storm: What to Do

After a major storm, inspect your trees carefully. Look for hanging branches, split trunks, or uprooted roots. Additionally, do not attempt to remove large limbs yourself — fallen branches under tension can snap back unexpectedly and cause injury.

Poor Pruning and Tree Topping

One of the most damaging tree problems we encounter is not caused by nature — it is caused by improper pruning. Tree topping, or cutting a tree’s main trunk down to stubs, is unfortunately still common. However, it is widely considered harmful by professional arborists.

Why Topping Harms Trees

Topping removes the majority of a tree’s canopy at once. As a result, the tree goes into shock and rapidly pushes out weak, fast-growing sprouts called water sprouts. These sprouts are poorly attached and break easily in wind. Furthermore, topping creates large open wounds that invite pests and disease.

Instead, proper pruning removes specific branches with clean cuts at the right locations. This approach preserves the tree’s structure, health, and natural shape. A skilled arborist knows exactly where and how much to cut.

Frequently Asked Questions About Tree Problems in Gilbert AZ

How do I know if my tree is dying or just stressed?

Stressed trees often recover with proper care. However, dying trees show multiple simultaneous symptoms — dead branches, bark falling off, no new growth, and soft wood. A professional inspection provides the most accurate answer.

When should I remove a tree instead of treating it?

Tree removal is the right choice when a tree poses a safety risk or is beyond recovery. Additionally, trees leaning toward structures, trees with advanced root rot, or trees that are more than 50% dead are typically candidates for removal.

How often should I have my trees trimmed in Gilbert AZ?

Most trees benefit from trimming every one to three years. However, fast-growing species or trees near structures may need more frequent attention. Palm trees in particular benefit from annual trimming to remove dead fronds.

Are tree problems covered by homeowners insurance?

Coverage varies by policy and by the circumstances of the damage. Generally, storm damage to structures may be covered. However, routine removal or maintenance is typically not. Contact your insurance provider for specifics.

What is stump grinding and do I need it after tree removal?

Stump grinding uses a machine to grind a leftover stump down below ground level. It is not always required, but it is strongly recommended. Stumps left in place can attract termites, fungi, and other pests. Furthermore, they can be a tripping hazard and may continue to produce unwanted sprouts.
