Our Approach
Diagnosis First, Treatment Second
Many tree diseases mimic the symptoms of environmental stress, such as drought or poor soil. Applying the wrong treatment can be ineffective or even harmful. At Tree Pros, our approach is rooted in science: we accurately identify the pathogen before recommending a solution.
Our certified arborists are experts at diagnosing and treating common Denver tree diseases, helping to restore your tree's vigor and protect the rest of your landscape.
Warning Signs
Signs Your Tree May Be Diseased
Discolored Leaves
Spotted, blighted, or unusually colored foliage.
Oozing Sap & Cankers
Sunken areas or sap on the trunk and branches.
Early Leaf Drop
Unseasonal shedding of leaves before fall.
Branch Dieback
Dead sections or thinning in the canopy.
Fungal Growth
Mushrooms or conks on trunk and roots.
Root Stress
Signs of decay or damage below ground.
Fire Blight
Blackened, scorched-looking twigs and leaves.
Pest-Related Decline
Insect damage compounding disease stress.
Arborist Assessment
The Right Recommendation Starts With the Right Assessment
Tree Pros does not automatically recommend removal. Our arborists evaluate the full picture before recommending any course of action.
Accurate Pathogen ID
We identify the specific fungus, bacterium, or virus before recommending any treatment.
Tree Condition Evaluation
We assess the overall health, structure, and vigor of the tree to determine if treatment is viable.
Environmental Factors
We evaluate soil, water, and site conditions that may be contributing to disease.
Treatment Alternatives
We explore pruning, treatment, monitoring, and preservation before considering removal.
Spread Prevention
We assess risk to nearby trees and recommend steps to prevent disease spread.
ISA Best Practices
All recommendations follow ISA Best Management Practices for disease management.

Local Expertise
Denver's Climate Demands Specialized Tree Care
Denver's unique weather patterns and urban growing conditions create specific challenges for tree health and safety.
Wet Spring Diseases
Denver's wet spring weather promotes fungal leaf diseases that can defoliate and weaken trees.
Drought-Related Decline
Chronic drought stress weakens tree defenses, making them more susceptible to disease.
Freeze-Thaw Damage
Denver's freeze-thaw cycles create bark wounds that invite bacterial and fungal infections.
Urban Soil Stress
Compacted urban soils limit root health and make trees more vulnerable to disease.
Fire Blight Pressure
Fire blight is a common bacterial disease affecting Denver's ornamental fruit trees and crabapples.
Mature Tree Vulnerability
Denver's older mature trees are more susceptible to disease and benefit from proactive monitoring.
Professional Standards
Why Professional Arboriculture Matters
Poor tree work can permanently damage structure, health, and longevity. Professional arboriculture protects your trees and property for decades.
Accurate Diagnosis Matters
Many diseases mimic environmental stress. A certified arborist identifies the true cause before any treatment is applied.
Wrong Treatments Can Harm
Applying the wrong fungicide or bactericide can be ineffective, wasteful, or even harmful to the tree and environment.
Early Intervention Saves Trees
Disease caught early is often treatable. Delayed diagnosis can allow the disease to progress beyond recovery.
Protecting the Whole Landscape
Professional disease management prevents spread to nearby trees and protects your entire landscape investment.
