Soil Health
Nourishing Urban Trees for Long-Term Health
In a natural forest, decomposing leaves provide a constant supply of nutrients to tree roots. In urban landscapes, we remove these natural fertilizers (leaves and debris), leaving the soil compacted, depleted, and stressful for trees.
Tree fertilization should always be part of a broader Plant Health Care strategy. Tree Pros provides specialized root zone support to correct nutrient deficiencies, promote robust growth, and help your trees resist pests and environmental stress.
Our Services
Our Fertilization & Soil Services
Soil Stress Relief
Alleviating soil compaction to improve oxygen and water flow to the root zone.
Nutrient Deficiencies
Diagnosing and correcting specific mineral shortages (like iron chlorosis) in Denver soils.
Root Zone Support
Deep root fertilization that delivers nutrients directly where the tree needs them most.
Mature Tree Care
Providing the essential nutrients mature trees need to maintain their vigor and defenses.
Young Tree Establishment
Giving newly planted trees the nutritional boost they need to establish strong root systems.
Seasonal Timing
Applying fertilizers at the optimal time of year for maximum root absorption and benefit.
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.
Soil Testing
We assess soil compaction, pH, and nutrient levels to determine what your tree actually needs.
Nutrient Deficiency Diagnosis
We identify specific mineral shortages — like iron chlorosis common in Denver soils — before treating.
Tree Condition Evaluation
We assess the tree's overall health, species, and age to customize the right fertilization plan.
Root Zone Assessment
We evaluate root health and growing conditions to ensure fertilization will be effective.
Treatment Alternatives
We consider whether fertilization, soil amendment, or other plant health care is the right approach.
ISA Best Practices
All recommendations follow ISA Best Management Practices for soil and nutrient 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.
Depleted Urban Soils
Denver's urban landscapes lack the natural nutrient cycling of forests, leaving soils depleted and compacted.
Iron Chlorosis
Denver's alkaline soils commonly cause iron chlorosis, a deficiency that yellows leaves and weakens trees.
Drought Stress
Chronic drought limits nutrient uptake, making professional fertilization essential for Denver trees.
Soil Compaction
Urban construction and foot traffic compact Denver soils, restricting root growth and nutrient absorption.
Seasonal Timing
Denver's climate requires precisely timed fertilization to match root activity cycles.
Mature Tree Needs
Denver's older mature trees have increased nutrient demands that urban soils cannot naturally supply.
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.
Diagnosis Before Treatment
Applying fertilizer without diagnosing the actual deficiency can waste money and even harm the tree. Our arborists test first.
Right Nutrient, Right Place
Deep root fertilization delivers nutrients directly to the root zone, bypassing surface competition from turf grass.
Timing Matters
Fertilization applied at the wrong time of year can stimulate vulnerable late growth or be wasted. Professional timing maximizes benefit.
Part of a Broader Strategy
Fertilization is most effective as part of a comprehensive Plant Health Care plan, not a standalone quick fix.
