Below-Ground Tree Care
Soil & Root Care in Montgomery, Alabama
A tree can only be as successful as the environment its roots are growing in. Anderson Arborworks provides professional soil and root care throughout Montgomery and Central Alabama to address compaction, buried root collars, poor soil structure, restricted rooting space, and other below-ground conditions that can affect tree health.
Healthy Trees Start Below Ground
Most of the root system that supports a tree is hidden beneath the surface, which means important problems can develop long before they are obvious in the canopy.
Compacted soil can reduce pore space for air and water. Excess soil or mulch around the trunk can bury the root collar. Construction, grading, traffic, restricted planting areas, and poor soil structure can all influence how roots develop and function.
When a tree is struggling, the answer is not always more fertilizer or more pruning. Sometimes the most important work happens in the soil.
Soil & Root Care Services
Root Collar Excavation
Excess soil or mulch around the base of a tree can hide the natural root flare and create unfavorable conditions around the trunk and structural roots. Careful excavation can expose the root collar and help determine what is occurring below grade.
Soil Decompaction
Foot traffic, equipment, construction, and years of landscape activity can compress soil and reduce the pore space roots need for air and water. Targeted decompaction can help improve the physical growing environment.
Air Excavation
Compressed air can be used to carefully remove or loosen soil around roots while reducing the likelihood of damage that may occur with conventional digging tools.
Organic Matter Incorporation
Where appropriate, organic matter can be incorporated into disturbed or compacted soil to help improve soil structure and support a more favorable rooting environment.
Root-Zone Improvement
Trees growing in lawns, construction sites, parking areas, and other developed landscapes may have limited usable soil volume. Root-zone improvements are selected around the limitations of the individual site.
Soil & Tree Fertility
Soil conditions and tree nutrition are closely connected. When appropriate, soil improvement can be paired with targeted tree fertilization as part of a broader tree-care plan.
Soil Compaction Can Limit Root Growth
Healthy soil contains pore spaces that hold both air and water. When soil becomes heavily compacted, those spaces are reduced. That can make it more difficult for roots to expand through the soil and can change how water and oxygen move through the root zone.
Compaction is common around established landscape trees, especially where lawns are heavily used, vehicles or equipment have traveled over the root zone, construction has occurred, or soil was heavily disturbed during development.
Improving compacted soil does not mean simply digging around the roots. The goal is to improve soil conditions while minimizing unnecessary root injury.
Common causes of compaction include:
- Construction activity
- Vehicle and equipment traffic
- Repeated foot traffic
- Grading and site development
- Working wet soils
- Restricted planting areas
- Long-term landscape use
The Trunk Should Not Disappear Into the Ground
A properly positioned tree typically widens near the base where the trunk transitions into the major structural roots. This area is commonly called the root collar or root flare.
When a tree looks more like a telephone pole entering the soil, the root collar may be buried beneath excess soil, mulch, or fill. Trees can also be planted too deeply from the beginning.
Root collar excavation allows us to carefully expose this area and better understand the relationship between the trunk, structural roots, surrounding soil, and existing grade.
Why Use Air Around Tree Roots?
Tree roots can be damaged easily by shovels, trenchers, and other conventional excavation equipment. When work needs to occur close to important roots, compressed-air excavation can provide a more controlled method of exposing or loosening soil.
Air excavation can be useful for investigating buried root collars, loosening compacted soil, examining important roots, and performing targeted root-zone work without relying on aggressive mechanical digging.
The objective is not simply to remove soil. It is to gain access to the root zone while preserving as much functional root tissue as practical.
Air excavation may be useful for:
- Root collar excavation
- Investigating buried roots
- Targeted soil decompaction
- Working around structural roots
- Evaluating below-ground conditions
- Incorporating soil amendments
Landscape Soil Is Not Forest Soil
Trees evolved in environments where leaves, wood, and other organic material regularly return to the soil. Residential and commercial landscapes are very different.
Topsoil may have been removed during construction. Subsoil may have been compacted during grading. Turf competes for resources, leaves are removed, mulch areas may be small, and roots may be confined by pavement, foundations, curbs, utilities, or other structures.
Good soil and root care recognizes those limitations and works within the realities of the developed landscape rather than treating the tree as if it were growing in an undisturbed forest.
Fertilizer Cannot Fix Every Soil Problem
Adding nutrients does not correct heavily compacted soil, a deeply buried root collar, restricted rooting space, or poor drainage.
A tree may have adequate nutrients available but still struggle because its roots cannot adequately explore the soil or because the physical root environment is unfavorable.
Anderson Arborworks offers both soil and root care and tree fertilization so those services can be used independently or together when the situation calls for it.
The limiting factor may be:
- Compaction
- Buried root collar
- Restricted soil volume
- Drainage
- Moisture availability
- Construction disturbance
- Soil structure
- Nutrient availability
Why Choose Anderson Arborworks for Soil & Root Care?
We Look Below the Canopy
Tree problems are not always caused by something occurring in the branches. We consider the soil and root environment when below-ground conditions may be contributing to the concern.
Targeted Soil Improvement
Soil work should address an actual limitation. We focus on the conditions present around the tree rather than assuming every property needs the same treatment.
Care Around Important Roots
Working around established roots requires care. Techniques such as air excavation allow targeted work in the root zone while reducing unnecessary mechanical disturbance.
Whole-Tree Care
Anderson Arborworks provides pruning, fertilization, soil and root care, and removal, allowing recommendations to consider both the tree above ground and the environment supporting it below ground.
Other Tree Care Services
Tree Fertilization
When nutrient availability is part of the concern, targeted fertilization can complement improvements to the physical root-zone environment.
Tree Pruning
Professional pruning can improve structure, provide clearance, remove deadwood, and guide the long-term development of young and mature trees.
Tree Removal
When a tree cannot reasonably remain in place, Anderson Arborworks provides professional tree removal using skilled climbing, rigging, and controlled removal techniques.
Frequently Asked Questions About Soil & Root Care
How do I know if the soil around my tree is compacted?
Compaction is common where construction, equipment, vehicles, or repeated foot traffic have occurred. Poor infiltration, difficult digging, restricted root development, and a history of site disturbance may all suggest compacted conditions.
What is root collar excavation?
Root collar excavation is the careful removal of excess soil or mulch from around the base of a tree to expose the transition between the trunk and major structural roots. It can help reveal whether the tree was planted too deeply or whether soil has accumulated around the trunk over time.
What is an AirSpade?
An AirSpade is a tool that uses compressed air to move and loosen soil around roots. Because the air stream can remove soil without cutting through roots in the same way that a shovel or excavator might, it is useful for certain types of root-zone investigation, excavation, and soil work.
Can compacted soil be fixed?
Soil conditions can often be improved, although the appropriate approach depends on the severity of compaction, soil type, site use, root distribution, drainage, and available rooting space. Soil improvement is generally better viewed as management of the growing environment rather than an instant cure.
Should I be able to see the root flare on my tree?
In many trees, the base of the trunk should widen as it transitions into the major structural roots. If the trunk enters the soil with little or no visible flare, the root collar may be buried and further evaluation may be appropriate.
Will soil care save a declining tree?
Not necessarily. Tree decline can result from many causes, and improving soil conditions cannot reverse every structural, environmental, or biological problem. Soil and root care is most useful when the root-zone environment is an important part of what is limiting the tree.
Is soil care the same as fertilization?
No. Fertilization primarily addresses nutrient availability. Soil and root care can address physical conditions such as compaction, buried root collars, soil structure, and restricted rooting environments. The services may be used together when appropriate, but one does not automatically replace the other.
Better Trees Start With Better Rooting Conditions
If your tree is growing in compacted soil, has a buried root collar, or appears to be struggling with its growing environment, Anderson Arborworks can help evaluate the root zone and determine whether targeted soil and root care makes sense.
