Root Flare Exposure

Specialized tree care techniques such as root flare exposure are used to address a variety of plant health concerns as well as to preserve mature trees.


Air Spading

Air spading is a non-invasive tree care technique that involves the use of pressurized air to remove soil from around the roots of trees. The goal of airspading is to expose the root system of a tree or plant in order to identify and correct issues affecting growth. 

One of the primary benefits of using airspading for root flare exposure is that it allows landscapers to assess the root system of a tree or plant without causing any damage to the roots. This is particularly important for mature trees, which may have delicate or fragile roots that are easily damaged by traditional digging methods. 

Root flare exposure can also help to remove excess soil and mulch from the tree collar to improve the overall health and correct girdling roots. Additionally, airspading can help to identify potential issues such as compaction, root rot, or nutrient deficiencies, which can then be addressed through appropriate treatment. Overall, airspading is a valuable tool for maintaining the health and vitality of trees.

Common Issues

Girdling Roots

Girdling roots are a common issue that lead to health decline and ultimately mortality in trees. They are caused by trees being planted too deep or having soil built up at the base of the trunk due to improper mulching techniques over time. Without remediation, girdling roots ultimately choke the tree. It is important to identify signs of stress due to girdling roots early so that they can be exposed and corrected.

Popular & Frequently Asked Questions About Root Flare Exposure

What is air spading?

Air spading is a process that uses compressed air to remove soil from around tree roots or underground utilities. The compressed air is directed at the soil to loosen it, which makes it easy to remove without damaging the roots or surrounding utility lines, irrigation, or hardscape.

When is root flare exposure necessary?

Root flare exposure is often used in landscaping and tree care when the roots of a tree need to be examined or treated. Girdling roots due to improper planting and mulching are the most common issue necessitating root flare exposure. It is also commonly used in tree preservation when trenching for underground utilities or revising irrigation without hurting the tree.

How is air spading different from traditional excavation?

Traditional excavation involves using heavy machinery, which can damage tree roots or underground utility lines. Air spading is a more delicate process that uses compressed air to loosen the soil without causing damage.

What are the benefits of air spading?

Air spading is a non-invasive process that helps preserve the health and longevity of trees by protecting their roots. It can also be used to excavate soil around underground utilities without causing damage. In addition, it can help identify any issues with the roots or utilities before they become major problems.

How long does air spading take?

The length of time it takes to complete an air spading project depends on the size of the area that needs to be excavated. However, air spading is generally faster than traditional excavation methods.

Is air spading safe for trees and other plants?

Air spading is generally safe for trees and other plants because it is a non-invasive process that does not damage roots. In fact, it can help preserve the health and longevity of trees by protecting their roots.

Can air spading be used for all types of soil?

Air spading can be used for most types of soil, but it may not be as effective in extremely compacted or dense soil. Certified Arborists will be able to examine the soil structure and recommend the best approach for the situation.
