How Can Air-Spading Improve Tree Health?
A healthy exposed root flare is a critical part of the tree. If the area where trunk tissue changes into root tissue is covered with soil and kept moist over extended periods of time, the tissue breaks down. Air-spading can be used to uncover a tree's flare.
Air-spading is also used as an "investigative tool". Since roots cannot be seen below the surface, an arborist must excavate the soil to confirm any root abnormalities suspected. Clearing root flares for macro-injections is another common use for air-spading, among many others.
