Trees growing up in unnatural environments force their root systems into tight, confined spaces which leads to formation of “problem roots” known as girdling roots. Girdling roots can form in nurseries where trees are forced to grow in small containers (binding and tangling of roots, also known as, pot-bound). They can also appear around trees planted near homes, backyard structures, sidewalks, or roads. Poor nursery and planting practises are the two common ways they are introduced into landscapes.

Root collar excavation is a technique used to expose girdling roots that may be suffocating your tree and cutting off vital nutrient uptake, which leads to the demise of your tree. These roots unnaturally, tightly rap themselves around the base of the tree. A tree root collar (AKA tree root flare) is the area where the first division of roots attaches to the trunk of the tree and is the area where girdling roots form.

The process involves directing high-pressure air (using the AirSpace) at the base of the tree to displace local soil in order to inspect the root system. After the girdling roots are identified, they are carefully and selectively pruned, while keeping the tree healthy.
