Your Alaska Tree Expert
Alaskan Southcentral Trees (Birch, Aspen, Cottonwood, Spruce, Alder, Willows, etc.) have a very shallow root system – no tap root. Most root systems aren’t much more than 2 feet deep. 90% of roots are within the dripline (the outermost branches of a tree). Cottonwood trees seek water and roots have reached out hundreds of feet from the trunk of the cottonwood.
Complete removal of stump and roots can only be done with a hydraulic excavator (as seen above). A sump grinder has its’ place, but is limited to sensitize/ confined areas. Think of a stump and root system as an upside down umbrella. Sump grinding only does half of the job by removing only the head or stump, not the root mass.
