The mere mention of the word “root extraction” concurs up images of the dentist chair, Novocain and the shrill sound of the drilling tool, which sends a shiver up my spine! Thankfully, extraction in this context is not of tooth roots but of tree roots. Last year, while attending an arborist workshop, one of the presentation topics was in regards to the use of an arboricultural tool called an Air-Spade (a registered trademark).
