Here’s a quick post to alert readers to the Massachusetts Arborists Association Special Seminar and Demonstration on air tool use. A team of four arborists — Mike Furgal, Matt Foti, Rolf Briggs, and Dave Leonard — will be showing how compressed-air tools can be used in arboricultural work (root forensics, bare-root planting, bare-root transplanting, shrub moving, etc.), and will discuss the advancements that this technology provide those working with or using woody plants in the landscape.
The seminar will be on September 10 at Elm Bank, the Massachusetts Horticultural Society’s property in Wellesley, MA — check the MAA link above for registration information. Registration is not limited to arborists, so interested landscape architects and contractors can go and see this work. I highly recommend signing up; last year’s seminar at Matt Foti’s farm, where Mike Furgal debuted the air-tool transplanting method, was really outstanding, and this year there’s bound to be even more information available and a great deal of informed and informative discussion.
One point: Bare-root transplanting, either with an air-tool or by root-washing, may never replace other methods of transplanting. But for specimen tree transplanting, where the value of an existing tree merits the effort involved, it is currently the gold standard. The number of roots retained with bare-root transplanting prevents the tremendous stress caused by other methods, and should be considered a valuable tool in the kit available to landscape architects, arborists, and contractors.

Bare-rooting allows for the moving of a tree this large in less than one day...

while preserving this much root mass.
