Pruning Young Elms: Crown Structure Training to Promote Longevity

When: 
Saturday, October 30, 2021 - 10:00am to 12:00pm
Where: 

Berkshire Botanical Garden

CANCELED Tom Zetterstrom was a major contributor of photographs and text for the widely respected Pruning Young Elms manual published by the University of Minnesota in 2009. He has lectured on elm pruning throughout the Northeast. This talk is designed for arborists, tree wardens, arboretum directors and staff, and nursery and landscape professionals. Continuing Education Units are available through the International Society of Arborists, ISA, and Mass Arborists Association, MAA. A hands-on pruning workshop by arborist Kieran Yaple of Race Mountain Tree Services will follow the talk.  Kieran will prune the Berkshire Botanical Garden’s Princeton American elm, which was planted in 2003.


Tom Zetterstrom’s photographic record reveals a changing landscape impacted by species decline, alien plant invasion and forest collapse. In these talks he will describe projects in Connecticut and Massachusetts that have protected trees in natural and community forests. In 1999 he co-founded Elm Watch. Tom received the 2011 Public Awareness of Trees award from the National Arbor Day Foundation, and the 2013 Connecticut Urban Forest Council’s meritorious service award for efforts “to educate and promote positive change regarding trees and plants.” He is recognized for his Portraits of America Trees exhibition and his photographs are in the collections of 43 museums nationally.
