What is Arborists in the Arboretum Day?
Once a year our arborists friends from the Portland Metro area gather up their tools and swing up to Hoyt for our annual Arborists in the Arboretum Day. Each arborist spends their precious Saturday lending their experience and expertise in the careful care of our collections. We are thrilled to host this boisterous group of colleagues and are amazed at the skill and accuracy with which they do their work.
