Every year fifteen or more PlantAmnesty arborists (all ISA certified) volunteer their time to prune trees, often majestic old trees, in the King County area for a good cause. The Tree Programs Committee coordinates this event, which usually takes place between late winter and early summer.

Trees can be on public or private property. To nominate a worthy tree(s) or to find out when and where an event is taking place, please Contact Us to request consideration for an Arbor Day Tree Prune.
