On Thursday, June 18, 2026, Maine and ISA-certiied arborist Stephen Brooks and Arborjet representative Kevin Brewer met with members of the Tree Working Group and other community residents to assess and treat a significant white ash located on Waldo Avenue at Primrose Street (15 Primrose is the closest address).
We met at 9 a.m., and Brewer and Brooks registered the tree’s condition (excellent), measured its diameter at breast height (45 inches) and administered the pesticide ememectrin benzoate, known to be effective in preventing the emerald ash borer from invading and killing ash. Working at the base of the tree, they installed a small plastic port every two inches using a basic hand drill and hammer. The size and distance have been calculated to avoid damaging the tree and to keep it safe for saws if it ever needs to be removed. They then injected the pesticide. The process took about 10-15 minutes. Brooks said for a tree that size, he would charge $450. However, they administered the treatment gratis, for which we are deeply grateful. Brooks and Brewer then took questions from the group for nearly another hour. (Submitted by Carol Herwig, TWIG chair and Belfast Tree Warden)
