A large American Elm was taken down today in Boston’s Public Garden across the lagoon from the Swan Boat landing. It was in failing health, and the City Tree Warden is checking tissue samples to determine whether it succumbed to Dutch Elm disease. If this is the case, the Friends of the Public Garden will treat all other elms nearby to protect them from the disease spreading. Dutch Elm disease travels by root graft, so it is important to treat trees in the vicinity of a diseased tree.
A week ago, several elms had to be removed outside of the Garden at the corner of Arlington Street and Beacon Street because of Dutch Elm disease infection. We are currently injecting the nearby trees in the Public Garden to strengthen them and ward off infection.
