Good afternoon. We have 2 very tall elm trees in our front yard that appear to be dying or possibly dead. I've heard there is something that can be injected into the tree to possibly save it if it's not too far gone. How can we tell if there is hope? We definitely don't want to cut them down if they can be saved.

The fungicide used are considered preventatives. For trees with the first symptoms of disease (5% or less) there is some ability to eradicate the disease if the fungicides are also used with pruning. It is not going to work if the spread of the disease is from a root graft. See the following information on D.E.D. : http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/dutch-elm-disease/
