I live in Northern Kentucky and have a nine year old maple in my front yard. The last two years some of the branches have not produced leaves and are brittle. The tree was about 25 ft tall two years ago but the center stalk died first and was cut back about 8 ft. The tree is still green in parts but only has about 30% of it's normal leaves. I have attached some pictures. The tree does have som Lichem ( I beleive that's the right name ). Ihave a sprinkler system that waters it most every day during the summer months. Ther are some euyomous plants at its base. Can it be saved or is it dying and in need of replacing? Thanks in advance for your help.
