I have a mature, large green, lace leaf maple that has branches that completely die during the spring and summer. First the leaves become brown and then an entire branch will die. I have been told to use a fungicide by a salesperson at McClendon's, but then was told by WA tree service that these trees usually do not get fungus and that spraying with a fungicide may do more harm than good. Help! What should I do?

Consider taking an example of what you describe to your local agricultural extension service for identification and recommendations. Most salespeople in "box stores", are trying to sell product, and in our area, tree services know how to cut or prune trees.
