Our tree looks sick, I watered it today with about 4 gallons of water. The tree guy came to prune and trim it. He said they don't do well in hot climates. He said it may eventually die. Its over 5 yrs old. I live in Maryland. What can I do to keep it alive... it offers shade to my front window and I want to keep it. What should I do about this situation and the future. Thanks

You don't say where you are, and that is important, or what type of white birch you have. I suggest you visit this website:
