Ailing Coral Bark Maple
- The tree was planted professionally. The following year we accidentally broke off a couple of major branches, leaving the tree looking lopsided. I am not sure when we noticed the dark streaks on the trunk. The 3rd year we talked with an arborist about trimming the tree to make it more balanced. He diagnosed it with
- verticillium wilt, an air borne disease and nothing we could do about it but it would not hurt the tree. He trimmed it lightly in March and said it would fill in with new growth. Three days ago (May 17) a small branch (about the size of my little finger) fell off and we thought nothing of it. A day later a large branch (size of my fore arm) fell off during the night. I am enclosing pictures of the tree and the open wound left by the broken branch. Is there any hope for the tree? What is the treatment for the tree? the soil? Should we take it out and replant it?

Thank you for your explanation i=of our tree problem. Is there some way I should treat the wound where the branch broke off? or do I just need patience?
I do not know of any action you might be able to take at this time. There are no materials to apply to get rid of the problem. Keep the injured areas as dry as you can. We are heading into our summer dry period so that should be enough. It's kind of up to the tree at this point. You might think about another tree for that spot if this does not do as well as you want. Good luck.
