Diseased Acer x Freemanii: Treatment?

Posted by rebuscannebus 8 (My Page) on

I have a ~10 year old Acer x freemanii Autumn Blaze that over this passed winter lost a large swath of bark. Photos can be found at the link below.

Can anyone diagnose the problem based on these photos? Is there any hope of salvaging this tree, or should I just hang it up and cut it down? FYI, now that it's summer, the tree is growing vigorously and the foliage looks completely healthy. OTOH, we've now detected what look like more cracks in the bark similar to those that preceded the previous bark loss, so we're not too optimistic at this point. Any help appreciated.

RE: Diseased Acer x Freemanii: Treatment?

Losing a large swath of bark over winter sounds like sun scald or some sort of sun damage. Usually it happens from sun reflection off of the snow onto the trunk, but you live in Z8 and that may not be an issue for you.

I can't get the pic to work but it depends on the trunk/bark damage. If it only is lost 25% or so around the tree, it should be fine, 50% or so, good lukc, you'll need it, more than 50% it's likely girdled and a total loss. Without seeing your picture the best you can hope for it that it it an up and down loss and not around the perimeter of the tree.
