A friend of mine has maple trees that have no bark on the trees starting from the from the ground and extends up the tree, different heights per tree, from 1 foot to as much as 15 or 20 feet, always on the west side of every tree. Sometimes on more than one side. The worst tree has a NEWER lesion (canker) about 3 feet long on a small branch that follows the same vertical line as the older damage.
There is 1 norway, and 6 or 7 silvers. All have the same symptoms. Wide span of ages/sizes, 3 inch to 18 inch. There is also a lot of box elders in lot next door, but they look like all box elders around here.
There are as many non-maples in the yard, all healthy (no mechanical damage/sun burn).
I'd just remove the silvers, the norway still looks OK for the time being, but does anyone know what this disease is? I've never seen it so extensive.
thanks...
