rose of sharon trunk rot on bottom back

Question

It looks like my rose of sharon has trunk rot on back bottom thats on the back & the leaves are wilting. I tried giving it lots of water because it’s been very hot. But the leaves are still hanging. So, I inspected the trunk & found this large area of what appears rotted trunk in the back that looks dark & feels soft when touched. Can this bush be saved?

Answer 1

It could be a root rot since there seems to be a problem with the water uptake. Cotton root rot is a problem with rose of Sharon but not normally in your area. Here is more information:
