We have a tree (eucalyptus we think) and there is a twist in the trunk and the bark is gradually flaking off the base of the tree and moving up the tree. Is there any treatment to save it? Should we cut off the large branched section where the disease seems to be moving?
Eucalyptus is an unusual tree so the normal expectations don't necessarily apply. Peeling bark is normal for this tree. The twist doesn't concern me. I'm more interested in what the leaves tell you about the tree. If they are healthy looking, you probably just face the unusual characteristics of Eucalyptus. https://www.gardeningknowhow.com/ornamental/trees/eucalyptus/peeling-bark-on-eucalyptus.htm
