Q.Rainbow Eucalyptus tree lower branches dying
I have a Rainbow Eucalyptus tree, one foot tall in Sept 2016, 10 ft tall March 2017. he top of the tree has lots of new growth but the lowest branches keep dying off. Is this normal for a fast growing gum tree? I live in Hawaii in a very wet area. The tree seems healthy otherwise.

I think losing lower branches is normal for this type of tree. As long as the upper branches are healthy and the tree is still growing, everything should be fine.
