Some of the roots of my avocado tree were removed in a construction project. It does not look good. The top looks like it died. It lost all its leaves. I cut the top. The tips of the leaves on the rest of the tree have turned brown.
The tree has a long history of being stressed. It was blown down twice in two separate hurricanes. Both times I cut the top of the tree and the branches sprouted and created a new top.
The tree is about 25 years old. It is a winter pear and the fruit is excellent.
