So we have a Reed avocado tree that currently has a nice crop of reed avocados on it but suddenly we noticed we have lots of yellow leaves fallen off of it and on the tree there are alot of green leaves with brown tips, brown spots on the bottom, and basically brown towards the middle. The whole tree seems a bit wilted if you will. New buds have formed recently in abundance and we had added 4 of those miracle gro fruit plant stakes around the tree. We water the tree deeply once a week and then it just gets some overspray from the lawn sprinklers couple times a week. Any ideas by this and looking at the pictures of the leaves what could be going on? Here is a link to the pictures:
