Feijoa Tree Sick

My Feijoa tree’s leaves have black edge at the back. What is the issue? How can I treat this to make the tree come back to be healthy. Thanks a lot.

This looks bacterial! This will indicate that the area remains too wet for too long. It may take some heavier, copper based fungicides to do any good here. This, along with keeping heavily infected growth cut and disposed of away from the area, can help in recovery. Here are some articles that will help:
