Hello! I think my tree is dying and I don’t know if it can be saved. I am in zone 10. My tree was doing fine until it got really fried by the sun and lost many leaves. Then it kept getting eaten by caterpillars and now it lost all the top leaves and the branches shriveled and the bark is getting greyish and black spots. I tried fertilizer and pesticides and nothing seems to be working. Am I too late? ☹️ Any help would be much appreciated. Thank you!
