My orange tree seems to be dying. I live in the SF Bay Area and have several citrus trees (lemon, grapefruit, orange) in the same yard, all are doing fine except the orange tree. It started to lose leaves last year but I thought maybe it was just seasonal, but now it is looking really bad especially compared to the grape fruit tree right next to it. I attached some photos of it, I did not water at all this winter, started watering 5 minutes every 3 days about 2 weeks ago. What should I do?
