Hi my orange tree is got something wrong with it the fruit for one the oranges keep falling off before it fully ripens and each orange keeps getting a big round type of hard spot on them, I did notice some of the branches died and had some type of scale on them but not all branches just a few and I cut them off, so I got a picture of the orange with the spot on it in hopes someone can tell me what it is and if its treatable, Thanks in advance. BTW this orange didn't fall off the tree I picked it almost ripe but many of the oranges produce the same type hard spot.
