I can't figure out my orange tree, looks like its dying
I have an orange tree that came with my house, I love it, it was in bad shape when we moved in, lots of dead branches (the top reflects what the body used to look like) I trimmed it a while ago, it was fine, I then got a drip system, and put it on, and watered it for 20minutes 3 times a week. I think then is when it started to look like this. So I stopped watering it, it didn't look like it helped.
I have those sprinklers that go spray a half circle slow, then return back fast, the kind that to tst tst tst tst tststststststststst tst tst tst etc. :P It used to hit the tree, because I used that to start watering it again. The tree doesn't react to anything. I fertilized it with citrus fertilizer in march, I changed the way the sprinklers spray so they don't go by the tree, in the picture I can't remember but you can see the dead grass that no longer is watered near the tree.
