What can I do to revive an orange tree that's no longer producing fruit/?

Question:I have an orange tree in my backyard.that had been producing plenty of fruit until the past few months. I'm renting my home, and the owners said all I need to do is water the tree once a week, and it will be fine. I'm concerned that's not so true, or maybe I need to water it more than they say. What can I do to nurse this tree back to health? Any suggestions?

Answers:
Why not take a soil sample to your county extension service. Tell them what the problem is and you'll get your answer after they run test on the soil. Hope this helps.
