I have an orange tree that is in this third or fourth summer _ still young and small. Its leaves are yellow-green despite fertilizer and ironite. My question is why, and what to do. It gets rather frequent deep-soak watering. It's basically in clay soil with a hard clay pan not far below its roots, though I did add enriched soil and dug a decent hole  when it was planted. Nearby quite mature citrus trees (25 years or more) have deep green leaves from much the same treatment.
