How can I prevent my citrus tree from getting yellow leaves?
I just transplanted a nice green navel orange tree to the ground. I used a mixture of manure and topsoil. And now after 2 weeks the leaves are starting to turn yellow. What do I need to do to the soil to bring them back to healthy green again.
1. Usually that means over-watering.
2. Was this fresh manure? I'm not sure citrus can handle fresh manure. At this point, though, the damage is probably done. I wouldn't be surprised if the tree goes through some shock now, it might even drop its leaves. It'll either come back fine, or else die. That's what my plants generally do.
3. I think it is chlorosis and wet feet. You can't do much about the manure in there now, just let it rot until it holds less water and be careful about watering it. You should add some iron sulfate to your soil. Do not dig it in as citrus feeder roots are shallow.
