Hello,
I am looking for advice on how to treat my orange tree. It's been sick for a while, at first it was infested with scale and sooty mold. I scraped most of them off and sprayed with a mixture of vegetable oil, baking soda, and dish soap for several weeks, then washed the sooty mold off the leaves. I stopped spraying after the leaves began to drop. Eventually, the tree shed all of its leaves.
I trimmed back the leafless branches and repotted the tree with fresh soil. In the spring time, there was a lot of fresh growth, some of which stayed and some of which died off. Now I've noticed yellow spots starting to form on the remaining leaves (see images). Does anyone know what might be causing that? I've had this tree for over 20 years and would love to restore it back to health. Thanks!
