Hi everyone, I am a new citrus admirer and my first tree was a dwarf Persian lime which I lost to scale infestation. This tree was a root growth of the main tree (I believe) similar to the little growth in the pot now. I'm not sure if this is the rootstock plant or not but I have decided to keep it. Everything was going well until a month ago when the new growth was accompanied by leaking clear and tasteless sap from every new emerging branch! The tree is dying back now. I couldn't find any insects on the tree. There are swellings on the new branches but nothing under them. Any ideas what this might be? Thank you!
