I have some bad news about your citrus. First the tree that grew back, it grew back from below the graft so you do not have an orange tree. By the look of the thorns I am going to guess in about 10 years you will get something called rough lemon, which is not very good. As for your other citrus, it just doesn't do well in Florida anymore. Greening will eventually kill those trees, before it does it will make it unproductive. I have had a little success moving trees to about 50% shade and keeping the soil very acidic. I reccomend replacing the citrus with mangos. Mangos are about as cold tolerant as your lime tree with many fewer problems. If you really want limes I have had success with limequat in part shade. They get Greening like other citrus, but they still seem to produce fruit. Best wishes to you.
