Hi Neighbor!
To answer your question, the answer is "Yes, if the trees live". Virtually all citrus trees are grafted onto 'sour root stock'. This is a type of citrus with a very sturdy root system, but lousy fruit. By grafting, growers can get trees that are less succeptable to fungus, bugs and drought. There are several local growers that can probably tell you how to graft and where to get the root stock. Perhaps Duda farms on 426 just south of Red Bug. Or the big retail nursury just south of Duda at the light. There are several citrus growers along 441 in Apopka too.
