Answer: Congratulations getting these to grow! To keep them from year to year woou will need to bring them indoors in the fall. Unfortunately, seed grown citrus can take many years to bear and often grow into very large trees not suitable for containers -- container growth may stunt them so they never bear fruit. For this reason, if you want to raise fruit, you might consider getting one of the dwarf citrus that do especially well in containers such as Calamondin orange. These are usually grafted onto a dwarfing rootstock such as Flying Dragon to keep them a manageable size.
