Answers:    They need sunlight, apt draining soil, don't need mulching, I live within southeast Georgia and grow Lemons, Grapefruit, Limes, Navel Oranges, Tangerines, Kumquates, Calamondan, Pummelo, Satsuma Oranges, Verigated Lemon, Blood Oranges, Tangelo.

It will be planned in your phone book within the white pages. I hope this will help out you.
