I live in west central Louisiana along the 8b/9a zone line, and I am looking to expand my citrus varieties, in fact I have already started. I have 3 mature Owari Satsuma trees, only 2 are good producers though, in addition I have added a myers lemon (near an electrical service so I can keep it warm with Christmas lights during freezes), along with 3 more early season Satsumas (La Early, St Ann, and Armstrong Early, the Armstrong was the first one planted out of the set) Most recently I added a Cara Cara Orange which I also suspect will need some protection in the colder months. Ideally I would like to add something to expand my citrus harvest season into the spring, but I just don't know what to try, Perhaps Tahoe Gold or Shasta Gold, there seems to be some mixed information out there on their cold tolerance though, then of course there is finding a supplier that will ship to Louisiana. If anyone has any suggestion I would love to hear them, as it seems most discussion on cold hardy citrus is about pushing the boundaries of edible citrus as far north as possible, not about more moderate varieties in traditional fringe areas like where I live about 100 miles inland from the coast.
thanks Ike
