I'm a bitter warmer over here but my neighbor has had a key lime in the ground that hangs over my fence for at least 20 yrs. It produces a couple of times a year. I just picked a bag full for my neice this weekend. He doesn't do anything for it but it is getting older now and a bit thin. I will probably fertilize it next spring. He was going to take it out but I asked if he would leave it in and he said sure as long as I picked all the fruit so he didn't have to clean it up. LOL
