I have been looking for a healthy Buddha's hand for a while. Every time I see them at a nursery they are always unhealthy looking and have yellowed leaves. Are they more cold sensitive, or just harder overall to keep healthy looking than other citrus?

They are very cold sensitive as are all citrons.

Thanks for the info. I guess I'll skip that. I am not up to covering on cold nights because it actually gets pretty cold where I am in FL (Ocala) pretty often (aside from this year). We usually get quite a few nights in the 20's and once in a while even teens. None of my other citrus (meyer, Satsuma, Orlando tangelo, Minneola tangelo, Ruby red grapefruit, Moro blood) have ever had a problem, but I guess the Buddha's hand is out. Do you know if Buddha's hand is compatible to be grafted on a Meyer, or any of my trees? I am thinking that I may be able to protect one branch of one of my tree's if I grafted Buddha's hand to it.
