I have grown lemon and grapefruit trees where the temperatures got down to 0 f occasionally.
The way I saved the trees was with frost blankets and old fashioned smudge pots.
Where I am in Arkansas now, I plan to have some citrus trees in the future but I do plan on building cover supports for them and I'll have to use the hot rock trick from my tribesmen.
I had thought of actually building a special tree green house but I've since changed my mind about building such a permanent structure.
What I'm planning now is four bolt together walls double glazed with plexiglass and using a double layer frost blanket over the top.
