Just stay away from things that would die completely in a hard freeze, such as Lychee nut for example. You are talking about things like Mangos which as ADULTS can survive a hard freeze after significant die back. Thats fine. Just don't want you wasting your time on things and hoping we don't get another hard freeze like we had about 6 years ago. Young plants in pots that don't fit the above description should be fine on cold nights now...unless there is a hard freeze. If you get into that position, then yeah take precautions since its a one off temporary thing.
