Hahaha why do people always ask these kinds of questions but they don't let us know where they live....I mean come on you could be in Africa or Iceland....I have no clue where your plants are so how can anyone help you?
Ummm well lets see I live all the way down in the sunshine state (florida). If the temps there are atleast around 70 F you should be alright even if it gets a bit colder at night...
