Frost warning tonight!

So I have 4 plants outside and two of them are in large grow bags. One is a Runtzosa and the other is a God berry. We have a frost warning here even though the low tonight is around 37. The runtzosa had a small bit of mold growing so I am watching her closely. The hard part was leaving her out but the God berry has no mold so I took her in for the night. Weather may be good for a week or two so I plan to bring the God berry back out, she is too tall to keep inside

well it was 1* short from frost. Take her back out to finish more.
