Yup, there is a freeze warning tonight. I pulled all the plants back in the greenhouse today. Takes me about an hour to move them.
This is normal for me, though, I usually have to do it a few times every year. The important thing for me was getting them out for long enough to clean up the greenhouse, check for bugs, test all the irrigation drippers, etc. With all that done moving them back in for a couple days isn't a big deal.
