No longer than you have had your plants inside, it wouldn't hurt to move them back outside. However, watch the temperature - - it will still be fairly cool a night or two this week.

Most of my tropicals are inside now and I'll be moving them back outside just long enough to spray them and trim them back. With the sudden cold front, I had to just smash them into my garage with no thought of where they would go for the winter. It's weird though, the killing frost appears to only have hit limited parts of North Knox County (like my house!), and most of the city looks fine.

Thanks for the reply, we are cold and rainy now so I'll hold off moving them again. I live in Middle Tennessee and we had a windshield scraping going on Friday morning. My basil tops turned black so I cut it all down and spent some time making pesto sauce!
