How to overwinter hibiscus?

Hi. I have a couple hibiscus planted in my flowerbed on the southern side of my house. I live in Southeastern Oklahoma.





It's supposed to get close to freezing tonight, so do I need to bring them in?





What's the best way to overwinter them? Do I need to repot them for the winter? Will they do okay in a garage? Or should I bring them inside where it's warmer and where there's natural light?

From another Okie--I bring mine in, already have them in the garage. I usually just leave them inside the garage and leave the light on all day, during the winter and then bring them out in the spring or on warm days. Mine are big, so I just leave them in my utility cart and roll it out when it gets warm.
Reply:Re-pot them and bring them inside where is plenty of light and warmth. I have had them get flowers on them when they were inside the house. Put them back out in the spring time.

Reply:I live in Nebraska and have several hibiscus. Don't do anything till next spring, then trim dead stalks close to the ground. New stalks will come from roots, but takes quite a while in the spring. These are such easy care plants. Trust me, mine grow back year after year.
