Hibiscus indoors or outdoors for winter?

I live in Ontario, Canada and need to know whether or not I bring my hibiscus indoors for the winter. and exactly when I do bring it in if need be.

Hibiscus indoors or outdoors for winter?
Bring it in before the first frost, or the first one will kill the hibiscus. It is a tropical plant, and can't survive the cold. I live in Oklahoma, and I've always brought mine in the house.
Reply:I bring mine inside when the evening temperature gets around 40-ish. It's also about 6 feet tall and 3-4 feet across in a 36" ceramic pot. I imagine in Ontario ,(home of the frozen digits isn't it?) you might want to bring it in a little earlier. I also keep it in the backroom, with very little light and about no winter, and let it rest and take the season off. Then trim the heck out of it in the spring and do it all again.
Reply:must bring it in for the winter. before fraost and temps get near 0 C cut you plant a little, wast it strongly with a hose and let it dry for a day. the next day bring it in. cutting the tips will ensure that it wont bloom till summer. you plant needs to rest a little so you don want it to bloom, when indoors dont give it any water. also dont take you plant back outside till this time next year
Reply:I'm in the central part of the US. Our winter here gets about 20 to 30 below zero, at one time. I keep my hibiscus outside. I put a lot of mulch on it, though. Goodluck.
Reply:A south window is best. Don't over water it during the winter, but do water it. It will get thin and it might lose a few leaves. This is normal.
Reply:Tropical hibiscus needs to come inside in the fall and can be taken back out in the summer. Hardy hibiscus is hardy outside to zone 5a.
