overwintering tropical hibiscus
i received a rooted cutting of a nice little dbl red tropical hibiscus in late spring. It made decent growth in a pot and was just starting to bloom when I had to bring it in 2/2 temps dropping. It has 3 stems each @ 18-24" and while it seems to have completed its bloom cycle seems content in maintaining its leaves and adding tip growth on each branch. If anyone winters over their trop. hib. I'd appreciate your insights as I don't want it to get really leggy but am leery of pruning it back too far, esp. since its not dropping leaves (yet-LOL).
Thoughts from those who've managed this here in the northland? BTW it sits in a nice sunny southerly facing bay window.
