I've got a hibiscus shrub in the ground for 2-3 years in So. Louisiana. Last year, I didn't cut it back at all, and it grew from about 3 feet to 6 feet with copious blooming all summer long. It's planted in a bed against the house on its north side. Last winter, it never really died back, so I just let it be, and I'm glad I did. However, I've never dealt with one this big, and I'm wondering what to do with it before winter gets here. I know they can come back from essentially a stump, but I really enjoyed having a tall, wide plant to block the window and provide habitat for lizards and other little creatures, and I doubt it'll come back to this size from a stump. What to do?
