How far back should a Hardy Hibiscus be cut above ground?

Question

I’ve heard Hearty Hibiscus should be cut back all the way from 6″ to 24″ above ground.

Answer 1

Hardy hibiscus is tolerant of severe pruning however I would not do it annually. If your shrub is over-grown, you can do "rejuvenation" pruning by cutting all the branches down to 9-12 inches in late winter before leaves appear. On an annual basis, remove 1/3 of the oldest, largest branches to the ground. Every 3 years, you have a new, youthful, fuller blooming shrub. This method also controls overall height.
