Pruning Rose of Sharon
I have a number of these plants and they have grown from 4 ft to over 8 ft and I need to know how hard I need to trim they and when. I live in the northeast and don't want to damage them and still want the flowers next year. Usually I have taken about 1 to 2 feet off the top and they just keep getting taller.

You can prune rose of sharon pretty hard because, as you have seen, they grow very quickly. It would be best to prune them in the spring and this will not affect its ability to bloom.
