Dear Dave, I have a backyard completely lined along the chain link fence with Rose of Sharons. There must be 20-30 of them, about l0 years old. I just bought this house in July, and am new to gardening so take what I have to offer with that in mind. The tree man who came to my place to trim some of the large branches of my holly trees, spruces, black cherry, and American elm, told me that I could consider the Rose of Sharons like weeds: cut them in early spring or summer however I wanted and they would grow like mad. He suggested that I cut them way back, into the shape that I wanted, and to do this yearly. I didn't do it during the hot summer but shall do it this coming spring. I did prune the lower branches this fall however as they put out many, many branches everywhere along the main stems. I pull up the little plants as they come up in places where I don't want them, or else they get mowed with the mower if they show up in the grass part of the back yard. I hope that this will help you some. Carolyn Zone 7 Bethesda, MD ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
