These two large "unions" as you call them have been there a very long time, but they've not been so pronounced as they are now. They really are large and ugly. I'm debating if I should just throw the buses away and start new or what as these make the bushes look very unsighly. It's kinda like having a broken leg that a doctor fixed wrong, so now your leg is bent in the wrong direction and you are left deal with it.
If I bury the base of them deep enough to not see this "bend" in their upright growth, will they continue to grow correclty and still produce great roses?
