I had a neighbor with one of these and never knew her to have any problems or complaints about it. I never personally had any volunteers in my yard directly across from hers either.
I really would love to have one of these trees but wonder if they can be pruned to height and size desired or better to leave left alone. Also, how far from roses should they be planted. I have an area in mind but it is only about 10' from my roses so that may not work. I could find another place though as I really want this tree.
I do use pre-emergent on my lawn so wonder if that would help with the volunteers that most people complain about.
I'm just really curious about this tree as I love the looks and smell but a little scared to give it a try.
