I've done a lot of searching these forums and on google. Supposedly it is safe to use. I did some trimming last month on a redbud that was growing into my service lines going to the house. I've got the limbs cut up into small chunks and sitting in the garage to season. Come spring, I'll find out how it tastes. if it is good...might have to do some more trimming...for safety's sake. I'll update once I try it, but wanted to get the thread in for anyone who has previous experience or wants to watch it.
