In spring 2009 we got a tulip tree and planted it in the yard. Sadly, last fall the tree was murdered by a couple of deer who decided to come along in the middle of the night and chew the tree up so badly that it died. Now within the last few weeks we have been noticing little offshoots(suckers) growing from the base of the dead tree. Here's a pic https://www.flickr.com/photos/17398687@N02/4673544686/
Is there any way I can start a new tree/graft from the offshoots? I do have some rootone if that applies here, but I have no idea how I'd go about starting a new tree from the suckers. Is it possible? If so, how?
