How do you transplant these roses?

They are wild roses. Here is a picture of the wild roses, http://en.wikipedia.org/wiki/Rosa_arkans... . There are about 100 of them outside growing along the road and in the ditch. How can I transplant them into my yard? They are blooming right now, I transplanted 2 a couple of weeks ago, but they are not doing to good. They are alive, but are not blooming. And one of them only has a couple of leaves. What should i do?What is the best way to transplant them and keep them alive and blooming? I transplanted 1 today, and i shouldn't have because it was really hot. I got most of a thick root with it, its doing ok, kinda wilted. I watered it good. Some one told me about cutting off the dead canes, but i don't know what a cane is. Thanks in advance.
