To your rose question:  Actually, you cut a pencil sized stem and put it in dirt with a liter coke bottle or plastic over the whole thing.  (Greenhouse effect) I rooted mine indoors.  Eventually, it’ll look like it’s dead.  Then it’ll start popping out new leaves.  Then once it’s fully rooted (you can feel that it is with a slight tug) you gradually get it used to outdoors and the are you’re going to plant it in.  Then you plant it and water.  Viola!
