Answer: Rose afficionado's use Elmer's Glue on the canes right after cutting. The glue is water based so it won't burn the plant tissue, and it hardens as it dries. The material on the canes when you bought the plants was wax. Nurseries dip the cut ends in regular old candle wax. I don't recommend that, though, because if the wax is too hot it can burn the plant tissue. Good old Elmer's Glue is quick, convenient and inexpensive.
