How do you start growing a rose from a piece of stem with no apparent root showing?

I was given a Long Stem White Rose which I placed in a vase with water. The Rose never fully bloomed. Instead, the stem started showing growth and the flower completely died. I cannot see any sign of rooting. How do I accomplish beginning a root base for the stem to continue producing growth for planting?

Make sure you cut off any flower or hip(the part under the flower) first. It will use up needed nutrients. If it's a very long stem, cut into 2-3" sections, preferably with a leaf section in each.Cut the bottom at an angle with a sharp knife or razor. Dip bottom end into Rootone or any other rooting compund(available at any garden center). I haven't had any luck with rooting roses in water. Mine do better in a small pot with moist sand. Good luck! PS. Most long stemmed roses are hybrids, so you may not get the same flower you started with.
Reply:get some B-12 from your nursery, cut the end of the stalk at an angle with a razor blade...Dip the stalk in the B-12 and plant it...The B-12 helps to promote root growth...
Reply:Try Schultz Take Root. It's a powder that you put in the container containing the water and rose. It is available at Walmart, Lowe's, etc. for less than $5. It works on other plants, too. Leave it in the water until the roots are healthy.
